CBUSTACEA OF THE MER&FI ARCHIPELAGO. 219 



The upper surface of the carapace is smooth, though sparsely 

 punctate. The front is rather broad, with a straight, truncate, 

 anterior margin. The external orbital angle is acute, and there 

 is no epibranchial tooth. The anterior half of the lateral 

 margins is cristate, but the posterior is rounded and covered with 

 some oblique elevated lines. The chelipedes are unequal, the 

 left being the larger. The carpopodite is scarcely longer than 

 broad, and is armed at its anterior margin with two or three acute 

 teeth ; the upper surface is somewhat uneven, presenting some 

 oblique elevations, especially towards the posterior (external) 

 margin. The outer surface of the hands bears three or four 

 somewhat uneven longitudinal ridges, by which two or three 

 longitudinal grooves are formed. The upper surface of the car- 

 popodite and the outer surface of the hand are glabrous, but 

 distinctly punctate. The fingers have somewhat curved, acute 

 tips. The inner surfaces of the hands are very convex and also 

 somewhat punctate. 



The meropodites of the ambulatory legs are unarmed. The 

 somewhat hairy carpopodites and propodites are longitudinally 

 sulcate on their upper margins, and the acute dactylopodites 

 are armed with two or three short spines on their inner 

 margins.

The specimen perfectly agrees with the description of P. pul- 

 cJiella, Hasw. Mr. Haswell erred in separating his specimens 

 as a distinct species from P. sculpta, M.-Edw,, in which the 

 anterior margin of the wrist of the chelipedes is armed with two 

 strong teeth, as in P. puchella. 



P. sculpta, Dana, however, is probably another species, as the 

 anterior margin of the wrist seems to be unarmed. 



Forcellana sculpta, M.-Edw., has been observed on the coasts 

 of Java and of Northern and North-eastern Australia.
