454 REV. O. P. CAMBRIDGE ON BRITISH SPIDERS. 
This species is, I believe, identical with the Erigone acuminata of Westring; but as 
the specific name acuminata had been long previously given to a very different spider 
of the same genus by Mr. Blackwall, the name under which it was described by myself 
shortly after its description in * Araneæ Suec.’ takes the precedence.

Erigone pusilla, Westr. Ar. Suec. p. 239. 
Walckenaéra minima, Cambr. Zoologist for 1863, p. 8595. 
This species is not rare among low plants and moss in woods at Bloxworth in spring 
and early summer. 
WALCKENAERA AFFINITATA. (Pl. XX XV. no. 30.) 
Walckenaéra affinitata, Cambr. Zoologist for 1863, p. 8591. 
The typical example of this species is the only one yet recorded. It was found in 
1860 by myself at Bloxworth, and is allied to W. humilis (BL.)., as well as to Erigone 
erassiceps, Westr. 
WALCKENAERA BREVIPES. (Pl. XXXV. no. 28.) 
Erigone brevipes, Westr. Ar. Suec. p. 294. 
Adults of both sexes of this spider, now first recorded as British, have been found 
among heath and moss at Bloxworth. It is very nearly allied to W. depressa (Bl.)— 
Erigone pheopus (Westr.), to which it bears close resemblance in general character and 
appearance, but may be distinguished by its smaller size (the adult male measuring only 
17 of an inch, or less than $ of a line, in length); the abdomen also projects more over 
the base of the cephalothorax ; and the height of the clypeus is considerably greater. In 
W. depressa it scarcely, if at all, exceeds the length of the space occupied by the four 
central eyes, while in the present species it exceeds it considerably; there seems also to 
be no impression at all in the clypeus, which, on the contrary, appears to be slightly 
prominent just below the eyes, while in W. depressa that part is slightly impressed. 
The palpi and palpal organs are similar in general respects; but the form of the upper 
extremity of the radial joint differs. In W. depressa it is broader and more prominently 
and obtusely produced than in the present species.

Mr. Blackwall has described (loc. cif.), under the name Epeira Mengii, a spider which 
I cannot help feeling convinced is only of the adult spring brood of Epeira inclinata (BL). 
It differs from this species in no respect that I can discover, either of structure, colour,
