With reference to the geology of the Jaintia hills, Col. Strachey asked, 

 whether any of the fossils which have "been found in the Nummulitic 

 limestones of Assam and the Eastern Provinces of Bengal, were identical 

 with those of the Western Himalaya, as for instance near Subathoo. 



Dr. Stoliczka said that of those species of fossils which he had the op- 

 portunity to examine from Assam, there were about 80 per cent, of them 

 identical with those found in similar beds in the North-west Hima- 

 layas, the Salt-range and Sind. In fact there is a remarkable similarity 

 to be noticed in the fossils of the nummulitic series from India through 

 Persia, Asia Minor, Transylvania up to the Carpathian Mountains. A 

 large number of the same species of Nummulites, the same Gonoclypus 

 and others are met with throughout. There are, however, above the 

 Nummulitics in Assam, more recent sandstone beds which contain a 

 perfectly different marine fauna, probably representing similar beds 

 which appear to be more extensively developed in the adjoining 

 province of Burma. 



III. Contributions to Indian Malacology ',No. X. — Descriptions of new 

 species of Cyclopiiorid^, and of the genera Ennea and Streptaxis from 

 the hills of Southern and South-western India ; by W. T. Blanford, 

 Esq., F. G. S. &c, (Abstract). 



The new species described are entirely from the hills of the South- 

 western and Southern portion of the Indian Peninsula, and the majority 

 belong to the operculated land shells. The greater number have been 

 discovered by Captain Beddome, to whom is due almost all that is known 

 of the Mollusca, inhabiting the hill ranges south of the Pulneys. Three 

 species are from the collections made by Rev. Fairbank on the Pulney 

 Hills, from amongst which I have already described two species of 

 Diplommatince, both belonging to the group peculiar to the Indian 

 Peninsula. 



The first 3 shells belong to a new subgenus of Cyclophorus which 

 I propose to call Ditropis, from two strong keels which occur in all 

 the species. Some species have more, but all have these two keels, one 

 at the periphery, the other basal, separated by a smooth space. This 

 is of course an unimportant character by itself, though it appears to 

 be constant. The other peculiar characteristics of the type are the 

 vitreous structure and the thick operculum with rough free edges to 

 the whorls externally. The forms appear quite isolated, and although
