ON NEW AND RARE BRITISH ARACHNIDS. 129 



organs drawn by Dr. A. R. Jackson, which will perhaps 

 serve for its better identification. The identity of 

 Leptyphantes patens with Opistoxys subacuta was 

 unsuspected at the time when the former was described, 

 chiefly owing to the palpal organs of L. patens having 

 been forced out of their natural position. Dr. Jackson, 

 who has carefully examined and compared both the 

 types, first suggested to me their identity. 



Centromerus (Tmeticus) abnormis, Blackw. 



Linyphia abnormis, Bl. ; Cambr. Spid. Dors., 



pp. 207 and 578. 



Adult males were found in Bere Wood towards the end 

 of May, 1913, by my son (A. E. LI. P.-C.) 



Centromerus (Tmeticus) expertus, Cambr. 



Tmeticus expertus, Cambr., Spid. Dors., p. 203, 



and Proc. Dors. F. Club IV., p. 152. 

 This species, though widely distributed, seems to be a 

 local and rare one. An adult of each sex was found at 

 the end of November, 1913, on the outside of a copse at 

 Bloxworth, among herbage, by my son (A. E. LI. P.-C.) 



Leptorhoptrum (Tmeticus) Huthwaitii, Cambr. 



Neriene Huthwaitii, Cambr., Proc. Dors. F. Club 



X., p. 118, 1889. 

 Tmeticus Huthwaitii, Cambr., Proc. Dors. F. Club 



XXVI., p. 47, 1905. 

 Leptorhoptrum Huthwaitii, Cambr., Kulczynski, 



Aranese Hungarian II., p. 79, Tab. III., fig. 20. 

 An adult male of this fine and widely distributed 

 species was sent to me from Yorkshire in August, 1913, 

 by Mr. W. P. Winter. This spider is certainly out of 

 place in the genus Tmeticus ; its place is in the new 

 genus formed for it by Kulczynski (I.e. supra).
