different from Sparassus smaragdulus, it will be easy to distinguish it at first sight by its 
red-striped cephalothorax, and abdomen speckled with the same colour. The example 
recorded by Mr. Blackwall was immature, and, except by the red stripes and spots, not 
distinguishable from S. smaragdulus. 1 have myself found at Drayton Beauchamp, 
Bucks, several young examples only thus distinguishable, among numerous individuals 
of the same age, of smaragdulus, captured at the same time and on the same spot. I 
am inclined to think it is but a variety of that species. 
Family DRASSIDES. 
Genus Drassus (Bl.). 
DRASSUS PEDESTRIS. : 
Melanophora pedestris, Koch, Die Arachn. Bd. vi. p. 82, pl. 200. fig. 489. 
Drassus pedestris, Bl. Ann. & Mag. Nat. Hist. for December 1861; Cambr. Zoologist for 1861, 
p. 7558. 
In addition to the localities given by Mr. Blackwall and myself in the above notices, I 
have received this species from Mr. Parfitt, of Exeter. It is not difficult to distinguish ` 
D. pedestris from other British Drassi, by its smoother and more shining abdomen, which 
(with the cephalothorax) is mostly jet black, and by the tarsi and metatarsi, which are 
of a bright reddish yellow-brown. Its habitat is under stones and pieces of broken rock. 
DnRassus? SUBNIGER. (Pl. XXXIII. no. 3.) 
Drassus subniger, Camb. Ann. & Mag. Nat. Hist. 
This puzzling little spider has been conjectured to be of the genus Apostenus (Westr. 
Ar. Suec. p. 322); it is, however, certainly distinct from the typical species (of which I 
have received an example from Dr. Thorell, of Upsala, Sweden), and, I think, also of a 
totally different genus. 
DRASSUS PUBESCENS. 
Drassus pubescens, Thor. Recensio Crit. Ar. Suec. p. 110; L. Koch, Die Arach. Fam. der Drassiden, 
p. 123, tab. v. fig. 77-79. 
An adult male of this spider, hitherto unrecorded as British, was found by myself 
under a stone on Bloxworth Heath. It is nearly allied to D. lapidicolens, which it much 
. resembles in general appearance, but is very readily distinguished by its smaller size and 
shorter falces and palpi, which last are also proportionally stronger. The radial joint has 
a short pointed projection at its extremity on the outer side; this projection differs from 
that on the radial joint of the palpus of D. lapidicolens in being stronger, and bifid at its 
extreme point; the two hind central eyes are also larger and nearer together than in 
that species; the falees also want the strong tooth near their inner extremities; and the 
palpal organs are visibly different in their structure. 
Genus LrocRANUM (L. Koch). 
LiocRANUM PRÆLONGIPES. (Pl. XXXIII. no. 4.) 
Drassus prelongipes, Cambr. Ann. & Mag. Nat. Hist. June 1861. 
This little spider evidently belongs to Dr. Ludwig Koch's genus Liocranum, having
