The genital aperture is furnished with a strong, somewhat 

 tumid, but simply formed, epigyne (represented by fig. 5, d } 

 Plate VIII.) ; the abdomen is thinly clothed with hair, and pro- 

 jects pretty strongly over the base of the cephalothorax. 



A single example of this interesting spider was received from 

 Mr. Douglas, by whom it was found in the spring of 1875 near 

 Castle Douglas, Kirkcudbrightshire, Scotland. It differs from 

 nearly all other known British species of this genus in having 

 a series of large, well-defined, pale markings on the upperside 

 of the abdomen, and a broad, central, longitudinal band on a 

 pale yellowish ground on the underside. 



I feel great pleasure in connecting this spider with the name 

 of its discoverer, who appears to be entering upon the study 

 of Scottish spiders with considerable care and zeal. 



JErigone (Neriene) nigriceps, sp. n. PI. VIII. fig. 6. 



Adult female, length 1-|- line. 



The cephalothorax of this spider is of ordinary form ; the 

 hinder slope rather long and gradual ; the upper marginal 

 line, seen in profile, level, there being only the slightest pos- 

 sible depression near the occiput ; its colour is orange-yellow, 

 the caput being strongly suffused with black 5 and there are a 

 few fine bristly hairs along its central line, and within the 

 ocular area ; the normal furrows and indentations are visible, 

 but not strongly marked ; and the height of the clypeus (which 

 is a little prominent) equals half that of the facial space. 



The eyes are in the usual position on black tuberculate 

 spots, the foremost row (looked at from the front) being- 

 much the shortest and straight. Those of the hind central 

 pair are distinctly nearer to each other than each is to the 

 hind lateral eye on its side, being separated from each other 

 by less than an eye's diameter, and from the hind laterals by 

 at least a diameter, if not a little more ; those of each lateral 

 pair are placed obliquely and are contiguous to each other ; 

 the fore laterals are largest of the eight, and each is separated 

 from the fore central eye on its side by a very slight, though 

 distinct, interval, those of the fore central pair being almost, 

 but not quite, contiguous to each other. 



The legs are moderately long, rather strong, particularly 

 the femoral joints, their relative length being apparently 4, 1, 

 2, 3 ; they are of an orange-yellow colour, but not so dark as 

 the cephalothorax : the metatarsi and tarsi are rather paler than 

 the rest ; their armature consists of hairs and a few slender 

 prominent spine-like bristles on the femoral and tibial joints. 



The palpi are similar in colour and armature to the legs.
