discussion
Remarks. Schultz (1966) stated that his type was a female but labelled his figure 10 of the fused penes as ‘ first male pleopods’. The specimen is clearly a male; a female could be expected to have a wider midpereon. His dorsal habitus figure is reproduced here along with new illustrations of pereopod 2, pleopods 1 and 2, and the uropod, not figured in the original description. b d e

Material examined. Holotype. USA, California, Tanner Canyon, 32 ° 33 ’ 36 ” N, 118 ° 55 ’ 40 ” W, 1298 m, green mud, 28 Jan 1960 (Velero IV stn 6832), LACM Cr 19600802 (male, 5.5 mm). [LACM label states: 236 ° from China Pt Light, San Clemente I., Channel Is, CA, 32 ° 31 ’ 15 ” N, 118 ° 54 ’ 02 ” W, 1320 m, Velero IV, 29 Jan 1960]. Supplementary redescription. Pereopod 2 carpus twice as long as merus, convex along flexor margin; propodus as long a carpus, almost linear; dactylus with unguis 0.7 length of dactylus body; ischium – carpus each with few marginal and submarginal setae, propodus with 4 mesial facial setae, dactylus with 1 strong mesial facial seta. Pereopods 3 and 4 similar, slightly shorter. Male pleopod 1 exopod ending in rounded setose lobe; posterior groove ending in deep fissure about 0.7 along length formed by a lateral lobe and a curved secondary lobe mesially; exopod 0.7 times length of endopod. Pleopod 2 endopod slightly longer than exopod; appendix masculina slightly curved, slightly longer than endopod, covered with fine setae. Pleopods 3 – 5 without marginal long setae. Uropodal endopod broader than long, with subdistal stout seta; exopod narrower than endopod, tapering, with longer distal stout seta.
