armed with teeth on the inner surface ; the maxill are straight, 
enlarged at the extremity, which is rounded on the outer side 
and obliquely truncated on the inner side, where it is supplied 
with long hairs; the lip is short, broad, and somewhat quadrate, 
but rounded on the sides; the sternum has a broad oval form, 
with small eminences on the sides, opposite to the legs. These 
parts are of a dark-brown colour, the falces, which are much 
the darkest, being supplied with red hairs at the base, im front. 
The legs are long, robust, provided with brownish-yellow hairs 
and strong sessile spines, and are of a red-brown colour; the 
first pair is the longest, then the fourth, and the third pair is 
the shortest ; the metatarsi and tarsi have brown hair-like papille 
on their inferior surface, and the latter are terminated by two 
curved claws, pectinated at their base. The palpi are long 
and rather lighter- coloured than the legs, with the exception of 
the digital joint, which has a brown hue. The abdomen is-ovi- 
form, densely covered with brownish-yellow hairs, convex above, 
and projects a little over the base of the cephalothorax ; a series 
of broad, curved, angular lines of a brown coiour, having their 
convex sides towards each other and their vertices directed for- 
wards, extends along the middle of the upper part ; and on each 
side of it there is a row of four depressed dark-brown spots: 
the sexual organs, which are well developed, and of a red-brown 
colour, have a large process directed backwards from their an- 
terior margin, whose extremity is dilated. 
This large Ctenus was the only individual of the species in- 
cluded in the collection.

Lene of the female } of an inch; length of the cephalo- 
thorax =8;, breadth -2,; breadth of the abdomen ars length of 
an anterior leg 35 length of a leg of the third pair -2,. 
The abdomen is oviform, somewhat pointed at the spinners, 
very convex above, and projects over the base of the cephalo- 
thorax ; it is clothed with adpressed hairs, and is of a red-brown 
colour ‘mingled with yellowish white ; the under part, which is 
of a yellowish- white hue, has a dark-brown band extending 
along the middle; the [eal organs are moderately developed, 
with a longitudinal septum,in the middle; they are of a dark 
red-brown colour, the posterior margin being much the palest, 
and that of the branchial opercula is brown. The eyes are dis- 
posed on the anterior part of the cephalothorax, high above the 
frontal margin; the four posterior ones form a greatly curved 
transverse row, whose convexity is directed upwards and some- 
what backwards, and the other four describe a trapezoid whose
