 Achceopsis Giintheri, sp. n. (PL IV. fig. 1.) 



Carapace broadly triangulate, moderately convex. Ros- 

 trum short, spines acute. There is a small supraocular spine. 

 The spines of the carapace are disposed as follows : — There is 

 a very large perpendicular spine upon the gastric region, a 

 large blunt conical tubercle upon the cardiac, and a smaller 

 tubercle upon each of the branchial regions. The postocular 

 spine is small. Behind the eyes, on the subhepatic region, is 

 a blunt tubercular prominence. The anterior legs (in the 

 female) are small. The ambulatory legs are smooth, of 

 moderate length ; the terminal joints in the first pair long, 

 slender, and nearly straight ; in the following pairs slightly 

 curved. Length to base of rostrum ^ inch. 



Hah. Cape of Good Hope (H.M.8. 'Herald'). 



A single adult female is in the collection. Length of cara- 

 pace about \ inch. 



This species is easily distinguished by the remarkably pro- 

 minent gastric spine. The terminal joints of the legs and the 

 carapace in front of the gastric spine are slightly hairy. In
