colour suffused with red-chestnut, the other joints are yellowish with brown 
annulations. The tarsi terminate with three claws all differing from the 
rest in strength and curvature. 
The palpi are short, with annulations of three shades. 
The falces are vertical, dull black, finely rugulose. 
The maville are somewhat quadrate, blackish-brown, reddish margins. 
The labium is triangular, about twice as long as high, resembles the 
maxille in colour. 
The sternum is blackish-brown, heart-shaped. 
The abdomen is iarge, on the fore part, which projeets over the base of 
the cephalothorax, there is an oblong brown mark, margined with a smooth 
space of a pinkish colour clothed with whitish hairs; on either side the 
surface of the anterior part of the abdomen is deeply wrinkled; four 
prominent humps form a transverse row across the centre, the exterior ones 
are somewhat conical, divergent, and directed slightly backwards; the 
upper and anterior face has an olive hue, the ridges tinted with brownish- 
pink; the posterior extremity is somewhat pointed with five transverse 
wrinkles ; the hind parts are tinted with light shades. The ventral surface 
has deep transverse wrinkles, is of a yellowish-brown colour, sparingly 
furnished with light hairs. The vulva is black with a large reddish lip-like 
protuberance,

Argyrodes conus, sp. n. Pl. x., fig. 6. 
Length of a mature female 23 mm., and of an adult male 2 mm, 
The cephalothorax is oval, moderately convex, glossy black; nearly 
glabrous ; the profile line ascends gradually from the thoracic junction in 
an undulating line, caused by the transverse indentation, to the ocular 
area ; the forepart of this area is very prominent, forming a deep indenta- 
tion in the profile of the clypeus, whose height otherwise is rather more than 
the length of the ocular area; lateral marginal constrictions at the caput 
moderate, normal grooyes deep. 
The eyes are about equal in size, and have a pearly lustre; the four 
central eyes form a square, and the hind-centrals are rather further apart 
from each other than each is from the posterior lateral eyes, which are 
seated obliquely on strong tubercles and nearly contiguous to the anterior 
laterals, ` 
The legs are long and slender, the first pair is the longest (6 mm.), 
y have yellowish-brown tints, and with 
the exception of the first pair, only faintly annulated with a darker hue ;
