CARCINOLOGICAL STUDIES. 243 



transverse gastrocardiac suture, are cristate and minu- 

 tely denticulate ; they present at some distance from the 

 external angles of the orbits a very small epibrauchial 

 tooth , which is however often only indicated by a trian- 

 gular and small incision of the margin. The antero-lateral 

 regions of the upper surface of the carapace are perfectly 

 smooth, presenting no wrinkles at all. The postero-lateral 

 margins , straight or a little convex and scarcely longer 

 than the antero-lateral ones , are covered with some rather 

 long , oblique wrinkles , which , as ordinarily , pass forwards 

 and downwards on the inflected portions of the carapace , 

 and the pterygostomian regions are also wrinkled. 



The impressed line on the punctate ischium-joint of the 

 outer foot-jaws lies not far from the internal margin and 

 not in the middle of the joint. Sternum and abdomen are 

 very finely , and not closely punctate. The lateral margins 

 of the abdomen of the male are a little concave. The pen- 

 ultimate joint is broader than long, and in the 

 middle of its length it is just once and a half 

 as broad as long; its lateral margins are very slightly 

 concave. The terminal joint is somewhat shorter than the 

 breadth of its posterior margin and nearly as long as the 

 penultimate joint. 



According to Milne Edwards' description , the anterior 

 legs of the male should be unequal and strong; they 

 are also unequal in the type-specimen of transversa. 

 Unfortunately I have not noticed how they are in the 

 adult male which I examined in Paris, but on the quoted 

 figure in the ))Nouvelles Archives" they appear rather fee- 

 ble and equal. I think that it represents the female or 

 that the figure is not correct. In our young male from Fidji 

 they are still equal and feeble. The fingers, which are so- 

 mewhat longer than the palm , meet almost completely 

 together, when closed, and are in our specimen longitu- 

 dinally grooved: two grooves are observed on the outer 

 side of the mobile finger, one or two also on the index. 

 The carpus , the upper surface of which is somewhat gra-
