indigenous to the Salvages. igs 
the design formed by their distribution, and also in the relative 
length and proportions of its legs, that the description of one 
might well serve for that of the other, were it not for the re- 
markable difference in the structure of their spinners, Drassus 
Bewicku having the superior pair of those organs very long, 
cylindrical, and triarticulate, with the spinning-tubes distributed 
on the extremity of the short terminal joint ; the extraordinary 
length of the middle joint of these spinners constitutes an im- 
portant and conspicuous character, by which it may be readily 
distinguished, not only from Drassus Paivani, but also from 
every other known species of the genus. 
This and the preceding species belong to Walckenaer’s family 
Lithophile, of the genus Drassus. There were eight specimens 
of this spider in the collection, all of which were either adult or 
immature females. 
I have conferred on this remarkable species the name of Mr. 
Bewicke, a zealous and careful observer of nature, who, having 
collected numerous specimens of spiders in the island of Madeira, 
transmitted them to Mr. Wollaston, by whom they were kindly 
placed at my disposal. In describing the new species comprised 
in that collection in the ‘ Annals and Mag. of Nat. Hist.,’ third 
series, vol. ix. page 370, my omission to acknowledge the obliga- 
tion I was under to those gentlemen must be attributed to my 
not having received information of the-circumstance at that 
‘time. 
Family AGELENIDZ. 
Genus TeGenartiA, Walck. 
Tegenaria dubia. 
Length of an immature female (not including the spinners) 
7oths of an inch; length of the cephalothorax +; breadth ;,; 
breadth of the abdomen ;4,; length of an anterior leg 35; 
length of a leg of the third pair 2. 
The eyes are seated on black spots, and are disposed on the 
anterior part of the cephalothorax in two transverse rows ; the 
posterior row, which is rather the longer, is slightly curved, with 
its convexity directed backwards, and the anterior row is almost 
straight ; the four intermediate eyes describe a trapezoid whose 
shortest side is before, the two posterior ones being the largest 
and the two anterior ones the smallest of the eight; the eyes of 
each lateral pair are placed obliquely on a tubercle, but are not 
‘in contact. The cephalothorax is convex, glossy, compressed 
before, and rounded on the sides, which are depressed, and 
marked with furrows converging towards a narrow, oblong in- 
dentation in the medial line of the posterior region ; it has a 
brownish-yellow hue, with a broad, irregular, faint soot-coloured
