52 Transactions.—Zoology. 
The cephalothorax is oval, sides abrupt, roundly truncated in front; 
lateral marginal constrictions at the caput slight ; it is of a light yellowish- 
brown colour, sparingly clothed with light and dark hairs; from the hind- 
central eyes a lanceolate brown mark, with a light medial streak, extends 
to the base of the cephalothorax ; on either side there are broad brown 
marginal bands. The profile line rises abruptly from the thoracic junction, 
then runs in a nearly even line to the ocular area. The height of the clypeus 
exceeds the space between the eyes of the second row, and its direction 
nearly vertical. 
The four posterior eyes are equal in size, and form a moderately re- 
eurved transverse row ; the other four form a trapezoid whose shortest side 
is before, the posterior pair of the trapezoid are the largest, and the anterior 
pair much the smallest of the eight. 
The legs are moderately long and slender, and do not differ greatly in 
length, 1, 2, 4, 3, second and fourth nearly equal; they are like the 
cephalothorax in colour, and are marked with longitudinal streaks; the 
armature consists of hairs and long black spines. 
The palpi resemble the legs in colour and armature. 
The falces are subcylindrical, slightly inclined towards the lip, glossy, 
clear pale brown ; dark brown streaks, apparently a continuation of those 
on the frontal margin, extend along their entire length. 
The mazill are long, somewhat enlarged and incurved at their extremity ; 
a shade darker than the falces, tinged on the outer side with brown. 
The labium is a long oval, dark brown. 
Sternum broad, cordate, convex, reddish brown. 
The abdomen is oviform, rises abruptly from the petiolum, which is 
rather exposed ; its colour and markings resemble the cephalothorax ; a 
light, broad, tapering mark extends from the base to the spinnerets, in the 
centre there is an acute mark, formed by two dark streaks—in many 
examples, both male and female, the lanceolate marks are partly obliterated 
by whitish hairs—the lateral margins are dark brown, with a few light 
oblique streaks. Ventral surface light brown. 
The vulva is a simple greenish-brown lobe, with two brownish spots at 
the orifice. 
The male nearly equals the female in length, and does not differ essen- 
tially from her in form or colour. The superior claws of the tarsi are finely 
curved, and have about 18-20 parallel comb-teeth; the inferior claw ter- 
minates in a long fine, rather straight point, and has three long curved 
teeth. . 
The palpi are moderately long, the radial joint is blackish brown, rather 
stouter than the cubital, and projects a concave apophysis on the outer
