19. Paratelphusa (Barytelphusa) lugubris, var. nigerrima, Alcock. 



In this variety the carapace is not quite so broad as it is in many males 

 of the typical form, and the lateral epil^ranchial tooth, though by no means 

 spine-like, is more prominent. The cervical groove is deeper cut, and so the 

 individual regions of the carapace look more convex. The antero- lateral 

 borders of the carapace are slightly less convex. Its colour is darker, being 

 greenish black or almost coal black (in spirit). 



In the largest female the carapace is If inch long, 2fV inches broad, and 



fths inch deep.

(Fig. 23.) 



This variety agrees with the type in every particular except the following : — 

 The carapace is particularly flat (even the individual regions, the gastric 



excepted, are flat) and is not quite so broad as in the type, and its antero-lateral 



borders are slightly less convex. 



The wings of the cervical groove are broader and more superficial.
