!2 NOTES ON BRITISH SPIDERS. 



to the conclusion that these are identical. This is the more 

 satisfactory, as clearing up one at least of Mr. Blackwall's species, 

 of which the types have unfortunately been destroyed. 



FAM. LYCOSID.E. 

 TROCHOSA CINEREA, Fabr. 



Trochosa cinerea, Fabr. Cambr., Spid. Dors., p. 545. 

 Adults of both sexes of this fine spider were found in abund- 

 ance on the banks of the Severn, and kindly sent to me by 

 Mr. L. Greening, of Warrington, in August, 1898. 



TARANTULA FABRILIS, Clk. 



Araneus falrilis, Clerck. Cambr., Spid. Dors., 368. 



Adult males; rare, Bloxworth Heath, September yth, 1898. 

 The burning in 1893 f tne heath-district, where alone this spider 

 has yet been found in Britain, almost exterminated the species. 



FAM. SALTICID.E. 

 HASARIUS ADANSONII, Aud. 



Hasarius Adansonii y Aud. Cambr. Spid. Dors., 566, and also 

 Proc. Dors. N.H. and A.F. Club, XVI., p. 120, &c. 



Adult and immature examples of both sexes occur pretty freely 

 in green-houses and stoves at the Royal Gardens, Kew. One or two 

 were also found out of doors during the past summer, so that 

 possibly it may one day become acclimatised. 



HASARIUS NICHOLSONII, Cambr. 



Hasarius Nicholsonii, sp. n., fig. i. 



Numerous examples of both sexes, adult and immature, from a 

 hot-house at Kew, no doubt originally imported with tropical 

 plants. It is a fine and very conspicuous species, and, appearing 

 to be new to science, I have given it the name of the discoverer. 

 Its genus can hardly be said to be as yet quite certain. I have 

 sent examples both to Mr. Peckham (of Milwaukee, Wiscon,, 

 U.S. Amer.), who has made a specialty of this family, and to 

 M. Simon. The former considers it to be a Plexippus>
