Descriptions of new Mollusca from the Eastern Regions, — by 

 Messrs. Gr. and H. Nevill.

 (With Plate I). 

 We have already had the honor of laying before the Society 

 two papers, containing descriptions of new Mollusca from these 

 seas ; the present one contains descriptions of 12 new species of 

 marine shells from Ceylon, Mauritius and Pooree (Bay of Bengal), 

 for the several very interesting species from the latter locality, we 

 are greatly indebted to H. C. Eaban, Esq., C. S., who has 

 lately been successful in obtaining some more shells, of almost 

 equal interest, from Chittagong. We had also described, and pre- 

 pared a drawing, of a very interesting new species of Leptocon- 

 elms, but fortunately noticed, just in time, its description by 

 Lienard in the number of the French Journal de Conchiliologie 

 which we had just received ; as, however, no figure was given, we 

 have thought it desirable to take this opportunity of doing so ; 

 we have also named and described an interesting new species of 

 Cataidus from Ceylon, the smallest as yet known, a new species of 

 Pisidium from India and 5 new land shells from Mauritius and the 

 Seychelles. We have also given two figures of an interesting species 

 of Cypricardia, C. spat/mlata, described by Souverbie in the Jour-
