Perhaps a form dwarfed by unfavorable conditions, but 

 recognized by the senior author in MSS. as a distinct species. 

 Some examples without definite locality in coll. A. N. S. P. 

 are rather solid with thickened lip. Its range lies on the ex- 

 treme northwestern border of the known range of A. textilis. 



13&. A. textilis kaipaupauensis n. subsp. PL 38, fig. 12. 



The shell is short, subperforate, thin, with straightly conic 

 spire and convex whorls, the last quite rotund ; dull purplish- 

 brown, the thin cuticle yellowish on the early whorls. Em- 

 bryo finely striate ; later whorls with fine, irregular sculpture 

 of growth-wrinkles. Aperture purplish within, the lip very 

 narrowly thickened. Columellar lamella thin, its lower edge 

 Bubhorizontal. Length 11, diam. 7.1, aperture 6 mm. ; 5% 

 whorls.

Near the above, yet with narrower, straightly conic spire 

 and more convex whorls. Type to be deposited in the Bishop 

 Museum. 



14. A. GULICKIANA n. sp. PL 38, fig. 8. 



Shell narrowly perforate, globose-conic, rather solid, glossy, 

 without dull or deciduous outer cuticle. Spire very short, its 

 outlines very slightly convex, nearly straight, the summit ob- 

 tuse. Embryonic whorls nearly smooth, the first dull purple, 

 the rest covered with a thin, light greenish-yellow cuticle, be- 

 coming reddish-brown on the latter part of the last whorl. 

 Embryonic whorls apparently smooth, rather convex ; follow- 

 ing whorls lightly marked with growth-striae, less convex, the 

 last whorl subglobose, subangular in front of the aperture, 

 becoming rotund in the last two-thirds. Aperture somewhat
