286 MR. BELL, HORZ CARCINOLOGICE ; 
lated, latero-anterior portion slightly waved, posterior margin a little projecting. Thoracic 
sinus deep, very narrow, terminating anteriorly in a narrow double notch, which is fur- 
nished beneath with a few large granulations. External pedipalps in the male quite 
smooth; in the female the stalk has the basal half much raised; the inner edge hairy. 
Anterior legs rather longer than the carapace; the arm granulated above, excepting the 
anterior tubercle; wrist smooth; hand longer than broad, carinated on each side, wholly 
without granulations, fingers meeting only at the points, without teeth or tubercles, the 
fifth pair with the penultimate joint as broad as it is long. Abdomen in the male with 
two rounded smooth elevations at the base, narrowest towards the centre; in the female 
broad oval, widened towards the anterior part. 
Length of the carapace 0:9 in. : 
Colour rich brown above, the two posterior spots darker; light brown beneath. 
Several specimens in the British Museum and in my own collection were brought from 
the Philippines by Mr. Cuming.

Carapace longer than broad by the whole length of the front, somewhat narrowed for- 
wards, the latero-anterior margin nearly straight; hepatic region with a slight elevation ; 
thoracic sinus deep, extending forwards very little in advance of the insertion of the ante- 
rior feet, and bounded by a semicircular granulated margin. Marginal granulations of 
the carapace extremely small and not contiguous at the anterior part, gradually enlarging 
and becoming flattened backwards. Front minutely tridentate, the middle tooth the 
longest. External foot-jaws smooth, polished, with a line of minute impressed dots near 
the margin. Anterior legs robust ; arm on the upper side with a line of large granulations 
on the outer and inner margins, a few on the proximal portion, and two or three only 
extending forwards, the rest of the upper surface smooth ; the under side with a line of 
similar granulations on the inner margin. Wrist smooth, rounded, with a line of minute 
granulations on the inner side; hand rather longer than broad, somewhat tumid in the 
middle, flattened towards the edges, the inner edge with a line of small granulations, the 
outer smooth and rounded; fingers meeting only at their points, armed with distant 
tubercles, and having a wide space near the joint. Abdomen (male) broad at the base, 
then with the sides parallel, the penultimate segment rounded at the anterior margin, and 
armed with a strong straight pointed tooth.
