new Species of Araneidea. 347 



somewhat roundly truncated at the apex, and of a dark black- 

 brown hue. 



The sternum is similar to the labium in colour. 



The abdomen is narrow oviform, glossy and black, and 

 thinly clothed with hairs. 



A single example of this spider, which is allied to Neriene 

 subtilis, N. conigera, and N. innotabilis, Cambr., was received 

 from Count Keyserling, by whom it was found in Liivland. 



Gen. Walckenaera, Bl. 

 Walckenaera nasuta, sp. n. (PI. XVII. fig. 4.) 



Adult male, length y 1 ^ of an inch. 



The cephalothorax, legs, palpi, and falces are of a light 

 rather orange-yellow colour, the tibia?, tarsi, and metatarsi 

 of the legs being a little the palest, and the caput slightly suf- 

 fused towards the fore part on the upperside with a dusky 

 brownish hue. The caput is elevated, and the fore extremity 

 of the upperside projects forwards in a somewhat curved 

 and tapering form, terminating in a round knob connected 

 with the main portion by a narrow neck-like constriction, and 

 giving it a very nose-like appearance ; the fore part of the 

 caput, as well as the knob, is furnished pretty thickly with 

 hairs ; there are also a few shorter ones along the upperside of 

 the caput, directed slightly backwards. The thorax is a little 

 gibbous about the middle of the upperside. 



The eyes are small, seated on black spots, and in the usual 

 four pairs ; the lateral pairs are one on each side, towards the 

 fore extremity of the caput, at about the thoracic level ; the 

 fore-central pair is in front, between and on a level with the 

 laterals ; the eyes of these three pairs are respectively con- 

 tiguous to each other, while those of the hind-central pair are 

 wide apart, one on each side of the produced part of caput, a 

 little behind the neck or constriction. 



The legs are slender, not very long, furnished with ordinary 

 hairs, and a few erect ones on the upperside of the tibise and 

 metatarsi. 



The jpaZpi are moderately long ; the cubital joint is rather 

 long and slightly clavate ; the radial joint is short, but has 

 its fore extremity produced into a long, tapering, twisted, 

 sharp-pointed, rather prominent apophysis. The length of 

 this joint and its apophysis is about equal to that of the 

 cubital joint. The digital joint is of moderate size ; and the 

 palpal organs are prominent and rather complex, but have no 

 very remarkable processes. 



The abdomen is oviform ; it projects but slightly over the
