A very common species, dull in hue, the smallest of the genus, 

 though occasionally of fair size. The largest I possess measures 

 55 mm., the smallest 32 mm. Uniformly narrow in shape, with ele- 

 vated spire, in marking it bears similitude to I/. no!>i7is, the square 

 body-whorl blotches being dull cinereous in this species instead of 

 the bright Indian red of fwdi/is, and the transverse lines on the 

 narrow ribs are almost identical. A variety is H. crassa Morch, con- 

 sidered by Sowerby (Thes. Conch., p. 171, pi. 233, f. 30, 31) a species; 

 it is brighter coloured, and much thickened, and broader, angled in 

 the upper part of the costae. Of this I have also an albino variety, 

 under name of solidiiJa A. Adams. 



The unique specimen of H. virginalis J. Gray,' admitted also by 

 Sowerby as a species, seems to belong here. It is an albino, with 

 intercostal riblets, quite regularly arranged. It is impossible to 

 judge of its merit without seeing the type. 



The name amouretta Bolten is not classical, but a French collo- 

 quial appellation. I therefore discard it as barbarous.

Described by Sowerby as being unique in the collection of Mr. 

 Hanley. This species is noted for the thin ribs, moderate size, and 

 fine spiral cancellations in the interstices between the ribs of the 

 body whorl. The ribs are distant. It is very probably the young of 

 one of the better-known species, but has been deemed by nearly all 

 past writers on the genus to possess good distinctive qualities, the 

 cancellations just mentioned being especially thus considered. Tryon, 

 indeed, makes H. striatula Ad. synonymous. This is usually sup- 

 posed to be the juvenile condition of H. veutricosa.
