358 HAMINEA. 



More cylindrical and elongated than H. solitaria, with the colu- 

 mella more concave. 



H. ANTILLARUM d'Orbigny. PL 41, figs. 35, 36. 



Shell fragile, subtranslucent, globose-ovate, narrower above, swol- 

 len below ; color pellucid-horny, or slightly green tinted. Surface 

 seen under a lens to be marked by growth striae ; and under a high 

 power fine, close, rather effaced and wavy spiral striae, but this is 

 hardly seen with the ordinary hand lens. Vertex narrowly im- 

 pressed, imperforate, the slightly thickened outer lip arising from 

 the right side of the center, produced high above the vertex ; outer 

 lip produced forward above. Aperture more than twice as wide 

 below as above ; columella very concave ; parietal callus light. Alt. 

 10, diam. 7-8 mill.

The typical H. antillarum is a small shell, nearly white in color. 

 It is abundant on the west coast of Florida. If. cerina Mke. is, I 

 believe, absolutely synonymous. 



Var. GUADALUPENSIS Sowerby. PL 41, figs. 30, 31, 33, 34. 



Shell thin, but rather solid, globose-ovate, distinctly compressed 

 above, swollen below; the vertex narrow, concave in the middle. 

 Color greenish-yellow, subtranslucent when young, rather solid and 

 opaque when adult. Surface having irregular growth wrinkles, 

 often even plicate above in adults, and showing under a strong lens, 

 excessively fine, close and somewhat wavy spiral strice. Outer lip 

 slightly thickened toward its apical insertion, where immediately to 

 the right of the imperforate center of the vertex it is connected by a 

 short vertical curve with the parietal callus. It rises high above the 

 vertex, sweeps forward, and then as it descends, backward to the 

 broadly rounded basal lip. Columella extremely concave, with a, 

 very narrow white callus, making a small fold above ; parietal cal- 

 lus light. Alt. 18, diam. 14 mill.
