1832.] Proceedings of the Asiatic Society. 415 



In this interesting paper, both species are described as having a calcareous oper~ 

 culum, but the under-mentioned authorities describe the operculum of Paludina 

 as horny. 



" Un opercule orbiculaire et come" 



" Operculum orbiculare corneum" 

 are the expressions of De la March, and which would have been noticed by Du- 

 bois if incorrect. Dubois however contents himself by translating them "the 

 operculum homy and orbicular." Mr. Guilding, in his notices of the Zoology of 

 the Caribsean Islands, when speaking of the " Paludina Anetorum" says, " opercu- 

 lum corneum in dorso pedis." And some species found in Bengal have none other 

 than a horny operculum. 



Again ; — the author describes his first shell as " deeply umbilicated," and the 

 second, with " no umbilicus." On this part of the subject Mr. Guilding represents 

 the shell of tlie genus Paludina as " sub-umbilicata," a term well expressive of the 

 rudimental umbilicus formed by a slight reflection of the columellar lip towards 

 the body of the shell ; De la Marck affords negative evidence by making no men- 

 tion of any kind of umbilicus ; and in this country it occurs but in the slight 

 degree mentioned above. All concur in the rounding of the lower part of the 

 aperture. 



Upon the whole, therefore, these species do not appear entirely to agree with 

 the characters of any known genera ; but this is a point of too much importance 

 to be determined in the absence of an exceedingly minute description, both of the 

 animal and the shell, particularly of the anatomy of the former.
