552 REV. O. P. CAMBRIDGE ON NEW AND RARE BRITISH SPIDERS. 
over the base of the cephalothorax; it has but a few very short hairs on its surface, 
which is glossy and punctured all over with minute impressed dots. 
A single example of this very distinct species was contained in a collection received 
from Mr. J. W. H. Traill, by whom it was found near Aberdeen, and kindly forwarded 
to me. The crooked form of the apophysis at the extremity of the radial joint of the 
palpus is very different from any thing that has hitherto come under my notice, and, 
with the long filiform spine connected with the palpal organs, will serve to distinguish it 
from. its congeners at a glance.

Adults of both sexes were found in Mr. Hardy's Northumberland collection ; and 
while collecting insects and spiders in the woods of Sir Harry Verney, near Oxford, at 
the beginning of June 1872, I found a female of Dolomedes mirabilis carrying off in her 
falees an adult male of S. prominens, tightly enveloped in a thick silken tissue, but 
still alive.

A comparison of well-authenticated examples of all the spiders included in the above 
synonyms has proved their identity with each other. Numerous examples of this species 
. were found by myself among low herbage at Wick Copse, near Oxford, in June 1872. 
Some of the females (including examples of the var. anthracina and transitional forms 
between it and the typical form of S. trifasciata) were adult; but the males were all 
immature. 
EPEIRA (SINGA) SANGUINEA.

Epeira herii, Blackw. Spid. Gt. Brit. & Ir. p. 366, pl. xxvii. fig. 264. 
An adult male, with females both adult and immature, were received in June 1872 
from the Rev. C. W. Penny, by whom they were captured near Wokingham, and kindly 
forwarded to me. These adult examples, identical with adult and immature females and 
immature males of Epeira herii (Blackw.), prove their distinctness from Singa trifasciata 
(Koch) ; the adult male above mentioned is also identical with an adult German example 
of the same sex received from Dr. Thorell under the name Singa sanguinea (Koch), which 
is evidently a distinct species from Singa heri? (Koch).
