868 TURBO. 



By Chemnitz's figures this shell appears to be about eight lines 

 in diameter, and to belong to the same family as Helix 

 Ocuhis Capri; the upper surface is marked with longitu- 

 dinal zic-zac stripes, and the base and umbilicus are entirely 

 white.

 Inhabits Jamaica. Linncciis. 



Shell three or four inches long, and not quite one-fourth as 

 broad, of a pale brownish white colour, clouded and dotted 

 with reddish brown ; it has twelve or thirteen transversely 

 striated flattish whirls, and some of the larger striae are 

 slightly granulated ; the whirls are slightly gibbous at their 

 lower, and contracted at their upper extremities, which gives 

 them some appearance of being imbricated downwards. 



REPLiCATus. 128. Shell turreted, smooth, with the 

 whirls imbricated upwards.

 Inhabits the coasts of Tranquebar. Martini. 



Linnaeus has so described this shell, but the whirls in Argen- 

 ville's figure, which he has quoted, have not, any more than 

 Martini's, the least appearance of being imbricated upwards; 

 and it appears to me to be altogether rather a doubtful spe- 

 cies : in the Mus. Lud. Ulrica it is described, " Testa cor- 

 nea pallide umbrosa, laevis non glabra. Anfractus sursum 

 imbricati, margine angusto, apertura ovata integra." Mar- 

 tini's figure is nearly two inches and tlwee-quarters long, and 

 one third as broad, of a pale brownish flesh-colour, with ten 

 or twelve whirls, which have the appearance of being keeled 

 in the middle, and slightly striated transversely.
