I have also at this opportunity sketched, pi. IV, fig. 5, a fragment 

 of a Brass Celt which was shown to me near Moulmein, and was re- 

 garded by me as of doubtful authenticity. 



A short discussion followed the reading of this paper. 



Dr. Stoliczka said that one or two of the forms of implements with 

 uniformly attenuated sides (fig. 3, pi. IV,) appear to have their perfect 

 analoga in the later stone age of Europe, where polished stone imple- 

 ments came in use, instead of the older rude ones. The nature of the 

 rock, being basalt or schist, certainly did not allow their being used in 

 clearances or the like purposes in the jungle, and Mr. Theobald's sug- 

 gestion that they were more likely employed in rice cultivation is no 

 doubt much more probable. 



The President drew attention to the very peculiar form of these 

 implements, being evidently manufactured for certain purposes. Their 

 most remarkable appearance, quite distinct from European forms 

 of the kind, consists in the sharpened edge on one side only which 

 most of them possess. This, lie believed, lias not been noticed in any 

 of the implements found in Europe. 



IV. — Notes on Indian Mollusca. Descriptions of new species of Di- 

 plommatina from the Khasi hills ; by Captain H. H. G-od win- 

 Austen, R K. G. S. — communicated by Dr. Stoliczka. 



Captain Godwin-Austen has for years given attention to collecting 

 Landshells in various parts of India, and to carefully observing their 

 animals. He has contributed several interesting novelties to Mr. W. 

 T. Blanford's well-known " Contributions to Indian Malacology." Late- 

 ly, however, Captain Godwin-Austen obtained a large number of 

 new species in the Khasi hills, and this has induced him to 

 open with the present contribution a scries of papers " on Indian 

 Mollusca." Four new species and a very interesting variety of 

 D. polypleuris have now been described by the author. The notes 

 regarding the animals of these species are especially interesting, be- 

 cause we as yet know very little of the animals of the Cyclostomacejj, 

 and allied forms.
