Snout thick, projecting, no pores or lateral lobe ; mouth trans-

 off both jaws which have sharp edges, but no horny covering. 

 Rostral barbels two-thirds as long as orbit. 



Tins. — Dorsal commences midway between the snout and the 

 posterior margin of the base of the anal. Caudal deeply forked, 

 upper lobe the longest. 



Lateral line: — 3J rows of scales between it and the base of the 

 ventral fin.

Notes on terrestrial Mollusca from the neighbourhood of 

 Moulmein (Tenasserim Provinces), with descriptions of new 

 species, — by Dr. F. StoliczkA, Paleontologist, Geol. Surv. of 

 India ; lion. Secy. Asiat. Soc. Bengal* 



(With 8 plates.) 

 [Received and read 5th January, 1871.] 



The following observations are offered on a small collection of 

 Mollusca made, during the month of August 1869, in the neigh- 

 bourhood of Moulmein, Tenasserim Provinces. It is not my in- 

 tention to give a complete list of all the shells which have been 

 described from that neighbourhood, — though such may at some 

 future time prove to be a very desirable acquisition, — but merely to 

 restrict my remarks to those species which I have myself collected, 

 particularly with reference to some points in the anatomy of the 

 animals. 



The land shells of this part of the Malayan country received 

 early attention through the collecting zeal of the Rev. Dr. Mason, 

 Capts. Sankey and Gordon, Mr. Theobald and many others. The 

 materials have been chiefly worked out by Dr. A. Gould, Mr. 

 Benson, and Mr. Theobald.
