LIMNiEID^. 887 



This small species, well characterized hy its remarkable columeUa, is unlike any 

 Indian species ; the figure that it most resembles in ' Klister's Monog.' is a var. 

 of L. peregra, pi. iii, figs. 17, 18 ; there is no shell like it figured in the ' Conch. 

 Iconica' ; probably L. andersoniana will prove to be a common species throughout 

 Southern China. 



The late Dr. StoKczka collected a perfectly identical form at Yarkand, as well 

 as a variety at Kashgar, the latter interesting as possessing a very small umbilicus ; 

 L. andersoniana appears to be next allied to L. pervia, Mart. (? = L. davidi, Desh.), 

 and will requu-e further comparison with type specimens of the two latter. 



Long. 10, diam. 6J ; apert. long. 7^, diam. 3 J mm. 



Abundant at Sanda and Nantin, in Yunnan. 



LlMN^A TUNNANENSIS, Ncvill. 

 Limncea yunnanensis, Nevill, Journ. As. Soc, Bengal, vol. xlvi, 1877, p. 26. 



Shell medium-sized, ovately oblong, imperforate, pale horn-colour, very fragile, 

 spire acuminate ; whorls three to four, last whorl remarkably small ; columella very 

 strongly twisted and much produced; aperture very elongate, contracted anteriorly, 

 broadly and beautifully regularly rounded at base. 



This species is closely allied to the shell figured by H. Adams,^ as L. swinlioei 

 from Formosa ; it also resembles pi. IV, fig. 256, in the ' Conch. Iconica,' but not 

 fig. 25a, which belongs apparently to a distinct species ; L. ytmnanensis may 

 eventually prove to be an extreme variety of i. swinhoel, characterized by the 

 smaller body- whorl, by the aperture being more contracted anteriorly and more 

 rounded posteriorly, finally by the slightly more twisted columella. I have little 

 doubt that i. swinlioei itself is only a synonym of L. flava? A shell sent to 

 the Indian Museum by M. Morelet under the latter name, from China, agrees ex- 

 actly with Mr. Adams' figure I. c. ; Sowerby in the ' Conch. Iconica,' records and 

 figures a species as L. flava, Mori. ? 



Long. 16, diam. 10 ; apert. long. 11^, diam. 7 mm.
