An immature male of this handsome spider, which has not 
hitherto been recorded as indigenous to Britain, was transmitted 
to me from Exeter, by Mr. Edward Parfitt, in August 1866. 
This specimen, which had not undergone its final ecdysis, was 
captured in Devonshire. 
Family Drassip2. 
Genus Drassus, Walck. 
Drassus Collingsia, n. sp. 
Length of an immature female (not including the spinners) 
=, of an inch; length of the cephalothorax +5, breadth +'; ; 
breadth of the abdomen +!, ; length of a posterior leg 2; length 
of a leg of the third pair 4. 
The eyes, which are seated on black spots, are disposed in 
two transverse, slightly curved rows, on the anterior part of the 
cephalothorax ; the posterior row is rather the longer, and the 
two intermediate eyes are nearer to each other than they are to 
the lateral eyes of the same row ; the intermediate eyes of the 
anterior row, which is situated immediately above the frontal 
margin, are the largest and darkest-coloured of the eight. The 
‘cephalothorax is convex, glossy, compressed before, rounded on 
the sides, which are marked with furrows converging towards a 
narrow indentation in the medial line of the posterior region, 
and is of a brownish-yellow colour, with narrow, soot-coloured 
lateral margins. The falces are conical, rather prominent, and 
have one or two small teeth on the inner surface; the maxille 
are convex near the base, depressed transversely near the mid- 
dle, enlarged at the extremity, and inclined towards the lip, 
which is somewhat quadrate, being rather longer than broad ; 
and the sternum is oval, with small eminences on the sides, 
opposite to the legs. These parts have a brownish-yellow hue, 
the lip being the brownest, and the sternum, which is the palest, 
having soot-coloured lateral margins. The legs are moderately 
long, hairy, and of a pale brownish-yellow colour; the inferior 
surface of the metatarsi and tarsi are clothed to a greater or 
less extent with greyish-brown hair-like papilla, and the tibie 
and metatarsi of the third and fourth pairs are provided with 
sessile spines; the fourth pair is the longest, then the first, and 
the third pair is the shortest; the tarsi are terminated by two 
curved, pectinated claws. The palpi resemble the legs in co- 
lour, and the digital joint, which is the darkest, has a small 
curved claw at its extremity. The abdomen is of an oblong- 
oviform figure, tapering a little to the spinners, which are pro-
