This shell appears to be very nearly of the same size, and so 

 nearly allied to T. castaneus, that it may be doubted whether 

 it is more than a Variety. 



PAPYRACEUS. 48. Shell thin and brittle, with five 

 transverse striae, and rows of white dots near 

 the suture which are alternated with red 

 ones ; aperture effuse, and the throat sil- 

 very.

Inhabits the East Indian Seas. Chemnitz. 



By Chemnitz's figures this shell appears to be about ten or 

 eleven lines long, and the breadth rather exceeds the length ; 

 the body-whirl is very large, and the aperture oval and ef- 

 fuse ; it is said to be of an agate-colour, with rows of white 

 dots which are alternated with red ones near the suture, and 

 to be a very scarce species. 



sEMicosTATus. 49. Shell conical, minute, with four 

 or five rounded whirls, of which the body- 

 whirl is minutely striated transversely, and 

 on the upper part longitudinally ribbed.

Inhabits the coasts of Devonshire and Scotland. Montagu. 



Shell about half a line long, and half as broad, white, obtusely 

 pointed, with four or live rounded whirls, which are well 

 defined by the suture ; the ribs on the body-whirl do not ex- 

 tend to the base, where the transverse striae are most con- 

 spicuous. Mr. Montagu says it somewhat resembles P^o- 

 lata pellucida, but the ribs are coarser, the whirls more 

 rounded, and it has not any plait ou the pillar.
