130 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 24 



Description: Carapace usually a little broader than long (1.0 or 1.1 

 times in males, 1.2 or 1.3 in females), strongly convex front to back, 

 surface punctate, slightly uneven, devoid of hairs or at most v^^ith traces 

 visible only under magnification. Front rounded in dorsal view^, in 

 frontal view transversely sinuate or faintly trilobate. Orbits rather shal- 

 low. Side wall consisting only of a small anterior wedge, ending at 

 epibranchial level ; posterior membrane thickly covered with fine hairs. 



First movable segment of antenna with a strongly projecting tuber- 

 cle on anterior margin; second and third lightly granular; flagellum 

 with short hairs. Outer maxillipeds smooth or punctate, surface of 

 ischium with scattered hairs. 



Merus of chelipeds covered with flattened, scale-like granules; distal 

 end of anterior margin with a small granular lobe ; ventral surface 

 smooth. Carpus armed on anterior margin with four to six narrow, 

 rounded, well-separated teeth, some of them bifid at their tips, all 

 about equal in size ; surface evenly covered with large rough granules, 

 between the granules a short pubescence ; ventral surface smooth. Manus 

 and fingers covered with granules, larger than those of carpus, some- 

 what more projecting toward outer margin of manus and pollex; be- 

 tween the granules a short pubescence, as in carpus; ventral surface 

 with flattened granules, rougher toward outer margin of manus. Dac- 

 tylus of major cheliped with a row of three or four tubercles on cutting 

 edge, proximal one larger and more projecting than others ; pollex short, 

 conical, with a large tubercle on cutting edge ; fingers meeting at 

 tips, slightly gaping, gape with traces of hair. Dactylus of minor chel- 

 iped with a row of small tubercles on cutting edge; pollex short, con- 

 ical, with a row of small tubercles; fingers meeting for entire length, 

 gape with traces of hair. 



Walking legs punctate or lightly granular; fringed on anterior mar- 

 gins with plumose and non-plumose hairs. 



Abdomen smooth or punctate ; telson with five plates. No pleopods 

 in male. 



Measurements: Holotype male: length 4.2 mm, width 4.5 mm. Para- 

 types: males, 1.7 to 6.0 mm; non-ovigerous females, 1.9 to 2.3 mm; 

 ovigerous females, 2.1 to 5.2 mm. 



Color: The color in life was not recorded. In specimens preserved 

 only a few years in alcohol the carapace is orange, with a white spot 

 on the front, a narrow longitudinal white streak on the mesogastric 

 region, and an oblique white streak or a white spot on each meso- 

 branchial area. The chelipeds are orange, with the granules darker, and
