Two male specimens were collected at Elphinstone Island. 

 They agree very well with the original description, but the 

 upper and external surface of the bands is not a little granular, 

 but only rugose, and the penultimate joint of the abdomen in 

 both individuals is quadrate, as long as broad, and resembles that 

 of Carpilodes venosus, Milne-Edw. ; while in New-Caledonian 

 specimens, according to the figure given by A. Milne-Edwards, 

 this joint is a little broader than long. 



The cephalothorax of the larger specimen is 13| millim. broad 

 and 8 millim. long. 



This species is most closely allied to Carpilodes venosus, 

 M.-Edw. (= Carpilodes ohtusus, de Haan), for the latter appears to 

 be only distinguished by the upper surface of the carapace and 

 of the hands being wholly smooth, 



Carpilodes Stinipsoni has hitherto been only recorded from the 

 shores of New Caledonia.

One male specimen was collected at Elphinstone Island. 



Though doubtless belonging to this species, it presents 

 nevertheless two slight differences from Dana's figure which 

 are worthy of notice, as being probably caused by the fact that 

 this specimen had not yet attained its full size. The front 

 projects a little more forward, and the most internal lobule of 

 the protogastric lobe (areola 2 M), which is adjacent to the meso- 

 gastric lobe, is scarcely broader than the latter, while this lobule 

 in Dana's figure appears nearly twice as large as the mesogastric 

 lobe. 



The cephalothorax of this specimen is 13f millim. broad and
