31. Neriene graminicolens. 



With the exception of the legs and palpi, which are of a uniform colour, 

 without any dark annuli, Neriene graminicolens so closely resembles Neriene 

 triUneata, as scareely to be distinguished from it ; but as this difference is con- 

 stant in all stages of the growth of these spiders, I am disposed to regard them 

 as specifically distinct. 



Neriene graminicolens occurs among long grass and coarse herbage growing 

 at the roots of trees in old pastures at Oakland, and the male lias the palpal 

 organs and the metatarsal joint of the anterior legs completely developed in 

 autumn. The contraction and expansion of the dorsal vessel are very appa- 

 rent in this species, but the number of pulsations in a minute varies with the 

 temperature of the atmosphere by which it is surrounded. 



Genus Manduculus, Blachv. 



32. Manduculus vernalis. 



Theridion vernale. Hahn, Die Arachn. b. ii. p. 38. tab. liii. fig. 123. 



In autumn, this spider, which belongs to the genus Manduculus, may be seen 

 running on the ground in pastures in various parts of Lancashire and Den- 

 bighshire, and specimens of it were comprised in the collection of spiders re- 

 ceived from C. C. Babington, Esq., in 1840. 



Genus Pholcus, Walck. 



33. Pholcus phalangioides.

My friend Richard Potter, Esq., M.A., of Queen's College, Cambridge, and 

 Professor of Natural Philosophy in University College, London, brought me 

 living specimens of Pholcus phalangioides from Barmouth in Merionethshire, 

 where he captured them in the summer of 1835. In 1836 I received an adult 

 male from T. Glover, Esq., which he had taken in Liverpool, and I have in 

 my possession an immature individual from the Isle of Wight.
