10(3 A. Alcock — Carcinological Fauna of India, [No. 1, 



In the Indian Museum is a specimen from Port Blair Harbour 

 (Andamnns), and one from the Angrias Bank (Malabar Coast) in 



15 fms. 



Although the chelipeds and antero-lateral margins make this 

 species easily recognizable from Lophozozyrnus incisus (Edw.) de Man, I 

 am inclined to suspect that this is the young of L. incisus.

Lophozozyrnus, Miers, Challenger Brachyura, p. 114. 



Differs from Zozymus in having (1) the crest of the anterolateral 

 border sharp-edged and (2) the fingers not spooned at tip. To avoid 

 unnecessary disturbance of accepted nomenclature the name is here 

 maintained as a subgenus of Zozymus. 



Key to the Indian species of the subgenus Lophozozyrnus. 



I. Front lobe of the antero-lateral border confluent and 

 fused with the orbit : [size moderate or small]: — 



. Regions and lobules of carapace well defined ; the 

 lobules pitted or dented, the grooves between 



them hairy : chelipeds and legs shaggy L. incisus. 



i. Regions and lobules of carapace ill denned and 

 faint : surface of carapace smooth and bare : legs 



with a few lank scattered hairs L. dodone. 



II. Front lobe of antero-lateral border separated from the 

 orbit by a gap; carapace smooth, the regions (but not 

 the snbregions) fairly well defined : [size large]: — 



i. Hands smooth and bare L. octodentatus. 



ii. Outer surface of hand granular and hairy L, cristatus.
