222 ANNALS OF SCOTTISH NATURAL HISTORY 



LEPTYPHANTES BLACKWALLII, Kulcz. An adult male and several 

 females. These examples are rather remarkable, the male 

 especially, for their dark rich colouring and markings com- 

 pared with those met with in the south of England. It is an 

 abundant spider and found in most British localities. 



LEPTYPHANTES PALLIDUS, Cambr. Two adult females of this some- 

 what local but widely spread species. 



BATHYPHANTES VARIEGATUS, BL Adult and immature females. 

 In the north of England this very distinct little species is 

 abundant, but it is comparatively rare in the south. 



BATHYPHANTES CONCOLOR, Wider. Adults of both sexes. It 

 appears to be a common and universally dispersed British 

 spider. 



CENTROMERUS (Tmeticus) CONCINNUS, Thor. A single example of 

 the female. Further researches will perhaps result in the 

 relegation of this species into a variety only of C. (Tmeticus) 

 bicolor, BL Kulczynski considers it to be only a variety. 

 At present the form " concinnus " seems to be tolerably con- 

 stant, and recognisable without difficulty. I have given it 

 here as a Centromerus, a genus formed by Dahl with C. bicolor, 

 BL, as its type, and including others of the heterogeneous 

 group known hitherto under Tmeticus, Menge. This group, 

 though I have myself up to now kept it in its entirety, un- 

 doubtedly needs careful subdivision. 



TMETICUS HUTHWAITII, Cambr. Adult females. This would appear 

 to be a rather common spider in St. Kilda (as it also is in 

 some parts of England), but the male seems generally to escape 

 capture somehow. The adult male would probably be met 

 with early in spring, and later in autumn. 



Tiso VAGANS, BL A single adult male. Not a rare spider in 

 Scotland and England, but perhaps rarer in the south than in 

 the north. 



ERIGONE PROMISCUA, Cambr. Adults of both sexes. The female 

 has only recently been recorded (from St. Leonards-on-sea, 

 Sussex) ; but the males have occurred throughout England and 

 Scotland, and also in North Wales, though more numerously 

 in the north than in the south. 



DICYMBIUM NIGRUM, BL A single adult male, A common and 

 widely dispersed spider. 



SAVTGNIA FRONTATA, BL An adult male and two females. An 

 abundant spider in England, Wales, and Scotland. 



WALCKENAERA NUDIPALPIS, Westr. Two adult females. Some- 

 what local and rare, but widely dispersed in Scotland and 

 England.
