 Leptachatina (Labiella) callosa SYKES, Fauna Haw., ii, 1900, 

 p. 358. 



This species is represented, as far as I know, by the single 

 type specimen in the British Museum. It is very closely re- 

 lated to L. labiata Newc., and may ultimately prove to be an 

 unique specimen of this species. The spires of both species 

 are identical. The only differences are that L. callosa is 

 larger and has a different shaped aperture.

 white, strongly lamelliform; aperture truncately auriform; 

 peristome somewhat labiate, white or reddish ; dextral margin

 nate; parietal margin thin, dark corneous. Length 13.0, 

 diam. 6.6, length of body whorl 9.0 mm." (Gulick.)
