 broad, of an olive or greenish or reddish brown colour ; 

 below the oblique plaits on the upper half of the whirls is a 

 double row of granules, and the margin has only a single 

 row of spines; it is nearly allied to, and probably not speci- 

 fically distinct from, T. ccdatus.

 bricated, transversely granulated whirls, ob- 

 tusely plaited on their lower margins ; base

 Favanne. 



Shell about an inch and three-quarters long, and an inch and a 

 half broad, and differs from T.fenestratus principally in be- 

 ing larger and in having the whirls imbricated. Favanne 

 doubts whether it is more than a variety of that species, and 

 Kjemmerer considered both to be only varieties of T. denta- 

 tus. See Cab. Rudolst. p. l6l.

 transversely granulated whirls, obtusely plait- 

 ed on their lower halves; base flat, and the
