444 REV. O. P. CAMBRIDGE ON BRITISH SPIDERS. 
easily be distinguished both from 7. atrica and others by the large size of the digital 
joints of the palpi, and the palpal organs of the male; the spinners are banded with 
black. | 
I have found this species (though not very commonly) both in Hampshire and Dorset- 
shire, under the shelter of banks overgrown with heath and fern, or choked with weeds 
and dead rubbish, and also among brickbats thrown together in a heap and untouched 
for several years. | 
Genus CaLorEs (Bl.). 
CŒLOTES MŒRENS. 
Cœlotes marens, Cambr. Zoologist for 1863, p. 8572. 
No other example of this spider has been found since the capture of that which has 
been described in the Zoologist (loc. cit.). I still believe it to be a good species, although 
the only known example was in an immature state. 
CŒLOTES ? IMMACULATUS, n. Sp. 
Female adult, length 3 lines. 
This spider has the cephalothoraz, falces, palpi, and sternum of a clear and rather 
brightish and glossy yellow, without markings of any kind; the legs are also of a similar 
colour, except the tibiæ, tarsi, and metatarsi, which are tinged with reddish. 
The labium and maxille are rather suffused with yellow-brown. 
The abdomen, which is of an oval form, is of a pale luteous or anis ies colna, 
and furnished with a very few short, fine, scattered hairs. 
The spinners are short; the four outer ones describe a transverse parallelogram, and 
are of equal length. 
The /egs are moderately long and strong, their relative length appearing to be 4, 1, 2,3. 
The tarsi and metatarsi are armed beneath with two longitudinal parallel rows of long 
strongish spines; each tarsus terminates with ¿hree curved black claws; the two supe- 
perior ones on the tarsi of the fourth pair of legs are longer than the rest. 
The eyes of the foremost row are equidistant from each other; the difference in size 
between all the eight eyes appears to be slight;. when looked at from the front, both 
rows have their curves directed backwards, that of the hinder row being the strongest, 
while the front row is the shortest of the two; the two central eyes of the hinder row are 
further from each other than each is from the lateral on its side. 
The clypeus is about equal in height to the length of the line described by the fore 
central pair of eyes; the lateral pairs are seated obliquely on tubercles, and the eyes 
of each are near together, but not contiguous. The falces are long, strong, and pro- 
tuberant near their bases in front. 
The maxille are oblong, strong, and about double the length of the labium; they are 
slightly curved; but their direction is straight, and they have no inward curvature; their 
extremities are rounded on the outer, and rather obliquely truncated on the inner side. 
A single example of this fine and distinct species was contained in a large collection of 
spiders received from Mr. William Farren, of Cambridge, by whom it was captured in 
Wicken Fen, and kindly forwarded to me in 1869,
