Spiders mid Arachnids from the Edinhnrgh District. 171 

 Diplocephalus speciosns (Cb.). 



Plcesiocrcerus speciosus, Cambr. Proc. Dorset Field Club, vol. xvi., 1895, p. 109. 



A single adult male of this minute and little-known 

 species was got among damp moss by the side of Bonaly 

 Burn, Peutland Hills, on 28th April 1898. The type 

 specimen — the only other one as yet recorded from Great 

 Britain — was taken at Bloxworth, Dorset ; in Ireland, how- 

 ever, where it seems to be widespread, it has occurred in 

 several counties (see Carpenter's " Spiders of Ireland," Proc. 

 Boy. Irish Acad., 3rd ser., vol. v., 1898). There is no doubt 

 that the genera Dij^locephalus and Plmsiocrcerits should be 

 united, and the former name being the older must be 

 adopted. 



Diplocephalus latifrons (Cb.). 



Walckenaera latifrons, Cambr. Spid. Dorset. 



A pair (ad. 6 and ?) of this form, which, though scarce, 

 seems to have a wide range in Europe (West of Ireland 

 to Northumberland and Dorset; Denmark and France to 

 Hungary), were found under a piece of wood lying on dead 

 leaves at Mortonhall, near Edinburgh, April 1898. The 

 only other Scottish record is from Eenfrewshire (Morris 

 Young, Annals Scot. Nat. Hist, 1894, p. 185). 



Diplocephalus beckii (Cb.). 



Walckenaera hecMi, Cambr. Spid. Dorset. 

 Plcesiocrcerus heckii, Simon, Aracbn. France. 



The Eev. 0. P. Cambridge has detected, among a number 

 of small spiders which w^e recently sent to him from the 

 neighbourhood of Edinburgh, an adult male of this rare 

 species. It was got in October 1896 — we believe among 

 moss, on Corstorphine Hill. Its recorded occurrences in 

 Britain are very few — Dorset, near London, and near 

 Dunkeld (Prof. Trail).
