 TEXT CUT No. 8, var. caribcea. 



The rostrum is slender, compressed, acute, as seen from above, 

 a little longer than the orbital spines, which are wide at base, 

 acuminated and acute at tip, their margins being incurved. 



The antennular peduncle is rather slender ; proportions of the 

 segments are about 1.5: i.i : I ; its basal spine reaches about to 

 the middle of the second segment. 



The carpocerite is about three times as long as wide, and is 

 longer than the antennular peduncle by about the length of the 

 last segment of the latter. Its spine is nearly equally long, and 

 the scale is a little shorter and narrow. The basicerite has a short, 

 sharp lateral spine nearly as long as that of the antennules : above 

 it a smaller secondary acute spine. 



The large chela is oblong-ellipsoidal, only a little swollen in the 

 middle, and has a very small obtuse tubercle on its distal dorsal 

 margin. The width to the length of the palm is about as i : 1.90; 

 to the total length as I : 3.3. The carpus is very short and wide, 

 prolonged downward and inward. The merus is stout, width to 

 length as I : 2.3 ; its inferior distal margin ends in a sharp angular 

 point. 



The smaller chela is similar in form; breadth to length about 

 as i : 3.2 ; its fingers are pointed. The carpus is short cup-shaped ; 

 the merus, like that of the large chela, ends in a sharp distal point. 

 The legs of the second pair are slender ; first joint of the carpus 

 is equal to the remaining four ; chela is elongated, hardly thicker 

 than fifth joint of the carpus. 



The dactyl of the third pair of legs is elongated, tapered, and 

 a little curved on the outer side, less so on the inner side ; width 

 to length from 1:3.14 to 1:3.55. The hooks are unequal, the 

 outer one being thinner and a little longer, regularly curved, sharp ; 

 the inner is wider, strongly divergent and curved inward ; a short
