Paratype: 1♀, P.63969, Australia, WA, North West Shelf, -19.94° 117.8983°, 44 m, 25 Jun 1983, CSIRO North-West Shelf project, FRV Soela, 03-B2-S | 0383 B02 S, in AM.   
 Etymology. The species is dedicated to Dr Jim Lowry, retired Principal Research Scientist, specialist in tropical Amphipoda, from the Australian Museum, as a sign of gratitude for all the generous help and advice he offered to me during my work in their collection of Cumacea.   
 Diagnosis. Carapace with 1 circular sulcus; pereopod 2 dactylus 4 propodus length, with digitiform tip; uropodal peduncle 2.16 pleonite 6 length, serrate, 2.4 exopod length; exopod 1.08 endopod length; both rami with terminal microserrate setae.   
 Description. Carapace 0.54 entire body length, 2 longer than high, 2 lateral ridges, as long as carapace, delimiting one circular sulcus; small ocular lobe with 3 small lenses, small tubercle at basis; small antennal notch (Fig. 20 A, B). — Antenna 1 peduncle article 1 0.8 rest of article’s length; article 3 0.9 article 2 length; main flagellum 1.25 article 3 length; accessory flagellum with 1 article; aesthetascs 0.75 main flagellum length (Fig. 20 C). — Maxilliped 3 basis 0.84 rest of article’s length, with 3 plumose setae; ischium with 2 teeth; merus, 2 carpus length, with 6 short setae interspersed with short teeth on medial margin, 2 spines and 1 pappose seta; carpus 0.5 merus length, with 1 pappose seta; propodus 1.4 carpus length, with 1 lateral simple and 3 pappose setae; dactylus 0.58 propodus length, with 4 long terminal simple setae; with exopod (Fig. 20 D). — Pereopod 1 basis 0.8 rest of article’s length, with 2 pappose setae; ischium with 1 ppaose seta; merus 1.15 ischium length, with 5 pappose setae; carpus 1.13 merus length, with 6 pappose setae; propodus 2.5 carpus length, with 5 pappose setae; dactylus 0.4 propodus length, with 4 terminal simple setae; with exopod (Fig. 20 E). — Pereopod 2 0.33 rest of article’s length; merus 2.3 ischium length, with 2 plumose setae; carpus 1.76 merus length, with 3 plumose and 3 simple setae; dactylus 4 propodus length, with 8 simple setae and digitiform tip; with exopod (Fig. 20 F). — Pereopods 3–4 with decreasing basis and increasing carpus length; short dactylus with a long terminal seta (Fig. 20 G, H). — Pereopod 5 basis 0.6 rest of article’s length; merus 1.5 ischium length; ischium and merus with 1 simple seta; carpus 1.6 merus length, with 1 simple and 1 annulate seta; propodus 0.4 carpus length with 1 annulate seta; dactylus 0.6 propodus length, with terminal simple seta (Fig. 20 I). — Uropod peduncle 2.16 pleonite 6 length, serrate medially, 2.4 exopod length; exopod 1.08 endopod length, with 1 simple subterminal and 1 microserrate seta, 1 terminal microserrate seta 0.7 exopod length; endopod with 4 simple setae and 1 microserrate seta medially, 1 terminal microserrate robust seta 0.8 endopod length (Fig. 20 J).   
 Remarks. Campylaspis lowryi sp. nov. is closely related to C. radui sp. nov., having a similar circular sulcus on carapace. It differs in having an eyelobe with lenses, the maxilliped 3 merus longer than the carpus, the pereopod 2 dactylus with a pedunculate tip, and the uropodal endopod with 5 medial setae instead of 4 in C. radui sp. nov.   
 Distribution. Australia: WA—North West Shelf, at 43–44 m depth.
