18/2.] NEW SPECIES OF ERIGONE. 757 



The legs are long and slender ; their relative length 4, 1,2, 3, 

 those of the fourth pair being perceptibly the longest ; they are 

 furnished sparingly with hairs ; each genual joint has a short black 

 bristle on its fore side ; and another similar one is placed about the 

 middle of the uppersides of the tibise. 



The palpi have the cubital joints clavate, short, and bent down- 

 wards ; the radial is of about equal length with the cubital, and is pro- 

 duced at its extremity into two short points, one on the inner, the 

 other on the outer side, forming a strongly emarginate margin : the 

 digital joint is large and of an irregular and unusual form ; it has a 

 large, sharp-pointed, nearly concave prominence towards the ex- 

 tremity on the outer side, and another at its base on the same side, 

 whose extremity is almost in contact with the fore extremity of the 

 radial joint ; these prominences run together ; and the upper line of 

 communication is black and fringed with short strong bristly hairs : 

 the palpal organs are very prominent, well developed and complex ; a 

 fine black spine issues from near their fore extremity, and curves 

 backwards and inwards with a large, prominent, circular sweep. The 

 sternum is similar in colour to the abdomen. The falces are rather 

 long, moderately strong, straight (?), vertical, and with a few very 

 minute teeth near their extremity on the inner side. 



Examples of both sexes of this Spider were received in 1866 from 

 M. Eugene Simon, by whom they were captured near Paris ; and a 

 single adult male was subsequently sent me for examination by Dr. 

 L. Koch, by whom it was found at Nuremberg. 



The female resembles the male in colours ; but the abdomen is far 

 more convex above, and the genital aperture is of a bright deep red- 

 brown colour. 



Erigone (Neriene) sarcinata, sp. n. (Plate LXV. fig. 13.) 



Male adult, length I line. 



This Spider is nearly allied to Neriene excisa (Camhr.) : like that 

 species, there is a protuberance or gibbosity on the back part of the 

 caput ; but in the present species this gibbosity is situated nearer to 

 the thoracic junction, and is divided from the fore part of the caput 

 by a distinct and rather deep oblique cleft. It is also, when looked 

 at from above and behind, pointed at its fore extremity ; the portion 

 of the caput between the cleft and the hind central eyes is also rather 

 gibbous, that part and the outer area forming a longish uniform 

 slope to the clypeus, which is less in height than half that of the 

 facial space. The colour of the cephalothorax is yellow-brown, the 

 gibbosity of the caput being paler. The falces are neither very long 

 nor strong, and are similar in colour to the cephalothorax, The legs 

 are long, relative length 4, 1, 2, 3, moderately strong, yellow in 

 colour, and furnished with hairs; there is a single short, slender 

 black bristle at the fore extremity, on the upperside, of the genual 

 joints, and a few long, diaphanous, pale, slender erect bristles on 

 other parts of the legs. 



The palpi are moderately long and strong ; the cubital is upwards 

 of three times the length of the radial joint, which is slightly pro-
