194 ALLAN HANCOCK PACIFIC EXPEDITIONS • VOL.24 



Description: Carapace about one and a third times as long as broad, 

 convex front to back as well as transversely; covered with flattened 

 scalelike striations, larger and more distinct posterior to cervical groove ; 

 surface pubescent. Front distinctly tridentate, the teeth acute, approx- 

 imately equal in length and breadth, or median one slightly longer. 

 Outer orbital angle produced into a long, narrow, acute tooth. Epi- 

 branchial spine strong. 



Movable segments of antenna and flagellum less in their total 

 length than width of cornea of eye, or slightly longer than width of 

 eye; scarcely visible even under magnification. Outer maxillipeds lightly 

 rugose. 



Text-fig. 8. Basal segment of right antennule of Minyocerus kirki, x 38. 



Chelipeds short, stout, lightly rugose. Merus with two strong, for- 

 ward-pointing distal spines. Carpus with a similar, broad spine at about 

 center of anterior margin, often followed by several spinules, and usu- 

 ally with two or three strong spinules on distal margin; surface lightly 

 pubescent. Outer margin of manus with a finely granular crest, sur- 

 face covered with long scattered setae. Fingers short, tips blunt, meet- 

 ing for entire length or nearly so, dorsal surface and gape with long 

 scattered setae. 



Walking legs rather short and stout, all segments fringed with setae ; 

 merus obliquely rugose; carpus with two low longitudinal crests on 

 dorsal surface; propodus and dactylus smooth. 



Variations: The largest specimens examined, several of which were 

 of greater size than any seen by Glassell, have antennae with total 

 length somewhat greater than the width of the cornea of the eye, instead 

 of less than the corneal width as indicated in the type description. 

 There is considerable variation in the degree of spinulation on the 

 carpus and merus of the chelipeds.
