446 REV. O. P. CAMBRIDGE ON BRITISH SPIDERS. 
peculiar position of the eyes of this species, a position so characteristic that Dr. Thorell 
has based a genus upon it. It is remarkable, too, that Mr. Westring should not have 
perceived that it was undeniably a Theridion rather than an Erigone. 
I have lately received this spider from the island of Sark, kindly sent for my examina- 
tion by Mrs. Collings, a diligent student of spiders. 
Genus LINYPHIA (BL). 
LINYPHIA CRUCIGERA. : 
Linyphia crucigera, Bl. Ann. & Mag. Nat. Hist. for Oct. 1863. 
In 1869 I received from Mr. W. Farren, of Cambridge, several very young examples 
of this well-marked species, taken in Wicken Fen, the same locality as that from which 
the typical example was obtained. The dusky margin of the cephalothorax, and the 
dark cruciform marking on the white ground-colour of the abdomen are very charac- 
teristic. 
LINYPHIA SETOSA. (Pl. XXXIII. no. 10.) 
Linyphia setosa, Cambr. Zoologist, 1863, p. 8578. 
The ocular region of this spider is very prominent, and beset with numerous strong 
bristles directed forwards; this character distinguishes it from the majority of the British 
Linyphie ; the palpal organs are exceedingly complex and peculiar in form. The typical 
pair, captured at Bloxworth in 1862, are as yet the only recorded examples of the species. 
LINYPHIA PULLATA. (Pl. XXXIV. fig. 12.) 
Linyphia pullata, Cambr. Zoologist, 1863, p. 8580. 
This spider may be distinguished from its near ally, Z. pulla (BL), by the smaller size 
of the digital joint of the male palpus, and also by the structure of the palpal organs, 
which have no circularly curved filiform spine at their extremity. I have not met with 
L. pullata anywhere except at Bloxworth. 
LINYPHIA ? OBLIVIA, n. sp. (Pl. XXXIV. fig. 13.) 
Male adult, length ¿ of a line. 
‘This species is very similar in size and colour to Neriene gracilis (BL) and Neriene 
flavipes (Bl.) (between which two species I can find no distinction); it may, however be 
distinguished by the comparative feebleness of the falces, and by the absence of a small 
pointed projection at the extremity, on the outer side, of the radial joint of the male 
palpus. The legs also have a few long, distinct, erect spines, which are merely replaced 
by strong but shorter bristles in NV. gracilis. 
The cephalothoraz is of a dull brownish yellow, margined with black-brown, and with 
a considerable patch of the same colour, of a semiquadrate form, at the junction of the 
. eaput and thorax; some dark brown converging lines following the normal grooves and 
indentations, meet in a small indentation at this junction. When looked at in profile, 
the thoracic portion is distinctly higher than the caput; the ocular region is slightly ©
