Linyphia triangularis occurs in the south-eastern counties of 

 England, but I have not met with it in the northern counties, 

 nor in Wales.

Titulus 19, Lister, Hist. Animal. Angl. De Aran. p. 64. tab. 1. fig. 19. 



In its habits and oeconomy this species resembles Linrjphia 

 montana, fabricating in low bushes or among coarse herbage 

 an extensive snare similar in design to the toils constriicted by 

 the Linyphice generally. It pairs in May, and in June the female 

 sjnns one or two lenticular cocoons of white silk of a loose texture 

 which are attached to withered leaves, or other objects situated 

 near the snare ; the larger of these cocoons measures ^ an inch 

 in diameter, and contains about 140 spherical eggs of a pale 

 yellow colour, not agglutinated together.

sylvatica, Blackw. Linn. Trans, vol. xviii. p. 659. 



Since the publication of my description of this spider, under 

 the specific name of sylvatica, in the eighteenth volume of the 

 'Transactions of the Linnsean Society,^ the suspicion of its identity 

 with the Linyphia pratensis of M. Wider, there expressed, has 

 been converted into absolute certainty by consulting M. Rcuss's 

 memoir entitled * Arachniden,' contained in the first volume of 

 the * Museum Senckenbergianum ; ' consequently the appellation 

 bestowed upon it by me must rank as a synonym. It will be 

 seen that this opinion has been adopted by M. Walckenaer, on 

 referring to his * Hist. Nat. des Insect. Apt.' t. iv. p. 499. 



This species is common in England and Wales, and in the 

 spring of 1849 an immature male, which had not undergone its 

 final change of integument, was forwarded to me by Mr. J. Hardy,
