DESCRIPTIONS OF SOME NEW SPECIES OF SPIDERS 
FROM BRITISH INDIA. 
By R. I. Pococs, or tax British Museum or Natura History. 
(Read before the Bombay Natural History Society on 9th October, 1900.) 
THE descriptions contained in the following pages are based toa 
large extent upon materials kindly forwarded to me through Messrs. 
H. M. Phipson and R. C. Wroughton, by various members of the Indian 
Forest Service and of the Bombay Natural History Society. The 
descriptions were drawn up for publication in a volume upon the 
Arachnida of India, forming part of the Fauna of India Series, But, 
unfortunately, exigencies of space compelled me to omit them from 
the volume, together with the diagnoses of many previously established 
species. 
I hope at some future time to be allowed to publish in this Journal 
illustrations of the essential characters of the species here described.
