132 ON NEW AND RARE BRITISH ARACHNIDS. 



Gongylidium retusum, Westr. 



Erigone retusa, Westr. Aranese Suec., p. 253. 

 Neriene retusa, Westr. -Cambr., Spid. Dors. p. 116. 

 An adult male was found at Bloxworth Rectory by my 

 son (A. E. LI. P.-C.) Aug. 3rd, 1913, and another by Dr. 

 Haines at Arne. It is still a rare spider in Dorset. 



CORYPHAEUS, F. 0. P. -Cambr. 



The genus Coryphaeus was established by the late 

 F. O. Pickard-Cambridge for the reception of a spider 

 found near Carlisle. (Ann. and Mag. N. H., ser. 6, 

 Vol. XIII., 1894, p. 87). This spider (Coryphaeus 

 glabriceps) afterwards turned out to be identical with 

 Gongylidium distinctum, Sim. M. Simon subsequently 

 transferred his G. distinctum to the genus Hilaira. 

 (Hist, des Araignees I., 701). This last is, it seems to me, 

 quite untenable, and thus Coryphaeus becomes a good 

 genus, with C. distinctus, Sim., as its type.
