88 CARCINOLOGICAL STUDIES. 



the length of the cephalothorax. The palm is once and a 

 half as long as the horizontal length of the fingers and 

 as long as high; the outer surface is convex and per- 

 fectly smooth, presenting only a faint longitudinal line 

 on the lower part , which proceeds somewhat obliquely 

 from the articulation of the wrist to the tip of the im- 

 mobile finger. The upper surface ofthepalmis margined 

 above and the inner surface presents a few oblique rugose 

 lines immediately below that margin. The upper margin of 

 the dactylus is somewhat rugose at the base , for the rest 

 the fingers are quite smooth ; their tips are excavated 

 and the inner margins feebly denticulated. Mucli smaller 

 are the hands of the female, measuring only about two 

 thirds of the length of the carapace; the fingers are as 

 long as the palm and the latter is marked with some obli- 

 que rugose lines below near the articulation of the wrist. 

 The ambulatory legs are short and stout. The meropo- 

 dites of the last pair of legs have the distal 

 angle of their inferior margin rounded; those 

 of the penultimate pair present slight traces of two or three 

 teeth ; these small teeth , finally, are rather distinct at the 

 distal angle of the inferior margin of the meropodites of 

 the two anterior pairs. I may add that the meropodite of 

 the right leg of the last pair in our male specimen shows 

 faint traces of two teeth, which I have figured, whereas 

 this limb is rounded on the left side. The dactylopodites 

 are short , stout and spiniferous. The legs are nearly gla- 

 brous , only a few rows of short hairs being observed on 

 the upper and lower surfaces of the carpopodites and pro- 

 podites. The upper surface of the carapace is marked , on 

 a violet-reddish ground-colour , with yellowish spots and 

 lines , especially on the branchial , mesogastric , cardiac and 

 intestinal regions. The anterior legs present a reddish ground- 

 colour above , and are marked with yellow ; the hands have 

 a yellow outer surface, showing reddish reticulate lines on 

 its upper part. The ambulatory legs present yellow mar- 

 kings on a reddish-violet ground-colour.
