Two male specimens were collected at Elpbiustone Island. 
They agree very well with the original description, but the 
upper and external surface of the hands is not a little granular, 
but only rugose, and the penultimate jomt 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 obtusus, 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 Stimpsoni has hitherto been only recorded from the 
shores of New Caledonia. 
Genus Acrma, de Haan.

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 132 millim. broad aud
