Conical, obscurely ribbed on tbe upper part of the whorls, with a 

 blunt keel on the angle, and another more or less distinct below; 

 outer lip expanded in the centre and lower part, confluent with the 

 columella, operculum horny. Of the synonyms quoted above, 

 fasciata and variabilis were pre-occupied, ftava was given to one of 

 the varieties on the supposition of its being a distinct species, and 

 on that account is thought unsuitable. Common in woods, upon 

 trees and green leaves, in Bahia.

Resembling the last in general form, but smooth, -with the outer 

 lip scarcely reflected ; the inner lip slightly thickened ; the colour 

 varies from light yellow to dark brown, operculum horny.

Globose, smooth ; whorls round, elevated near the suture ; 

 aperture semi-lunar; outer lip expanded, the upper part de- 

 pressed ; columella small. Varieties occur as follows, — yellow, 

 yellow banded with brown, brownish white with broad brown 

 bands, brownish white with brown bands and spots between ; the 

 last variety being named picta by Pfeiffer. Callajabas, Cuba, 

 Matanzas.

T. H. variegatse simili, sed magis depressa ; anfractibus minus 

 distinctis; labio externo magis expanso et reflexo. 



This shell resembles the last ; it, however, is more compressed, 

 the upper part of the whorls are less elevated, the outer lip and 

 columella more flattened and expanded. West Indies.

T. depressa, laevi ; anfractu ultimo magno ; labio externo sub- 

 expanso; columella obliqua, confluenti. 



Depressed, smooth, with the last whorl large; the outer lip 

 rather expanded and obliquely confluent with the columella. Co- 

 lours varying, but generally arranged in bands. This is the shell 

 which Gray has figured as H. fasciata. Lam. Its identity, how- 

 ever, appearing doubtful, we have applied the name given by De 

 Ferussac, Martinique and Jamaica.
