440 REV. O. P. CAMBRIDGE ON NEW BRITISH SPIDERS. 
NERIENE EXCISA, n. sp. (Pl. 56. no. 29.) 
Length +; of an inch. 
Cephalothorax broad, oval; caput gibbous behind the eyes, leaving the eyes on a sort 
of shelf or platform in front of the gibbosity, which forms a low broad eminence some- 
what pointed forwards, and nearly flat at the top; this eminence melts away, without 
any strong line of demarcation, into the sides and hinder part of the caput, and so 
into the thorax. "The normal grooves on the sides and hinder part of the cephalothorax 
are visible, but not very strongly marked. The clypeus is about equal in height to the 
distance from the middle anterior to the posterior eyes, including the diameter of the 
eyes themselves; it is perpendicular, but slightly impressed just above the falces; a few 
short hairs at the fore part of the eminence are directed forwards; colour dark brown, 
shining, but, seen in a strong light and with a lens, minutely punctuose. 
Eyes eight, in two nearly straight rows, the front row very slightly curved forwards; 
they are nearly equal in size; the fore ones of the side pairs are, if any thing, slightly 
the largest; the centre ones of the hinder row are rather nearer together than each is to 
the end one on its side; those of the front pair are nearly contiguous, and distant from 
the hind pair about a diameter; those of the lateral pairs are close together on a black 
 tubercle, and placed obliquely. ; 
Legs moderately long and strong, of a pale yellowish colour, sparingly furnished with 
fine sessile hairs, among which are a very few stronger and more erect ones. 
Palpi similar in colour to the legs, moderate in length and strength ; humeral joint 
curved towards the falces; cubital slightly larger at the extremity than at the base; 
radial joint shorter than the cubital, and considerably broader at the extremity than at 
the base, and with two projections from its extremity ; one beneath it is short and bluntish- 
pointed, and the other, on the upperside, is long, prominent, ending in a sharpish point, 
to which it tapers gradually; its extremity is slightly curved outwards and upwards; 
this latter projection is pale-coloured and semidiaphanous; the extremity of the radial 
joint has some longish fine bristly hairs, some of which form a row towards the outer 
side of the fore margin; the digital joint is hairy; the palpal bulb is not very large, 
the palpal organs are moderately prominent and complicated, with two or more black 
spines at their extremity, one of which (stronger than the rest, and curved) projects con- 
spieuously. 
Falces long, not very powerful, slightly divergent, armed with long, strongish, sharp 
teeth on the inner margin, and there are some bristly hairs towards the extremity on 
the front and sides ; the colour of the falces is the same as that of the cephalothorax. 
Maxille long, strong, nearly touching over the labium ; in colour like the legs. 
Labium shortish, semicircular. 
Sternum very broad, strong, and heart-shaped, similar to the cephalothorax in colour. 
Abdomen short, broad, oval, hairy, and of a sooty black colour. 
An adult male of this very distinet species was forwarded to me, among others, in 1866, 
by Mr. Morris Young, of Paisley, by whom it was captured near that town. It may 
easily be distinguished from all others allied to it by occipital eminences (such as N | 
apicata (BL), N. elevata (Camb.), N. gibbosa (BL), N. tuberosa (BL), and others described m
