is not at all prominent. The antero-lateral margins are scarcely 
shorter than the postero-lateral and are armed behind the external 
angles of the orbits, which are not at all prominent, with four 
teeth, the anterior one of which is represented by a rather blunt, 
low, rounded prominence which is itself crenulate. The second 
resembles the first in being crenulate, but it terminates in a 
minute spine, and the two posterior teeth are distinctly spini- 
form. There is no trace of a subhepatic tooth or spine. The 
endostome is faintly ridged. 
The chelipedes and the other legs seem to resemble those of 
the specimens collected during the voyage of H.M.S. ‘ Alert.’ 
The left chelipede is much larger than the right and granular, 
some larger granules of the outer surface of the palm being 
arranged in longitudinal series. The hand of the smaller cheli- 
pede is very hairy externally. The small specimen is only 
7 willim. broad and scarcely 5 millim. long. 
- This species is somewhat allied to Pelumnus Dehaanit, Miers, 
from the Japanese seas, but P. seminudus has a more enlarged 
cephalothorax. Although Mliers’s specimen agrees very well 
with the description of P. seminudus, I would point out that 
the existence of fowr antero-lateral teeth has not been clearly 
indicated by the English carcinologist, and that the granules 
with which the anterior legs are covered are rather conspicuous. 
Pilumnus seminudus has been recorded from the eastern and 
north-eastern coasts of Australia (Port Denison, Torres Strait).

Two specimens (¢ 2), not yet full-grown, were collected at 
Sullivan Island. 
In this small species the carapace is broader than long, the 
proportion of the distance between the last antero-lateral teeth to 
the length of the cephalothorax (the basal portion of the abdo- 
men, as far as it is visible from above, excluded) being about as 
7to5. Theupper surface is a little convex and perfectly smooth; 
the regions are quite indistinct, there being no trace of divisional 
lines, except the usual longitudinal median furrow on the front, 
which separates the epigastric regions and the usual transverse 
cervical suture. The upper surface is, however, a little hairy, 
and presents three elevated transverse lines, which are clothed
