XXVIII. MOLLUS CA, II: ZONITIDAE AND 

 HELICJDAE (in part). 



By Lt.-Colonel H. H. God win- Austen, F.R.S. 



(Plates xxiii— xxiv.) 



The collection made by Mr. S. W. Kemp, Assistant Superin- 

 tendent, Indian Museum, when attached as naturalist to the Force 

 under Major-General Hamilton Bower, which entered the Abor 

 country in the winter of 191 1-12, is one of the finest and most 

 interesting from the Eastern Frontier I have ever looked over, 

 containing as it does so many genera and new species, and so 

 many that are quite distinct from the land mollusca at present 

 known from the most western part of Assam. 



As it must be a very long time before all this material, a very 

 large amount of which is beautifully preserved in spirit, can be 

 examined and the anatomical details worked out, I think it well to 

 give now a preliminary generic list of the species in the collection. 

 The description of new genera and new species to follow at inter- 

 vals. The first contribution I now submit treats of two interest- 

 ing new species Added to this collection I have received from 

 officers of the Indian Survey Department a small collection from 

 the Miri Hills which were entered the same season of 1911-12 by 

 a party under Lt. R. S. Wahab, R.E. 



Quite recently I have received many new shells collected 

 during 1912-13 by Lt. G. F. T. Oakes, R E., who has been extend- 

 ing his work in the Abor Hills of the previous year. Some of these 

 species of Spiyaciduin, Glessulu, Sirella, reached me alive and two 

 species of Glessuia at the time of writing (June) are still living. 



To both these officers and Mr. Kemp especially I am much 

 indebted and I sincerely thank them.
