The rostrum is subacute with a blunt tip, and varies con- 

 siderably in prominence. The lateral frontal processes are 

 shallow and not so long as the rostrum. The gastric area is 

 broad and convex from in front backwards, and from side to 

 side. It is strongly calcified. Behind the well-marked cervi- 

 cal groove the carapace is softer, but not so nearly membranous 

 as in Eupagurus. There are a few groups of setae on the hepatic 

 areas and many behind the cervical groove. 



The abdomen is long and rather slender, twisted in the usual 

 way. The telson is only slightly asymmetrical and is minutely 

 toothed on the posterior edges. 



The eyestalks are rather slender and taper very slightly in 

 a distal direction. They bear large numbers of setae on their 

 dorsal surface. The cornea is rather small, appears brown 

 (in spirit), and is slightly emarginate on the posterior dorsal 

 edge. The ophthalmic scales are small and spiniform. 



The antennular peduncle is very long and slender, which is 

 mainly due to the great development of the third joint. It 

 reaches when extended far beyond the antennal peduncle. 

 The cornea reaches slightly beyond the base of the second 

 joint. The upper flagellum is fully two-thirds as long as the 

 third peduncular joint. 



The external process of the second joint of the antennal 

 peduncle is short, not reaching the middle of the fourth joint. 

 The process bears a few teeth on its inner edge near the tip. 

 The acicle is almost cylindrical, thick, tapering suddenly to a 

 sharp point. It reaches just beyond the tip of the fifth joint, 

 and bears groups of setae on its inner edge. The third joint 

 is, as usual, nfiost easily seen from below and bears a small distal 

 tooth. The fourth joint is short and cylindrical. The fifth 

 is the longest of the series and is slightly compressed. Each 

 joint of the flagellum, which is about four and a half times as 

 long as the carapace, bears several setae.
