124 Mr. Blackwall's Catalogue of Spiders 



A collection of spiders captured in various parts of England by C. C. Babing- 

 ton, Esq.. and obligingly transmitted by him to me in the year 1840, contained 

 an adult male of this species ; and T. Glover, Esq., has taken Sparassus sma- 

 ragdulus, in an immature state, in the woods at Tan y Bwlch in Merioneth- 

 shire. 



Family Theridiid^. 



Genus Theridion, IValck. 



28. Theridion denticulatum. 



Theridion denticulatum. Walck. Tabl. des Aran. p. 74. 



Crevices in rocks and walls, and the branches of trees growing against 

 buildings, are the usual haunts of this species, which is common in England 



and Wales. 



29. Theridion signatum. 



Theridion signatum. Walck. Tabl. des Aran. p. 76. 



Asagena serratipes. Koch, Die Arachn. b. vi. p. 98. tab. cciv. fig. 502, 503. 



M. Koch, without any apparent reason, has transferred Theridion signatum 

 from the family Theridiidce to that of Agelenidce. (Uebersicht des Arachn. 

 Syst. p. 13.) 



This remarkable species is found among heath in Denbighshire, but is of 

 rare occurrence. The fourth and fifth palpal joints of the male are so closely 

 connected, as scarcely to present any perceptible trace of their union ; indeed, 

 as they appear to be quite incapable of separate motion, there seems to be an 

 impropriety in regarding them as distinct joints. 



Genus Neriene, Blackw. 



30. Neriene trilineata. 



Theridion reticulatum. Hahn, Die Arachn. b. ii. p. 39. tab. liv. fig. 124. 

 Bolyphantes trilineatus. Koch, Die Arachn. b. viii. p. 67. tab. cclxxii. fig. 641. 



This spider, which belongs to the genus Neriene, is found under stones in 

 the neighbourhood of Manchester. Koch, perceiving that it and some nearly 

 allied species differed essentially from the true Theridia, has proposed the ge- 

 nus Bolyphantes for their reception.
