to L. striatula Gld., by various authors. L. acuminata is 

 smoother, more slender, with a longer and narrower aperture 

 and a weaker columellar fold. L. striatula is smaller, with 

 more pronounced costas and a flatter base. 



Specimens, from Makaweli, measure 12.0 x 4.5 mm. They 

 differ in that the aperture is more diagonal, the suture is 

 usually accompanied with a reddish line and the last whorl 

 ascends more abruptly than in specimens from the type 

 locality (Haleieie). 



Specimens from Ekaula are more cylindrical in form and 

 have an almost perpendicular aperture. Those from 

 Hanalei measure 10.0 x 4.6 mm. The spire is more turrited 

 and the aperture less diagonal. 



Unlike most Leptacliatinas this species has a tubular colu- 

 mella, which is almost straight. The young have a rather 

 large, circular umbilicus.

There are two color varieties of this species. The color 

 variety, described by Pease (pi. 7, figs. 30, 31, copied from the 

 original figures, and fig. 27) with a broad reddish brown band 

 is rather uncommon ; a unicolorous brownish corneous variety 

 (fig. 28) is more abundant. Shells from Puukapele are
