Achatinella marginata GU-LICK, Ann. Lye. N. Y., vi, 1856, 

 p. 179, pi. 6, fig. 7. Achatinella succincta NEWCOMB, Ann. 

 Lye. N. Y., vi, 1858, p. 334. Achatinella (Leptachatina) 

 succincta PFR., Mon. Hel. Viv., vi, p. 183. Leptachatina 

 marginata SYKES, Fauna Haw., ii, 1900, p. 366. 



"The most striking character of this species is the broad 

 sutural margin, in which respect it is unlike other species 

 of this group." (Gulick.) 



The only specimen of this species which I have been able 

 to find is in the collection of the Boston Society. There is 

 no doubt but that it is more or less closely related to L. suc- 

 cincta but, as Sykes has remarked, it "is smaller and more 

 slender. ' '

 lamelliform; aperture nearly vertical, elliptical; peristome 

 simple; with dextral margin regularly curved, unreflected; 

 columellar margin dilated, thin, adnate ; parietal margin very-
