description: <i>Hyalorisia galea</i> (Dall, 1889) MOTU-1 (Figs 3A, 4A, 7A, J, 8C, D) <i>Capulus</i> (<i>Hyalorisia</i>) <i>galea</i> Dall, 1889: 288, pl. 14, fig. 3 [off Barbados (Blake stn 275), 12°58 N, 59°27 W, 397 m; holotype USNM 508724]. <i>Capulus galeus</i> (<i>sic</i>)— Robinson, 1983: 9. <i>Hyalorisia galea</i> (Dall, 1889) — Gracia Clavijo, Ardila &amp; Díaz, 2004: 52, fig. 22. Rosenberg, Moretzsohn &amp; García, 2009: 635. Daccarett &amp; Bossio, 2011: 64. García, 2012: 34, fig. 4. <i>Plesiothyreus galea</i> — Christiaens, 1989: 22. <i>Material examined</i>: The holotype (only photographic images examined; Fig. 8 A–C) and other material (MNHN-IM-2013-60195, MNHN-IM-2013-61224, MNHN-IM-2013-61525 and MNHN-IM-2013-61536). <i>COI-based diagnosis</i>: Ten diagnostic (autapomorphic) positions in alignment: 74(C), 145(T), 184(G), 208(G), 304(T), 418(A), 424(T), 601(C), 622(A) and 637(T). <i>Shell (data for holotype shown within parentheses)</i>: Size medium to large for the genus: length 13–25 (15.5) mm, width 9–21 (10.7) mm, height 2.5–8 (4.9) mm; thin, rounded, ellipsoidal or ovoidal, depressed; white shell surface with smooth yellowish periostracum; anterior margin rounded or very slightly angled; protoconch of 1– 1.2 whorls, diameter of nucleus 0.17–0.20 mm; teleoconch smooth except for distinct commarginal growth ridges; apertural margin thin, interior glossy white; lamella narrow, width 0.14–2 (0.14) mm. <i>Soft parts (ethanol preserved)</i>: Head, cephalic tentacles, pseudoproboscis and mantle whitish. <i>Radula</i>: Taenioglossate, 2-1-R-1-2; marginal teeth sickle shaped; lateral teeth triangular, outer edge smooth or with few denticles, inneedge smooth or with one denticle; rachidian tooth triangular, highly denticulated on both edges. <i>Host</i>: Two individuals of <i>H. galaea</i>, MNHN-IM-2013-60195 and MNHN-IM-2013-61224, were attached to two examples of <i>Propeamussium dalli</i> (MNHN-IM-2013-60196 and MNHN-IM-2013-61223, respectively). Two other specimens of <i>H. galaea</i> (MNHN-IM- 2013-61525 and MNHN-IM-2013-61536) were collected at stations where the only Propeamussiidae found were <i>P. dalli</i> and <i>Parvamussium cancellatum</i> (E. A. Smith, 1885). García (2012: fig. 4) reported <i>H. galea</i> attached to a living <i>Propeamussium</i> sp. from the Gulf of Mexico, off Louisiana. <i>Distribution</i>: From the Louisiana Slope to Barbados and the Caribbean coast of Colombia, at depths of 397– 835 m.
