144 ON NEW AND RARE BRITISH ARACHNIDA. 



somewhat comb-like process (PI. B., Fig. 47, b], connected with 

 the palpal organs (which I have found in all the numerous males 

 I have examined of T. silvaticus} is absent in T. serratus. The 

 paracymbium also is larger than in the latter, and differs in form, 

 and its serrations on the outer margin are more minute. 



The female has the genital aperture and process of a somewhat 

 similar general form to that of T. silvaticus, but is broader from 

 back to front in proportion to its width, and differs also in 

 other details. 



An example of each sex was received in 1902 from Mr. W. 

 Falconer among specimens of T. silvaticus, Bl., found near 

 Huddersfield. It has not before been recorded as a British 

 species, but may easily have been overlooked among examples 

 of T. silvaticus, Bl.

Diploeephalus protuberans, Cambr. A. R. Jackson, Proc. 

 Chester Soc., May, 1907, Part vi., No. i., p. 3., Fig. 10-15. 



This species is nearly allied to D. latifrons, Cambr., but may 

 easily be distinguished by both the form of the caput and the 

 structure of the palpi and palpal organs. The only British 

 example yet recorded is that mentioned by Dr. A. R. Jackson 

 (I.e. supra) found at Gibside, Durham, by Mr. R. S. Bagnall. 

 The figs, in PI. B. are taken from those in Proc. Zool. Soc. 

 (I.e. supra).
