central eyes, and the hind-lateral eye next to it, is a shallow 

 impression, which, being partly edged with black, is very 

 perceptible from above. The height of the clypeus is less than 

 half that of the facial space. 



The legs are moderately long (4.1.2.3.), slender, furnished with 

 hairs and a few erect bristles, ono issuing from near the middle 

 of each of the tibiae of the fourth pair being longer than the rest, 

 and of a spinous nature. The falces are moderately long, toler- 

 ably strong, straight, and a Uttle inclined to the maxillae, which 

 (with the labium) present no noticeable feature. 



The abdomen is of a short-oval form, with a considerable 

 upper convexity. It is thinly clothed with coarsish hairs, and 

 projects a Uttle over the base of the cephalo-thorax. 



The genital aperture is small and margined with brightish 

 red-brown. From its anterior margin a long, slender, nearly 

 cylindrical, slightly bent, diaphanous process (or epigyne), 

 extends backwards in close proximity to the inferior surface of 

 the abdomen. The point of this process reaches half way 

 between the fore extremity of the abdomen and the spinners, 

 which last are very short and of a pale dull yellowish hue. 



A single example of this very characteristic little spider, which 

 is allied to Neriene diluta, Camb-, was found among heather on 

 Bloxworth Heath, in October, 1878. 



The long slender genital process distinguishes it readily from 

 all others of this group yet known to me.

The cephalo-thorax is of ordinary form. The marginal con- 

 striction on each side of the caput is slight, the occiput a little 

 rounded, and with only a slight depression between it and the 

 thoracic indentation. The oblique grooves marking the junction 

 of the caput and thorax are strong, and, together with those on
