The base is about two inches and a half long, and two inches 

 broad, and the height of the shell is sometimes nearly equal 

 to the breadth ; in the natural state it is of a dull ash-colour, 

 but when polished it becomes of a chestnut-brown with the 

 ribs nearly white, and in this state it has been figured by 

 Martini ; the inside is white and silvery, and the muscular 

 impression richly bronzed. It is perhaps impossible to place 

 it beyond a doubt what the P. fusca of Linnaeus is, for he 

 has given only a short description, without any reference to a 

 figure. Born and Shaw have considered it to be the present 

 shell, although its margm is distinctly crenated, whereas in 

 the Linnaean species it is said to be very entire ; but in other 

 respects it answers the description, and Martini, notwith- 

 standing the crenatures, has described it * limbo integro.' 



AREOLATA. 71. Shell pyramidal, depressed, with 

 remote decussated striae ; base round, and 

 the margin nearly entire.

Favanne considered this to be a Variety of the preceding spe- 

 cies, from which it dift'ers in having the base rounder, the 

 margin less distinctly crenated, and the height not much 

 more than half the diameter ; it has about twenty-one longi- 

 tudinal striae, and these are crossed by others transversely, so 

 as to form quadrangular departments; the colour is yellowish 

 red, with a purple summit, and the inside white and pearly, 

 except the muscular impression, which is richly bronzed. 



FLAMMEA. 72. Shell convex, with fine transverse 

 elevated striae, and waved longitudinal stripes; 

 summit nearly central, and the base ovate. 

 Patella flammea. Gmelin, p. 3716.
