? Kraussia rastripes, F. Miiller, Verb. Ges, Basel. VIII. 1886, pp. 475, 480, pi. 

 iv. fig. 5. 



Carapace about four-fifths as long as broad, little convex, smooth 

 to the naked eye, but with fine transverse subsquamiform pitting under 

 the lens. 



Frontal, orbital, and antero-lateral borders elegantly uniformly and 

 conspicuously denticulate, and fringed (except the infra-orbital bor- 

 der) with long stiff silky hairs. Similar hairs fringe the legs, the 

 arm and the inner angle of the wrist, and the anterior edge of the 

 external maxillipeds. 



Front cut into two broad lobes, each of which shows a very slight 

 tendency to be divided into two lobules. Dorsal surface of roof of 

 orbit without any marked grooves. 



Chelipeds about as long as the carapace, the hand the most mas- 

 sive joint : the fingers are very short and stumpy, the dactylus closing 

 very obliquely on a short straight immobile finger that is little better 

 than a tubercle. On the outer surface of the hand is some fine sub- 

 squamiform sculpture : on the upper surface of the finger are some 

 bluntly- dentiform granules in rows, and there are some granules near 

 the inner angle of the wrist. 



Legs stoutish, slightly shorter and much less massive than the 

 chelipeds : the dorsad surfaces of the propodites and dactyli — as of the 

 carpopodites also in their distal end — are abundantly and elegantly 

 denticulate. All the dactyli are blade-like. 



In the Indian Museum are two specimens from the Andamans.

Differs from K. Integra in the following particulars : — 



(1) The length of the carapace is more than four-fifths the 

 breadth, and the carapace is more convex from side to side : 



(2) The frontal, orbital, and antero-lateral borders are minutely, 

 instead of conspicuously, denticulate, and the hairs that fringe them are 

 more scanty : 



(3 ) The front is more prominent and is cut into 2 lobes each of 

 which is deeply cut into 2 lobules : 



(4) There are two distinct though fine grooves in the roof of 

 the orbit, one of which passes far back on to the carapace and imitates a 

 cervical groove : 



( 5) The chelipeds are quite smooth except for a few granules at 

 the inner angle of the wrist :
