parietal lamellae form one continuous lamella, as seen from 

 the base, the angular projecting slightly at their junction. 

 The columellar lamella enters horizontally. The peristorne is 

 continuous and forms a raised ledge across the parietal wall. 

 This peculiarity, together with the conic shape, gives the shell 

 much the aspect of Boysidia ; but as the columellar lamella 

 does not descend inwardly, and the basal fold is subcolumel- 

 lar in position, it is nearer the subgenus Sinalbinula, in Gas- 

 trocopta, though in some degree transitional. Length 3.35, 

 diain. above aperture 1.65 mm. ; 5 whorls.

Shell riinate, ovate-oblong, subcylindrical, hyaline, glossy, 

 the apex obtuse. Whorls 5, convex. Aperture ovate-rotund, 

 5-plicate. Peristome a little expanded, the margins joined by 

 a thin callous. One irregular, sinuous parietal fold, two colu- 

 mellars, and two deeply-placed palatals. Length 11/2, width 

 scarcely 1 mm. (Benson).

This species is very close to G. anni<t< rella of China and 

 Japan, but is distinct by the swcillcr size, absence of a supra- 

 palatal plica, very small or wanting infraparietal tubercle, 

 and the larger columellar lamella. The figure of a Simla 

 specimen is copied from Conchologia Indica (pi. 21, fig. 17). 

 I have not seen topotypes, those figured (pi. 21, figs. 15, 16)
