directed forwards), but of different widths. Sides, part just 

 above the spinners, and under side black-brown, the latter part 

 the darkest coloured. 



An adult female differed from the male in having the cephalothorax 

 dark brown, and in the patch and bars on the abdomen being of greater 

 extent and all run together, leaving an interrupted band of yellow on 

 either side, and two or three obscure spots of the same colour below 

 each band on the lower margin of the abdomen. The specimens above 

 described were captured by myself on Blox worth Heath, in May, 

 1862. It is a striking-looking species, and the horn-like projection at 

 the base of the digital joint, together with the two curved spines enve- 

 loped in membrane connected with the extremity of the palpal organs, 

 will serve to distinguish it at once from others of the genus Linyphia. 



LlNYPHIA PULLATA. 



Male, adult. Length 1-tenth of an inch. Length of cephalothorax 



1 -twenty-first. Relative length of legs, 1, 4, 2, 3. 

 Cephalothorax rather shorter than the abdomen. A strong oblique 

 indentation on the sides just behind the ocular region, and a 

 broad shallow one towards the hinder part. Colour brownish 

 yellow, suffused on the sides and margin^ with sooty black ; 

 some specimens have but little of this suffusion ; others are 

 entirely of a sooty black on the cephalothorax. 

 Eyes in two rows, on front of cephalothorax. The front row is the 

 shortest and nearly straight, and the hinder row is curved away 

 from it. They are nearly equal in size ; the two centre ones of 

 the hinder row slightly the largest, and those of the front row 

 slightly the smallest of the eight : these last are close together, 

 but do not touch each other. The eyes of the hinder row are 

 about equidistant from each other. 

 Legs long and rather slender. The first, fourth and second pairs 

 do not differ much in length. They are of a yellow colour, 

 thinly clothed with hairs and a few longish fine spines on the 

 upper sides of the femoral and tibial joints. 

 Palpi short, like the legs in colour. Radial joint larger and stronger 

 than the cubital : these joints are furnished with several longish, 

 curved, black, bristly hairs, directed forwards. Digital joint 

 large and slightly protuberant on the outer side ; it is darker in 

 colour than the rest of the palpus, and hairy. Palpal organs 

 well-developed and prominent, but not very complicated. One
