IV. On British Spiders. By the Rev. O. P. CAMBRIDGE. Supplement to a communica- 
tion “on British Spiders new to science," $c., read before the Linnean Society, 
January 20th, 1870. 
-(Plates XXXIII.-X XXV.) 
Read June 15th, 1871. 
IN a paper on British Spiders, published in the Transactions of the Linnean Society, 
vol. xxvii. p. 393, 1871, a number of new and rare species (for the most part discovered 
after the publieation of Mr. Blaekwalls work on British and Irish Spiders) were 
recorded. Since the MS. of that paper left my hands, some other new and interesting 
species have come under my notice; these 1 propose now to record and describe, in- 
cluding with them notices of various other spiders, of which Mr. Blackwall's work con- 
 tains no mention, as they have also been discovered since its publication, though recorded 
and described in the ‘Zoologist’? and ‘Annals and Magazine of Natural History. ` 
The present and former papers therefore contain a summary of the discoveries in British 
araneology from the time of Mr. Blackwall's work being published down to the pre- 
sent date, January 1871; and together they form a kind of supplement (necessarily, 
however, imperfect) to that work: the imperfection consists chiefly in the comparative 
seantiness of the illustrations, and the omission of detailed descriptions of all except 
those spiders which have never, it is believed, been described until recorded in these two 
papers. 
Family Lx cosrDEs. 
Genus HEcAËRGE (BL). 
HECAÉRGE NEMORALIS. (Pl. XXXIII. no. 1.) 
Hecaérge nemoralis, Bl. Ann. & Mag. Nat. Hist. ; Cambr. Zoologist for 1863, p. 8597. 
Closely allied to Hecaérge spinimana, Bl. Brit. & ir. Spid. p. 41, pl. iii. fig. 21, this 
species may easily be distinguished by being rather densely covered with a longish, 
silky, grey pubescence. It was first taken by Mr. Blackwall in North Wales, and since 
by myself at Bloxworth, Dorsetshire, in the same localities as its ally, H. spinimana. 
Family SALTICIDES. 
) Genus SazTious (Bl.). 
SALTICUS SANGUINOLENTUS. 
Attus sanguinolentus, Walck. Ins. Apt. tom. i. p. 473. 
Salticus sanguinolentus, Hahn, Die Arachn. i. p. 51, pl. 14. fig. 39. 
This strikingly handsome spider is included in the British list on the authority of the 
late Dr. Leach (Edinb. Cyclop. vol. vii. p. 428). No locality is given by that author, 
who merely states it to have occurred “once only in Britain;” it is not rare in many
