Neriene trilineata is not uncommon in the neighbourhood 

 of Manchester, where it conceals itself under stones j and Mr. 

 R. H. Meade has met with it in Yorkshire. 



I am doubtful whether the spider named by me Neriene gra- 

 minicolens (Transactions of the Linnsean Society, vol. xix. p. 125) 

 is not a variety of this species, from which it differs chiefly in 

 not having dark annuli on the legs and palpi. 



The contraction and expansion of the dorsal vessel are very 

 apparent in Neriene graminicolenSy which occurs among grass 

 and coarse herbage in pastures at Oakland, and is probably 

 identical with the Linyphia cellulana of Prof. Sundevall (Vet. 

 Acad. Handl. 1831, p. 108).

 This species, which bears a strong resemblance to Neriene ru^ 

 bens, is found under stones and on plants growing in woods at 

 Oakland. The male has the palpal organs fully developed in 

 October.

In December 1837 I obtained males and females of this spider 

 under stones on Gallt y Rhyg, a mountain in the vicinity of 

 Llanrwst; and in 1841 Miss Ellen Clayton favoured me with 

 specimens taken at Ingleton in Yorkshire.

My son, John Blackwall, discovered an adult male of this 

 species, which is nearly allied to the spiders constituting the 

 genus Walckena'era,_ on the steps at Oakland in June 1841,
