Carapace remarkably elongate, its greatest breadth hardly more than 

 half its length in the middle line. The region in front of the cervical groove 

 is very long, and its lateral borders are fringed wich tufts of long stiff yellow 

 and brown bristles. Similar bristles extend along the proximal half of the 

 eyestalks, and the peduncles of both pairs of antennae, and thickly beset 

 the antennal acicle. Rostrum not more prominent than the antennal angles 

 of the carapace. 



Eyestalks slender, longer than the antennular peduncles, much longer 

 than the anterior border of the carapace : eyes small : ophthalmic scales 

 rather large, spinose, approximated. 



Antennal acicle stout, a little overlapping the base of the terminal joint 

 of the peduncle : antennal flagellum stout, about as long as the carapace. 



Chelipeds subequal, about as long as the carapace ; they and the legs 

 remarkably hirsute : their merus is compressed and nearly as high as long, its 

 sharp upper border and its lower surface hirsute in tufts, its inner lower border 

 serrated: the extensor surface of the wrist, hand, and fingers is beset with 

 conical tubercles or stout spines, from each of which springs a tuft of stiff 

 yellow or brown bristles : the hands are short, broad, and globous inferiorly : 

 the fingers are short and very broad. The 2nd and 3rd pairs of legs are 

 thickly beset with tufts of yellow and brown bristles, which are long and 

 stiffen the edges of the joints. The 2nd pair exceed the chelipeds by their 

 dactylus and more than half their propodite, which latter joint is considerably 

 longer than the dactylus. The 3rd pair are not quite so long as the and pair, 

 and their propodite is only slightly longer than their dactylus. The propo- 

 dite of the 3rd left leg has its outer surface sharply flattened and thickly 

 hirsute. 



Colours in spirit : anterior half of carapace, eyestalks, antennal peduncles, 

 chelipeds and legs dark crimson, the chelipeds and legs profusely and con- 

 spicuously, the carapace very finely and inconspicuously maculated with 

 yellow : the cardiac region and its vicinity are usually stained with red and 

 finely spotted. 



Length of carapace 28 millim.
