the suture and periphery, and with a spiral band of dark brown at 

 the base, somewhat diffused, with the white band at the periphery ; 

 keeled ; rather blunt at the apex ; whorls 5, nearly flat, the last con- 

 vex at the base ; aperture oblique, rhomboidally ovate ; peristome 

 dark brown, moderately thickened, margins approximating, the 

 right slightly deflected, the columellar margin reflected and furnished 

 with a straight callus. (Brazier.) 



Alt. 14, greater diam. 16, lesser 13 mill.

 p. 301. 



Varieties of this species occur in which the dark brown band is 

 occasionally found above the chalk-white one, and a brown band 

 under the periphery. (J5mz.) 



H. DAMPIERI Angas. PI. 5, fig. 88 ; pi. 16, fig. 18. 



Shell imperforate, subglobose, conoid, light brown or fawn color, 

 here and there minutely dotted with dark, gray specks with a broad 

 white band around the middle of the penultimate whorl, and two 

 upon the last, one above and the other below the middle, also a nar- 

 row white line revolving up the spire beneath the suture, and a dark 

 brown zone surrounding the pale or yellowish umbilical region. 

 Whorls 5, a little convex above, somewhat glossy, obliquely and 

 very finely striated by the lines of growth ; the last more or less con- 

 centrically striated beneath, shortly descending at the aperture, 

 which is white within. Lip a little thickened, edged with reddish- 

 brown, only slightly expanded on the right side, more dilated below, 

 produced into a thin, transparent callosity over the umbilical region, 

 united above to the upper extremity of the peristome. Columellar 

 margin oblique, white or partly tinged with reddish-brown, thickened 

 and terminating below within the edge of the lip. Alt. 19, greatest 

 diam. 22, smallest 19 mill. (Smith.')

H. dampieri ANG., P. Z. S. 1869, p. 47, t. 2, f. 6. PFR., Mon., 

 vii, p. 310. SMITH, P. Z. S. 1885, p. 592, t. 36, f. 5. 



The specimens collected by Guppy and described by Smith are 

 smaller than the types ; they also have the peristome brown, and 

 the basal band is darker (pi. 16, fig. 18).
