DIAGNOSES OF SOME NEW INDIAN ARACHNTDA. 



By R. I. PococK (ZooL. Dept., Bretish Museum). 

 Tlie following paper contaius brief diagnoses of some new Indian 

 Arachnida^ kindly obtained for me by various members of the Natural 

 History Society of Bombay. I gladly avail myself of the opportunity 

 to thank all those who have been good enough to interest themselves in 

 the way of procuring material for me, but especially must acknow- 

 ledge my great indebtedness in this particular to Messrs. Phipson, 

 Millard and Wroughton. 



The species here diagnosed will be more fully described and dealt 

 with at greater length in a volume on the Scorpions, Pedipalpi, &c., of 

 British India, now in course of publication as part of the series on the 

 Fauna of India, edited by Dr. W. T. Blanford ; and I hope at some 

 future time to have the honour of laying before the Natural History 

 Society of Bombay a series of papers in which these and other Indian 

 species will be re-described, their habits discussed, and their more im- 

 portant structural details carefully illustrated, so that facilities may be 

 provided to naturalists resident in India for a further study of this 

 most interesting branch of the fauna.
