New and unusual abyssal gammaridean Amphipoda from the north-east Pacific Author Hendrycks, EA Author Conlan, KE text Journal of Natural History 2003 37 2303 2368 journal article 1464-5262 Rhachotropis distincta (Holmes, 1908) Gracilipes distincta Holmes, 1908: 529–531 , figure 35; Thorsteinson, 1941: 85 (key). Rhachotropis distincta : Shoemaker, 1930: 316–323 , figures 41–44; Stephensen, 1944: 18; Birstein and Vinogradov, 1955: 276; Birstein and Vinogradov, 1958: 248; Barnard and Karaman, 1991: 338; Bousfield and Hendrycks, 1995: 43–45, figures 29, 30. Material examined Juvenile W , 6.7 mm , (appendages on one slide), CMNC 2002-0036 , Sta. 1014, Cup # 9, 34°53.22∞N, 123°02.13∞W, 4050 m , 13 January 1992 . Remarks This small male shows some variation from that figured by Shoemaker (1930) from the Cabot Strait ( 378 m ) and Bousfield and Hendrycks (1995) from the Queen Charlotte Islands ( 0–1227 m ). These differences include a shorter rostrum, longer carpus on peraeopods 3 and 4, weaker spination on the posterior margin of the basis of peraeopod 4 and shorter uropod 3 rami. Otherwise the specimen agrees with the descriptions and figures of the above authors. Distribution North Pacific and north Atlantic in net tows from depths of 0–7000 m . This confirmed record of 4050 m is a new depth record as previous collections came from trawls where the capture depth was not verified.
