Differs from Pagurus in the following particulars : — 



The chelipeds and next two pairs of legs are very regularly scutulated 

 transversely like a sort of ringmail, the free edge of the scutes being elegantly 

 ciliated. 



The chelipeds are equal and similar, or very nearly so, and the fingers of 

 both hands are short, blunt, and deeply spooned. 



In the female the abdominal appendages are biramous, not triramous 

 [and in the typical species {A. aniculus) in addition to the large foliaceous 

 brood-flap, each of the first three appendages carries a large leaf-like bract 

 which aids in forming the brood-pouch ). 



This small genus belongs to the Indo-Pacific, the species being found 

 from East Africa to Panama. 



Key to the Indian species of the genus Aniculus. 



I. Carapace not depressed, much longer than broad : — 



A. Eyestalks shorter than anterior border of carapace: frontal 



region, chelipeds, and legs remarkably hirsute ^ _ ^. aniculus, 



B. Eyestalks longer than anterior border of carapace : not strik- 



ingly hirsute ~. — — -^ A. tenehrariim. 



II. Carapace flat as a pancake: its greatest breadth exceeds its 



length ...„ — _ — ... A. strigatus.
