ture rather wide, outer lip slightly arched, somewhat acuminately 

 produced above, expanded below, columella nearly straight, re- 

 flected, producing behind it a minute umbilicus. Length 3 lines, 

 breadth H lines, alt. 1} lines (!>.).

 mud and broken shells.

May prove to belong to Atys, but as it is unfigured and not seen 

 by me, I do not venture to alter Mr. Brazier's generic reference. 



This species differs very much from Haminea ambigua (A. Ad- 

 ams), the center of the shell being smooth, and each end having 

 eight deep transverse engraved lines, whereas H. ambigua is en- 

 tirely transversely striated.

Shell elongate-cylindrical, above and below roundly quadrate, 

 thin, white ; covered with a whitish epidermis, shining, buff tinged 

 toward base and vertex ; having growth lines, and above and at 

 base subdistantly transversely striated. Aperture rather wide, di- 

 lated at base, scarcely produced above the vertex ; columella short, 

 rather straight, reflexed, covering the umbilical region, joined with 

 the vertex by a very thin scarcely shining callus ; lip thin, inserted 

 in the middle of the vertex and thickened there. Alt. 14, diam.

The lateral outlines of this species are nearly straight ; the supe- 

 rior striae are about six in number, the inferior about eighteen. H. 

 papyrus A. Ad. is its nearest ally ; but it is narrower, more elon- 

 gate, with the striae not covering the whole of the shell, the vertex 

 is more depressed and the aperture is less broadly dilated and more 

 effused at the base ($.). 



This species belongs to a group of forms somewhat similar to cer- 

 tain species of Cylichna and Atys, like H. decora Braz. and papyrus
