allied species which exhibit the same process on the male 

 palpal organs highly developed, though of a different form. 



Four males and one female of this curious little species 

 (which is new to the British list) were taken by myself on 

 Sept. 18, 1890, beneath stones upon the steep sides of the ridge 

 known as the Swirrel edge, close to the summit of Helvellyn. 

 They were apparently plentiful, and forty or fifty could no 

 doubt easily have been secured had I glanced at my captures 

 and perceived their value. 



Doubtless careful search will bring to light in these districts 

 some more of the continental species peculiar to the mountain 

 regions. 



Genus Tmeticus, Menge, Simon. 



This genus comprises a number of spiders very distinct in 

 general appearance from those of the last genus, or indeed 

 from those of the greater part of the Linyphini. 



They may be recognized by their rather short stout form, 

 by the round, somewhat hirsute abdomen, by their stout legs 

 and the bluffly rounded caput with eyes large and closely 

 grouped. 



They approach in general appearance the spiders comprised 

 under M. Simon's group Enoplognathini, but the margin of 

 the labium of these latter is not reflexed as it is in the Liny- 

 phini. 



The following species are found in Great Britain : — T. 

 hicolor^ Bl. (sub Linyphia^ Blk.^ and Neriene, Cambr.), 

 T. concinnus, Thor., T. sylvaticus^ Bl. {?>\xh Neriene) ^ T. rufus, 

 Wid., T. affinis, Bl. (sub Neriene)^ T. Huthwaitii, Cambr. 

 (sub Neriene), T. scopiger, Grube (^Linyphia rufa, Cambr.), 

 T. Warburtomi, Cambr., T. arcanus, Cambr. (sub Neriene, 

 Cambr.) , T. prudens, Cambr. (sub Neriene, Cambr.), T. ab- 

 normis, Bl. (sub Linyphia, BL), T. niger, F. Cambr. 



Of these T. hicolor, Bl., is by far the commonest, while 

 the others are all more or less rare, found beneath stones or 

 low down amongst herbage in damp situations. The species 

 described below appears to be quite new and forms a fine 

 addition to our spider-fauna. 



Tmeticus niger, sp. n. (PI. II. fig. IV. 1, 2, 3, 4, 5, 6.) 



Length of male 1^ line, of female 2 lines. 



Cephalothorax pale sepia-brown, depth of tint varying in 

 different specimens, the thoracic and cephalic lines of segmen' 

 tation being picked out with darker brown. 



Abdomen dull black, clothed icith short dark hairs, usually
