dicular, and furnished with teeth on the inner surface. Maxilla? 

 enlarged at the apices, and slightly inclined towards the lip. 

 Pectus heart-shaped. In structure and relative length the 

 legs and palpi are similar to those of Neriene marginata. The 

 colour of these parts is red-brown, the pectus, lip, maxilla?, 

 and margins of the cephalothorax being the darkest ; and the 

 eyes are placed on black spots. Abdomen oval, convex above, 

 projecting over the base of the cephalothorax, thinly clad with 

 hair, glossy,and of a brownish-black colour.

The male, though rather smaller than the female, resembles 

 it in colour and in the relative length of its legs : but the an- 

 terior part of the cephalothorax is supplied with slender bris- 

 tles curved forwards.. The third and fourth joints of the palpi 

 are short ; the former is terminated by a fine bristle in front, 

 and the latter, which is the stronger, has a small protuberance 

 on the outer side of the upper part, fringed with long bristles ; 

 the fifth joint has a large, obtuse apophysis near its articula- 

 tion with the fourth ; it is of an oval form, convex externally, 

 concave within, comprising the sexual organs, which are highly 

 developed, complicated in structure, and of a dark red-brown 

 colour. 



This species abounds in the plantations about Crumpsall 

 Hall, constructing in the long grass under the trees a web 

 similar to that of Neriene marginata. It is of frequent occur- 

 rence also under stones. 



Neriene rujvpes. 



This species has the cephalothorax of an oval form ; it is 

 convex above, and glossy, with the anterior part about the 

 region of the eyes rounded and somewhat depressed, and in 

 the medial line of the posterior part a small indentation oc- 

 curs. Mandibles powerful, conical, provided with teeth on 

 the inner surface, and inclined a little towards the pectus, 

 which is heart-shaped. Maxilla? enlarged at the apices, and 

 inclined towards the lip. The legs and palpi are similar in 

 structure and relative length to those of Neriene bicolor. These 

 parts are of a light red-brown colour, the mandibles, pectus, 

 lip, and maxillae, being the darkest, and the eyes are placed 

 on black spots. Abdomen oval, slightly convex above, pro- 

 jecting over the base of the cephalothorax ; it is rather hairy, 

 glossy, and brownish-black. Plates of the spiracles large, 

 and of a yellowish-white colour.
