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 Dbassid^.

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 maxillse 

 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 papillae, and the tibise 

 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- 

 loui', 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-
