ON NEW AND RARE BRITISH SPIDERS. 1 63 



convexity directed forwards ; the eyes also of the fore-central 

 pair form a shorter line in comparison with the hind-centrals 

 than in that species ; the ocular area is also smaller, and the 

 eyes themselves rather smaller. The legs are longer, as are also 

 the palpi, the structure of the palpal organs being also different. 

 The form of the cephalothorax also is less circular, being longer 

 than broad, that oiinoruata is circular or almost so. Looked at 

 in profile the clypeus is more vertical and less impressed in the 

 present species, and the profile from the eyes to the hinder part 

 is more convex, forming a stronger curve. 



The female also may be distinguished not only by some of 

 the foregoing characters, but also by a difference in the form of 

 the genital aperture.

Leptyphantes acceptus, sp.n. Fig. 4. 



Adult male, length i line. Adult female slightly less. 



This spider is very nearly allied to Leptyphantes Mengii, Kulcz. 

 It is, however, a little larger than most of the examples I have 

 yet seen of that species, and the abdomen has no lateral white or 

 pale spots or irregular broken stripe, such as is visible in all I 

 have come across of Z. Meugii. Its abdomen is of an uniform 

 pale yellow-brown hue on the upper side, with some transverse 

 darker indistinct angular lines or chevrons on the hinder part, 

 very much, in fact, like many examples of Bathyphantes gracilis, 

 Bl. ; the sides and under side are of an uniform darker yellow- 

 brown. The cephalothorax appears to be, when looked at in 

 profile, of a more uniformly curved or convex outline than that of 

 L. IMengii. Its colour is of a dull orange-yellow, the legs being 

 of a clear rather paler yellow, and the spines are very long. The 

 palpi and palpal organs are very like those of Z. Meugii, but 

 there are slight differences in the form of a very distinctive 

 portion of these organs — the paracymhimn, or large crescent- 

 shaped process at their upper part on the outer side. The 

 single female I have seen resembled the male in colours and
