ing the first, and the third pair is the shortest; each tarsus is 
terminated by two curved, pectinated claws ; the palpi are short, 
and have a curved, pectinated claw at their extremity. The co- 
lour of these parts is pale dull-yellow, the sternum being the 
palest ; there is a minute brown spot near the base of the falces, 
in front, and their extremity is whitish ; two small black spots 
occur on the under side of the femora of the first pair of legs, 
one near the base and the other near the extremity, and there is 
a black transverse streak, which does not form an annulus, at 
the extremity of the genual, tibial, and metatarsal joints of each 
leg. 
Only one specimen of this pretty Thomisus was included in 
the collection.

Genus Sparassus, Walck. 
Sparassus abnormis, i. sp. 
Leen of an immature female 54- of an inch; length of 
the cephalothorax 4 3, breadth $; breadth of the didenan oa 
length of a leg of the second aie 2; length of a leg of the third 
pair 3. 
The legs are slender, provided with hairs and long spines, 
and are of a brownish-yellow hue; there are two minute black 
spots on the upper surface of the tibize, three on the metatarsi 
of the first and second pairs, and two on the metatarsi of the 
third and fourth pairs ; the second pair is the longest, then the 
first, and the third pair is the shortest; each tarsus is term1- 
nated by a single slender, curved, pectinated claw, below which 
there is a small scopula. ‘The eyes are seated on black spots, 
and are disposed on the anterior part of the cephalothorax in 
two transverse rows; the four anterior ones, which are the 
largest, form a straight row, situated near the frontal margin, 
and the other four constitute the posterior row, which is rather 
the longer and shghtly curved, having its convexity directed 
backwards. The cephalothorax is compressed before, truncated 
in front, greatly rounded on the sides, convex in the middle, 
sloped to each extremity, with a narrow longitudinal indentation 
in the medial line of the posterior region, and is of a yellow- 
brown colour, the lateral margins being much the palest. The 
falces are powerful, conical, vertical, and armed with teeth on
