cies, but there is not the slightest ground for a separation. A specimen 

 before me has an indistinct band above, and the col umella and pari- 

 etal wall are of a blackish-chestnut color (pi. 16, figs. 25, 26). Pfeif- 

 fer and Dohrn give Admiralty Is. as the locality of the species, but 

 those before me are from the Solomons, and I am disposed to think 

 the other locality doubtful, it being taken from the Curning 

 collection. 



H. BOYERI Fischer & Bernard!. PL 13, figs. 48, 49. 



Imperforate, trochiform, rather solid, obliquely striate and decus- 

 sated with undulating, forward-descending striae. Whitish and 

 tawny clouded. Spire turbinate, rather obtuse, whorls 5i, convex, 

 the last descending in front, sub-carinated and banded with white 

 below the middle ; base little convex. Aperture very oblique, sub- 

 rhombic, white within ; columella entering, compressed, flexuously 

 sloping, surrounded with rosy ; peristome white, right margin nar- 

 rowly expanded, basal margin reflexed, forming an obtuse angle 

 with the columella. 



Alt. 22-23, greater diam. 27-29, lesser 22-23i mill. (F.&B.)

H. PH^OSTOMA Martens. PI. 7, figs. 33, 34. 



Imperforate, trochiform, thin, striatulate, obsoletely wrinkled- 

 malleate, a little shining ; isabelliue, painted with zigzag streaks of 

 blackish-brown, often interrupted ; spire conical, elevated ; whorls 

 5, a little convex, the earlier 2 unicolored, diaphanous-corneous, the 

 third carinated at the suture, the last whorl rounded at the periph- 

 ery and having a wide white band there ; below the middle flattened 

 and concentrically striolate. Aperture subdiagonal, elliptical, cut by 

 the adjacent body-wall ; peristome broadly expanded, basal and 

 outer lips white, the columellar lip brown, dilated, appressed ; throat 

 brownish. Alt. 25, greater diam. 28, lesser 20* mill. (Mart.)

Allied to H. gaberti but rounded, not angular, at the periphery. 

 Pfeiffer's figures of H. gaberti agree with this species in the rounded
