exceedingly remarkable and unmistakable one. It is 

 widely distributed, but so far as known still a rare 

 species. 



Tigellinus furcillatus, Menge. 



Wideria nigriceps, Cambr., Proc. Dors. F. Club, 

 Vol. XIV., p. 157 (and other references there 

 quoted). 



I have never until lately been able to identify satisfac- 

 torily any male spider of which W. nigriceps might be the 

 female. My son, A. E. LI. Pickard-Cambridge, has, 

 however, found female examples lately at Bloxwor h, 

 and with them the male of T. furcillatus, Menge. From 

 these I have come to the conclusion that W. nigriceps, 

 Cambr., is undoubtedly the female of T. furcillatus 

 Menge. 



Ceratinella seabrosa, Cambr. 



An adult male on iron railings, Bloxworth Rectory, 

 taken by R. J. Pickard-Cambridge, May 17, 1911.

An adult male taken by Dr. Jackson on Bloxworth 

 Heath, September 26th, 1911, close to the spot where 

 many years ago (September, 1878) an example of the 

 same sex was found by myself : since then, besides the 

 present record, it has only been found here once (vide I.e. 

 supra). The egg-cocoon has, however, been found by 

 myself, though at some distance from the above locality. 

 (See Proc. D. F. Club, XVIII., pi. A, fig. 7.) It appears 

 to be not only a very rare but also a very local species.
