Two specimens — the largest a female 25 millim. long — from off the 

 Travancore coast, 430 fathoms. 



The eggs are of enormous size, being nearly 2 millim. in major diameter after 

 contraction in spirit. 



The difference between Munidopsis Hemingi and M. ornata, Faxon, is very 

 slight ; in the latter species the edges of the rostrum are serrate and the 

 chelipeds and legs are armed with some spines.

Body pubescent ; thoracic legs densely covered with long hairs. Epipodites 

 as large as those of the external maxillipeds are present on the chelipeds. 



The greatest breadth of the carapace is about three-fourths the greatest 

 length. The rostrum, which is styliform, gently ascendant, and slightly curved 

 at tip, is a little more than half the length of the carapace ; the front margin 

 of the carapace is markedly oblique and is unarmed, except for a small antero- 

 lateral spine ; the lateral margins are parallel, with a slight convergence in the 

 anterior third, where there are two spinelets behind the antero-lateral spine ; 

 the posterior margin is raised and bears four strong spines in its middle third ; 

 the general surface of the carapace is smooth and polished anteriorly, and is 

 marked posteriorly by slight tranverse ripples. 



The anterior abdominal terga have a faint naked transverse groove, the 

 edges of which are quite smooth. 



The eyestalks, which are slender and comparatively long, are not prolonged 

 beyond the globular eyes, are not united, and are freely movable. 



The inflated basal joint of the antennulary peduncle has only one of its 

 spines, namely, that at the antero-external angle, long. 



The antennal flagellum is not much longer than the chelipeds (in the 

 female). 



The ischiopodite of the external maxillipeds has the inner edge evenly 

 toothed and the lower edge prolonged distally into a huge spine, while the 

 meropodite has two strong spines on the lower edge in the proximal half. 



The thoracic legs, except the fifth pair, are thickly covered with long hairs. 

 The chelipeds are long, slender, and slightly asymmetrical, the longer one 

 exceeding the length of the fully extended body (with the rostrum) by the 

 extent of the dactylopodite ; their ischiopodite has two strong distal spines, one 

 above, the other below, their meropodite two rows of spines along the upper
