This small species, well characterized by its remarkable columella, is unlike any- 

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

 of Z. 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. Stoliczka 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. (? = Z. davidi, Desh.), 

 and will require further comparison with type specimens of the two latter. 



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



Abundant at Sanda and Nantin, in Yunnan. 



LiMNiEA TUNNANENSIS, NcviU. 

 LimncBa 1/unnanensis, 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. swinhoei 

 from Pormosa ; it also resembles pi. IV, fig. 25&, in the ' Conch. Iconica,' but not 

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

 eventually prove to be an extreme variety of L. swinhoei, 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 L. swinhoei itself is only a synonym of L. flava? A shell sent to 

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

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

 figures a species as X. flava, Mori. ? 



Long. 16, diam. 10 ; apert. long, llj, diam. 7 mm. 



At Sanda, in Yunnan.
