above dark purplish brown, with small markings of very pale 
bluish green. Carapace mottled and washed with pale dirty 
green, dark reddish brown, and straw-colour, with a few 
orange dots.” This specimen, in its dried state, is of a nearly 
uniform dull chestnut-brown. 
M. Brocchi (Ann. Sci. Nat. sér. 6, Zool. 11. p. 80, pl. xix. 
figs. 168-170, 1875) figures the male genital appendages of 
specimens both of this species and of P. Say? from Guade- 
loupe. In the specimens referred by this author to P. depressa 
the first pair of genital appendages are of peculiar shape, 
constricted in their subterminal half, and with the distal 
extremity of an oval form (fig. 170) ; whereas in male indivi- 
duals I have examined this pair of appendages scarcely differ 
in form from those of P. squamosa ; that is to say, they are, as 
in the Atlantic species, strongly contorted and truncated at 
the extremity.

This species is distinguished from all its congeners by having 
only three teeth upon the antero-lateral margins of the cara- 
pace, including the outer orbital tooth.

Only a carapace of this species is known. The disposition 
of the tubercles on the dorsal surface, as described by Dana, 
differs somewhat from that usual in P. sguamosa.

Is described by Dana as having the carapace smooth and 
glabrous, antero-lateral margin quadridentate, front above ob- 
liquely subcristate, not spinigerous. Anterior legs of male 
very short, part of hand preceding fingers shorter than its 
height, granulate above, smooth externally and not costate ; 
wrist nearly smooth. Third joint of eight posterior legs 
smooth. Third joint of outer maxillipeds quadrate, slightly 
oblong. 
Hab. New South Wales (Dana), Australia (coll. Brit. 
Mus.). 
The male specimen described by Dana measured about 9 
lines. The specimen in the British-Museum collection is a 
female of much larger size (1 inch 7 lines), and is closely
