INTEODUCTION. 



After the lapse of ten years I am able to publish aDother Part of 

 this work. In this interval material has been accumulating and I 

 have described and examined a number of species belonging to many 

 genera found in India and the Malay Archipelago, and a large 

 number of drawings have been made which I hope to have the 

 opportunity of bringing out. The collection of Mr. Everett in 

 Borneo, so kindly placed at my disposal, has given me a further 

 insight into the interesting dififerences to be found and the degree 

 of relationship shadowed forth in the species of the Zonitidoe when 

 compared with those of India and the Malay Peninsula, and I shall 

 introduce some of these for comparison into the work. Since 1888 

 I have received very much kind help from, among others, Mr. M. A. 

 Ogle. In him I have to deplore the loss of a very dear friend and 

 an excellent zealous assistant when serving under me in the Survey 

 Department. He came to England for medical advice, terribly broken 

 in health ; but the best available could not save him, and he died in 

 London on the 4th April, 1892, at the age of 50, regretted by all under 

 whom he served, from the Surveyor-General downwards ; and he rests 

 after all his labours in ou!- quiet country cemetery at Shalford. I look 

 back to many pleasant days passed with him in the Assam Hills,
