also found on dead leaves and twigs. Jt is usually taken in 

 rather open country but has also been found in damp forest 

 patches as well as in talus in open situations. A basal view 

 of a young specimen is drawn in pi. 26, fig. 8. 



It is easily separated from L. mirabilis by its lighter color, 

 fewer and more widely spaced costse, its broader outline, the 

 continuous lower palatal fold and the additional lamellse in 

 the aperture.

''Shell sinistral, dark brown, cylindrically oblong, except 

 for the apex regularly and obliquely sculptured with distant 

 acute lira?, scarcely shining, rimate-perforate. Spire obtuse. 

 Whorls 6, regularly increasing, convex, with an impressed 

 suture; the last inflated in front of the aperture, afterwards 

 broadly slightly constricted, hardly attenuate, impressed at 

 its middle, somewhat compressed at the umbilicus. Aperture 

 scarcely oblique slightly projecting towards the right at the 

 base and externally towards the outer and upper margin, 

 extended, armed on the parietal wall with a marginal and 

 short dentiform lamella near the upper angle ; a second, the 

 parietal, much larger, deeply seated and nearly median ; a 

 deeply seated strong columellar fold (only seen when viewed 

 obliquely), and 2 palatal lamella^, the lower of which is gutti- 

 form, short, deeply seated, the upper long and extending to

Ancey described this species from a single specimen and 

 without exact locality. As his specimen came from the aper- 

 ture of a specimen of Ach. mustelina, the Waianae Range is 

 undoubtedly the original locality. L. mirobilis is distributed 

 over nearly the whole range. It is very abundant among dead
