Oahu: on a taro patch embankment west of the Oahu raih'oad, 

 about a half mile west of Waipahu station, Pilsbry, 1913, Type 

 116610 A. N. S. P. 



Only found fossil in earth dug out of the taro field probably Pleis- 

 tocene. It is related to A. cylindrica (Helbl.), but in the present 

 species the upper part of the aperture is narrower, the excavation of 

 the summit deeper with angular margin; the base is more effuse, and 

 the columellar callus is more raised, the groove bounding it being 

 wider.

Haminea ■pusilla Pse., P. Z. S. 1860, p. 20; description repeated in Man. 

 Conch. XV, p. 364. 



This species was described by Pease in his earlier manner, Linnean 

 in brevity. It is not present in his collection in the M. C. Z., but 

 his allusions to its small size, solidity, cancellated surface and um- 

 bilicate apex apply well to a small shell which has been taken in 

 several localities. 



The shell is solid, nearly cylindric in the middle, contracting 

 rather abruptly towards the ends. It is whitish with an ill-defined 

 white band near the: base, some indistinct brownish markings above 

 it. The surface has strongly impressed spiral lines throughout, the 

 intervals cut by much finer, shallower, close axial impressed lines, 

 hardly visible except imder the microscope. The aperture is very 

 narrow in the upper two-thirds, but dilated somewhat below. The 

 outer lip rises well above the vertex, which is narrowly, deeply um- 

 bilicate; outer margin rather straightened. Columella nearly 

 straight and having a very slight fold.
