description: GASTROPODA  SUBGENERA AND HIGHER TAXA   Actaeonidea Gabb, 1872c: 273; 1872d: 245. Type Species: Actaeonidea oryza Gabb, 1872c: 273, pl. 11, figs. 8, 8a, by monotypy.   
 Agasoma Gabb, 1869 a: 46. Type Species: Clavella sinuata Gabb, 1866: 4, pl. 1, fig. 7, by SD of Cossmann (1901: 198). See Stewart (1927: 399) for a discussion of the nomenclatural history of the type species selection of this genus.   
 Arrhoges Gabb, 1868: 145. Type Species: Rostellaria occidentalis Beck 1836: 156, by OD. Remarks: Described as a subgenus of Aporrhais da Costa, 1778.   
 Ataphrus Gabb, 1869b: 171. Type Species: Ataphrus crassus Gabb, 1869b: 171, pl. 28, fig. 54, by monotypy. Remarks: Considered a nomen dubium by Kaim et al. (2014: 408).   
 Atresius Gabb, 1869b: 168–169. Type Species: Atresius liratus Gabb, 1869b: 169, pl. 28, fig. 50, by monotypy. Remarks: Kiel et al. (2008: 691) provided an emended diagnosis of Gabb’s genus. Kaim et al. (2014: 419) included Atresius in their new family Paskentanidae.   
 Brachysphingus Gabb, 1869b: 155–156. Type Species: Brachysphingus sinuatus Gabb, 1869b: 156, pl. 26, fig. 35, by SD of Cossmann (1901: 221).   
 Cyclomolops Gabb, 1868: 142. Type Species: Rostellaria sublaevigata Deshayes, 1865: 460, pl. 90, figs. 5, 6, by SD of Cossmann (1904: 30). Remarks: Gabb (1868) indicated, by monotypy, the type species of Cyclomolopos (a Paris Basin Eocene genus) to be Rostellaria laevigata Melleville, 1843, but according to Cossmann (1904: 30–31), Melleville (1843: 71, pl. 10, figs. 10–11) based his species on fragments. Melleville’s figure 10 is an abapical view, and his figure 11 is a sketch of inferred features, thus R. laevigata is a nomen dubium. Apparently, Gabb did not know this when he saw Melleville's figures.

 Endoptygma Gabb, 1876b: 302. Type Species: Phorus umbilicatus Tuomey, 1854: 169, by monotypy. Remarks: Junior synonym of Xenophora Fischer von Waldheim, 1807, according to Sohl (1960: 96).   
 Eripachya Gabb, 1869b: 148–149. Type Species: Neptunea ponderosa Gabb, 1864b: 88, pl. 18, fig. 38, by SD of Cossmann (1901: 147).   
 Eucheilodon Gabb, 1860 i: 379–380. Type Species: Eucheilodon reticulata Gabb, 1860 i: 380, pl. 67, fig. 18, by OD. Remarks: Aldrich (1895: 61) made Eucheilodon a subgenus of Borsonia Bellardi, 1839, but numerous others (i.e., Gardner 1945: 249; Palmer & Brann 1966: 665; and Dockery 1977: 93) considered Eucheilodon a full genus.   
 Exilifusus Gabb, 1876b: 278–279. [Junior homonym of Exilifusus Conrad, 1865]. Type Species: Fusus (Exilifusus) kerri Gabb, 1876b: 279, pl. 17, fig. 1, by monotypy. Remarks: Described as a subgenus of Fusus Bruguière, 1789.

 Megistotoma Gabb, 1864b: 144. Type Species: Megistostoma striata Gabb, 1864b: 144, pl. 21, figs. 108–108b, by monotypy. Remarks: Considered a subgenus of Philine Ascanius, 1772 by Allen (1970: 76) and Dockery (1977: 104).   
 Metulella Gabb, 1872c: 270; 1872d: 206. Type species: Metulella fusiformis Gabb, 1872c: 270, pl. 11, fig. 3, by OD.   
 Molopophorus Gabb, 1869b: 156–157. Type species: Bullia (Molopophorus) striata Gabb, 1869b: 157, pl. 26, fig. 36, by monotypy. Remarks: Described as a subgenus but treated as a full genus by Dickerson (1915: 66–67) and Stewart (1927: 389).   
 Odontopolys Gabb, 1860 i: 377. Type species: Murex (Odontopolys) compsorhytis Gabb, 1860 i: 377, pl. 67, fig. 16, by monotypy. Remarks: Considered a full genus by Garvie (1991: 89–90; 1992: 187–190).

