266 F. M. CAMPBELL — SPIDERS OF HODDESDON. 



duccci one new species, viz. Amphissa spiyiigera, Cambr.,* whicli 

 (adult male) I noticed running quickly over my study-table in 

 January, 1880. It took refuge among some old bee-frames, and 

 as it is iV of an inch in length, I was fortunate in catching 

 it. I have not met with another specimen. 



The most abundant spiders in the marshy places in the Lea 

 valley are Cluhiona grisea, L. Koch, C. hohsericea, De Geer, 

 Neriene gihlosa, Blackw., N. tuberosa, Blackw., JV. bituhercnlata, 

 "Wid., Linyphia nigrina, "Westr., L. approximata, Cambr., L. pul- 

 lata, Cambr., Walckendera permixta, Cambr., Pirata p)iraticus, Clk., 

 and P. hjgrophilus, Thor. Neriene hituherculata may be said to 

 swarm there. 



The classification of the species in the following list is the same 

 as that adopted by the Rev. 0. P. Cambridge in ' The Spiders of 

 Dorset,' to which work the reader may turn for descriptive details. 

 The synonyms under which the species are described inBlackwell's 

 ' Spiders of Great Britain and Ireland ' are given, with references 

 to the drawings. 



I shall be much obliged to any members who will kindly send 

 me collections from different parts of the county. The mode of 

 capture and preservation is described on p. 141 of the present 

 volume of our * Transactions.'
