2 Mr. Monracu’s Description of several new or rare Animals, 
more orless margined with long hair: tail small, nearly cylin- 
dric, the extreme joint acutely pointed. Diameter above one 
inch and a quarter. | 
Several of these crabs were taken in deep water by the trawl, 
all of which are evidently males; they were when fresh, though 
not alive, of a pale colour clouded with light ferruginous. 
Itis probably an inhabitant only of the dico! and difficult to be 
obtained, I having in no other instance been able to procure it.

in Gmelin in the division to which it belongs can be referred to.

Thorax ovate, gibbous, the front armed with two very long 
spines that form the proboscis; these are very close together, 
declining a little, and diverging at the points: over each eye 
is a short and broad spine, and two smaller immediately be-

top of the thorax are not easily defined, but along the middle is 
an undulated ridge running to an obtuse spine at the posterior 
. end : antenne shorter than the proboscis : arms slender, and not 
so long as the anterior legs, destitute of spines, but tuberous 
about ‘the joints; the fangs small and denticulated : legs eight : 
claws subulate, slightly hooked, and furnished beneath with mi- 
nute denticles : tail small, obtusely pointed. - 
The shell of this crab is livid white, but is most]: y concealed 
by a thick covering of short curled hair of a yellowish brown 
colour, the tips of the claws excepted: when this is removed, 
the shell appears under a lens full of punctures. Length an inch 
and a quarter, breadth three quarters of an inch.