 Palaeatractus Gabb, 1869b: 147. Type Species: Palaeatractus crassus Gabb, 1869b: 148, pl. 26, fig. 26, by monotypy.   
 Parkeria Gabb, 1881c: 368. [Junior homonym of Parkeria W.B. Carpenter, 1870]. Type species: Umbonium vitreum Gabb, 1872d: 243, unfigured, by monotypy. Remarks: Parkeria Carpenter, 1870 was initially considered to be a foraminiferan (Kingdom Protista) and Gabb’s Parkeria would therefore not be junior homonym. However, closer investigation demonstrated that it was actually a hydrozoan, according to Hill & Wells (1956: F88), thus Gabb’s name is, in fact, a junior homonym.   
 Perissolax Gabb, 1861e: 66–67. Type Species: Fusus trivolvus Gabb, 1860 a: 94, pl. 2 fig. 5, by OD. Remarks: Gabb listed both Fusus longirostris and F. trivolvus as types of Perissolax and listed F. longirostris first. Although Stewart (1927: 427) reported that F. trivolvus Gabb (1860a: 94, pl. 2, fig. 5) “seems” to have been been chosen by Gabb as the type species, Gabb did not clearly designate a type species for his genus. In addition, both species are based on steinkerns. Squires (2015: 579) reported therefore, without equivocation, that Perissolax is a nomen dubium. For an overview of the complex nomenclatural relationship between Perissolax and Pseudoperissolax Clark, 1918, see Squires (2015). Wenz (1943: 1304) regarded Perissolax as a junior synoynym of Pyropsis Conrad, 1860, but Squires (2011b) reported that Perissolax cannot be put into synonymy with Pyropsis.   
 Petropoma Gabb, 1881 a: 281–282. Type species: Petropoma peruanus Gabb, 1881 a: 282, pl. 40, fig. 8, by monotypy. Remarks: See McLean & Kiel (2007: 257) for taxonomic comments on Petropoma.   
 Phyllocheilus Gabb, 1868: 140. Type species: Pterocera ponti Brongniart, 1821: 570, pl. 7, figs. 3A–3B, by SD of Cossmann (1904: 67). Remarks: Described as a subgenus of Pterocera Lamarck, 1799.   
 Planorbella Gabb, 1872c: 270; 1872d: 201. [Junior homonym of Planorbella Haldeman, 1843]. Type species: Planorbella imitans Gabb, 1872c: 270, pl. 11, fig. 2, by OD; assigned to Limacina (Striolimacina) by Janssen (1999: 13) and reassigned to Striolimacina by Janssen (2003: 168).   
 Plochelaea Gabb, 1872c: 271 [numbered 971] –272; 1872d: 216. Type Species: Plochelaea crassilabra Gabb, 1872c: 271 [numbered 971] –272, p. 11, fig. 5, by OD.   
 Prisconatica Gabb, 1881 a: 277–278. Type species: Lunatia pedernalis Gabb, 1869d, not Natica pedernalis Roemer, 1849; by OD. Remarks: Type species figured by Gabb (1869d: 259, pl. 35, fig. 3) and identified erroneously as Lunatia pedernalis Roemer, 1849. See Squires & Saul (2004a: 31) for a discussion of the type species.   
 Ptychosyca Gabb, 1876b: 294. Type Species: Ptychosyca inornata Gabb, 1876b: 295, pl. 17, figs. 2 –4, by monotypy.   
 Rostellariidae Gabb, 1868: 141. Remarks: Recognized as a family by Kronenberg & Burger (2002: 43).   
 Rostellariinae Gabb, 1868: 141. Type Genus: Rostellaria Lamarck, 1799 [junior objective synonym of Tibia Röding, 1798, according to Bouchet (2014) in MolluscaBase accessed through WoRMS (Marinespecies.org)]. Remarks: The family name Rostellariidae Gabb, 1868 is derived from Rostellarinae Gabb, 1868: 141, a misspelled name that should have been spelled as Rostellariinae, according to Kronenberg & Burger (2002: 43).   
 Spirocrypta Gabb, 1864b: 136–137. Type species: Crypta (Spirocrypta) pileum Gabb, 1864b: 137, pl. 29, figs. 233–233b, by OD. Remarks: Described as a subgenus of Crypta Humphrey, 1797.   
 Struthiolariinae Gabb, 1868: 147. Remarks: Recognized at family level by Bouchet & Rocroi (2005: 253). Sycodes Gabb, 1869b: 160. Type Species: ? Ficus cypraeoides Gabb, 1864b: 105, pl. 19, fig. 58, by monotypy. Remarks: See? Ficus cypraeoides, which was assigned by Gabb (1869b: 160) to Sycodes Gabb, 1869b. Whiteaves (1879: 125) synonymized Sycodes glabra (Shumard, 1858) [as Pyrula glabra] with Sycodes cypraeoides (Gabb). See Squires & Graham (2014: 778) for a complete synonymy.   
 Tessarolax Gabb, 1864b: 126. Type species: Tessarolax distorta Gabb, 1864b: 126–127, pl. 20, figs. 82–82b, by monotypy. Remarks: See Saul & Squires (2015) for a thorough overview of this genus.   
 Trochifusus Gabb, 1876b: 285. Type species: Pyrula trochiformis Tuomey, 1854: 169, by OD.   
 Urosyca Gabb, 1869b: 159. Type species: Urosyca caudata Gabb, 1869b: 159, pl. 27, fig. 38, by monotypy. Urosyca is a junior synonym of Priscoficus Conrad, 1866, according to Stewart (1927: 379–380) but Squires (2014a: 5) reinstated Gabb’s genus. Gardner (1939: 30) noted that Cossmann (1904: 124) had stated “ Fulguroficus is synonymous with Urosyca Gabb 1869.”   
 Volutoderma Gabb, 1876b: 289. Type Species: Volutilithes navarroensis Shumard? Gabb 1864b: 102–103, pl. 19, fig. 56, by OD, Gabb (1876b: 289), unfigured. Not Volutilithes navarroensis Shumard, 1861 (a Texas Cretaceous gastropod). Volutoderma navarroensis (Gabb, 1876b) = Fusus averillii Gabb, 1864b: pl. 18, fig. 34, a northeast Pacific slope Cretaceous gastropod. See Saul & Squires (2008a: 216, 218, 226) for additional details.   
 Volutomorpha Gabb, 1876b: 290. Type Species: Volutolithes conradi Gabb, 1860 g: 300–301, pl. 48, fig. 10, by OD.   
 Whitneya Gabb, 1864b: 103–104. Type Species: Whitneya ficus Gabb, 1864b: 104, pl. 28, fig. 216, by monotypy.
