curved. Outer lip thin, corresponding in curvature to the left outline 

 of the body whorl. Surface marked by fine incremental lines and 

 very fine, closely and evenly spaced, wavy, spiral striations. Aperture 

 narrow, scarcely at all widened posteriorly, and very slightly so 

 anteriorly. Parietal callus forming a thick rounded fold anteriorly. 

 Gould's type, Cat. No. 164, U.S.N.M., was collected by William 

 Stimpson, on the North Pacific Exploring Expedition at Simons 

 Bay. It measures: Length, 8 mm.; diameter, 2.6 mm. Cat. No. 

 249801, U.S.N.M., contains another specimen from Port Alfred 

 (Coll. No. 1073).

BULLARIA, species? 



Cat. No. 249797, U.S.N.M., three shells from Port Alfred, too imma- 

 ture to make identification positive (Coll. No. 1069).

HAMINEA ALFREDENSIS, new species. 



Plate 1, fig. 5. 



Shell irregularly pear-shaped, thin and translucent, light greenish 

 yellow. The anterior portion of the outer lip projects considerably 

 above the spire and stands off quite a distance from the parietal wall 

 posteriorly, and very much anteriorly where it becomes quite patu- 

 lous. The shell has a somewhat pinched appearance at the middle of 

 the anterior half, which renders that portion flattened or even slightly 

 concave. Base well rounded. Aperture very large; columella very 

 strongly curved, reenforced at the edge by a narrow, reflected callus 

 which expands and spreads over the interior of the lip at its anterior 

 extremity; parietal wall covered by a callus. Entire surface marked 

 by fine incremental lines and exceedingly fine, closely spaced spiral 

 striations. 



The type measures: Length, 12.4 mm.; diameter, 10 mm. It and 

 another specimen come from Port Alfred, they are entered as Cat. 

 No. 186656, U.S.N.M. (Coll. No. 10). 



The present form differs from natalensis Krauss in having the 

 posterior half of the spire flattened instead of evenly rounded, which 

 gives alfredensis a pear-shaped outline while natalensis is oval.
