410 REV. O. P. CAMBRIDGE ON NEW DRASSIDES. [June 2, 



luteous yellow colour, with a slight indication of the ordinary elon- 

 gate macula on the fore half of the upperside. The spinners are not 

 large; those of the superior pair are two-jointed,- the second joint 

 being small and shorter than the first. The adult female resembles 

 the male in colours and general characters ; the genital aperture is 

 small and of a narrow transverse kidney-shape. 



The colour of the abdomen in this and many other very similarly 

 coloured species can hardly be reliable as above described, the speci- 

 mens having been some time preserved in spirits of wine ; in our 

 indigenous British species the colours of the abdomen are in life more 

 or less green, while the spirit discharges this in a short time, leaving 

 it only of a dull yellow ; and this is very probably the case in the 

 present and many other exotic species of this same genus. 



An adult male and female of this remarkable and easily distin- 

 guished Spider were contained in the Bombay collection received 

 from Major Julian Hobson ; and the collections received from Ceylon 

 from Mr. G. H. K. Thwaites also contained many adult examples of 

 both sexes. 



Cheiracanthium vorax, sp. n. (Plate LII. fig. 33.) 



Adult male, length 3| lines ; adult female 5 lines. 



The whole of the fore part of this species (except the falces, which 

 are of a deep rich reddish brown, the ocular region, the maxillae, 

 and labium, which are suffused with reddish brown) is yellow; the 

 cephalothorax is (looked at from above) short and broad, round 

 behind, constricted laterally at the caput, broad and truncate at the 

 eyes ; the normal lateral grooves and indentations are indicated by 

 dusky yellow converging streaks ; the profile of the cephalothorax 

 is curved, sloping quickly from the middle of the caput to the frontal 

 m argin or lower edge of the clypeus ; the hinder slope is gradual and 

 also curved; it is pretty fairly clothed with fine, rather short, pale 

 hairs. The clypeus is very low, being less in height than the diameter 

 of one of the fore central pair of eyes. 



The eyes are in two almost equally curved transverse rows of very 

 nearly equal length ; the front row is the straightest, and the curves 

 are directed away from each other ; those of the fore central pair are 

 the largest of the eight, and are rather nearer together than each is 

 to the fore lateral eye nearest to it ; and this is also the case in regard 

 to the eyes of the hind central pair ; these with the fore centrals 

 form very nearly a square, whose transverse diameter, however, is a 

 little longer than its longitudinal ; those of each lateral pair are 

 seated slightly obliquely on a small tubercle, and are very near to 

 each other, but not contiguous. 



The legs are long, moderately strong ; their relative length is 1, 

 4, 2, 3 ; they are furnished with fine hairs and a very few spines, 

 those on the tibial and metatarsi of the fourth pair being the most 

 numerous and arranged somewhat in rings ; the tarsi terminate with 

 the usual two claws, beneath which is a compact scopula of black 

 hairs. 



The palpi are rather slender and not very long ; the radial is full
