INTEODUCTION. 



Si:nce the last part was brought out in April 1907, a volume 

 of the ' Fauna of British India ' (MoUusca) has been completed 

 and published (June 1908). It treats only of two Families, the 

 Testacellidse and Zonitidae. This vokime was commenced by 

 Dr. W. T. Blanford, who wrote all the conchological portion 

 and some of the anatomical, at which I assisted ; after his 

 death I took up what was left to be done and brought it to 

 conclusion. The anatomical part is largely taken from the 

 writings of Dr. F. Stoliczka and from what has been published in 

 this work on the Indian Land MoUusca up to Part X., April 1907. 

 The Helicidse and other families remain to be done, but a great 

 deal of research work has to be accomplished first, to place species 

 in their proper famiUes and genera. There are a large number 

 of species to which even Family rank cannot be assigned with any 

 certainty, only examination of the animal is conclusive ; most of 

 these have to be collected and preserved, unfortunately they come 

 to hand very slowly. 



In spite of the great facilities for the study of Natural History 

 and the Biological courses open to young men at the present day, 

 it is surprising there are so few Couchologists and Malacologists
