procoss, somewhat obscured by the tuft of hairs on the outside 

 of the radial joint. 



Examples of this spider, which I believe to be hitherto 

 undescribed, were contained in a collection made by Mr. H. C. 

 Young, of Glasgow, near that city, and kindly sent to me for 

 determination. 



NERIENE HUTHWAITII. 



Neriene huthwaitii, Cambr., Ann. and Mag. N.H., 3rd ser., 

 vol. vii., p. 436, and Blackw., I.e., p. 260, 

 pi. xviii., fig. 176. 



Length of the male 3-20ths of an inch. 



Nearly allied to Neriene affinis, Bl. (p. 114), but differs in the 

 shorter, and rather stronger, though similarly formed, palpi. 

 The falces are longer, but want the strong tooth in front. The 

 radial joint of the palpus is nearly or quite double the length 

 of the cubital, whereas these two joints in Neriene affinis 

 are oqual. The general colouring also in the present spider is 

 less bright. 



Found at Calke Abbey, near Derby ; also on Dartmoor, and 

 on tho Cheviot Hills, but exceedingly rare. 



NERIENE AGRESTIS. 



Neriene aqrestis, Blaokw., I.e., p. 276 (exclude references to 

 pi. xix., fig. 190, and pi. xxii., fig. D). 



The length of the adult male is 1-1 0th of an inch. 



Having very lately (July 6, 1 880) received from Mr. F. M. 

 Campbell, of Hoddesdon, an example of what I feel but little 

 doubt is the true Neriene agrestis, Blackw., I have come to the 

 conclusion that the spider described under that name (p_ 

 115) belongs to the very closely allied species Neriene fusca, 

 Blackw. These two spiders are so nearly allied that Mr. Black- 

 wall himself (who had long before lost the types of the two 

 species) some years ago repeatedly returned to me spiders of the 

 species described at p. 115 under the names of both fusca and
