21. Paratelphusa (Barytelphusa) falcidigitis, Alcock. (Fig. 24.) 



This " species " I believe to be a variety of lugubris. 



It resembles the variety plauta in having the carapace very decidedly flat 

 (with even the individual regions hardly tumid), and not quite so broad as in 

 the type of luguhris, and the Avings of the cervical groove broader and a trifle 

 more superficial. 



Beyond this it difiers from the type of lugubris only in the foUovping 

 particulars : — 



The lateral epibranchial tooth is smaller and smoother ; it is sometimes 

 oljsolete. 



The post-orbital crests are sharper. 



In the male abdomen the 6th segment is, as in old individuals of harpax, 

 longer, its length being nearly equal to its proximal breadth and exceeding its 

 distal breadth. 



The chelipeds have their surface sculpture even more effaced-looking, so 

 that, though they are not smooth, they have a sort of " smoothed " look ; they 

 are not so unequal, the smaller cheliped being larger in proportion than in 

 lugubris. They have the fingers very remarkably broadened, so that, although 

 the dactylus is very strongly curved along the upper l)order, the fingers, when 

 closed, are in contact, or almost so, along their whole cutting edge. Sometimes 

 there is a row of two or three spines, or lai-ge bead-like granules, on the base of 

 the upper sm'face of the dactylus. 



The legs are remarkable for the peculiarly strong spines of the edges of the 

 dactyli, and for the very sharply and prominently serrated edges of the 

 propodites. 



In the largest specimen, a female, the carapace is 21 inches long, 2i| 

 inches l»road, and 1 inch deep.
