Inhabits the Southern coasts of Europe. Linnaus. Jamaica.

 Humphreys. 



The base is two or three inches long, and three-fourths as 

 broad, and the height is less than half the breadth ; the shell 

 is white, rather transparent, with the summit more or less 

 bare, and the sides coated with transverse zic-zac rows of 

 dark purplish brown scales ; the outside colouring is seen 

 on the inside through a thin coat of pearl, and the muscular 

 impression is generally of a rich reddish brown. Martini's 

 figures 73 and 74 are copied from Lister, t. 733. f. 12, and 

 this again from Columna ; on which account I do not think 

 them worth attending to. 



CHLOROSTiCTA. 28. Shell ovate, depressed, with 

 eleven broad and intermediate narrower ribs ; 

 margin angulated.

Inhabits the coasts of Jamaica. Martini. 



The length at the base rather exceeds an inch and a half, and 

 the breadth at the broader end is almost equal ; the colour 

 is brownish yellow, with broad chestnut rays and green scat- 

 tered dots ; the inside has longitudinal grooves correspond- 

 ing with the ribs on the outside ; the muscular impression 

 and the inner margin are chestnut-brown, and in the figure 

 there appears a yellowish belt between them. From his 

 appendix, p. 844, it is plain that Favanne considered this 

 shell to be only a Variety of P. granatina. 



TIGRINA. 29. Shell oval-oblong-, with seven de- 

 pressed ribs and intermediate longitudinal 

 striae ; margin sub-octangular and crenated.
