58& PAPERS ON SPIDERS 



Oedothorax : 



All the species enumerated under this genus are included in Gongy- 

 lidiiim Cb., 1900, and Sim., A.F. Of Gongylidium the type is 

 rufipes Sund., and as the present species are not congeneric 

 with rufipes, Simon (Hist. Nat. des Araignees, 1894), following 

 Kulczynski (Aran. Hung.), adopted for this group Blackwall's 

 name Neriene. As originally propounded in 1833, Neriene con- 

 sisted of marginata Bl. (= Linyphia clathrata Sund.), rubens 

 Bl., and cornuta Bl., and no type was indicated. In 1868 

 Menge (Preuss. Spinn., vol. ii. ) made rubens Bl. the type of his 

 Gonatutm — a genus still maintained— under the name of Gonathcm 

 chelifencm Menge. Cornuta Bl. was thus left as the type of 

 Neriene, and the genus before us must take the name Oedothorax 

 (Bertkau, Beitr. z. Kennt. Spinn, f. Rheinp., 1883), the type 

 being gibbosa Bl.

The original types of Hilaira uncafa, H. pervicax, 

 Oreonetides abnormis, O. contritus, O. firtims $, Centromerus 

 prudens, C. arcanus, Sintula faiista ?, and Coryphceus dt's- 

 tlnctus ¥ were all Northumbrian ; while Oreojietides adipatus 

 was discovered in the Tyrol and on Cheviot Hill almost 

 simultaneously. Hilaira pervicax and Oreonetides contritiis 

 still remain peculiar to the county, and several others are 

 more abundant here than elsewhere, according to our present 

 knowledge — notably Diplocentria rivalis, Sintula fausta, and
