 Falkland Islands. Favanne. 



The length of the base sometimes exceeds two inches and a 

 half, and it is then nearly two inches and a quarter broad ; 

 Favanne has described the ribs to be of a dark brown, with 

 their interstices of a bluish slate-colour ; but it is said that 

 the shell varies much, both in form and colour, and that it 

 is sometimes of a dark mottled brown with white bands, 

 which answers to Martini's figure ; the inside is channelled 

 and white, and the muscular impression silvery. In Fa- 

 vanne's appendix. Martini's iig. 66, is referred to, and they 

 have both quoted D'Avila, t. 3. f. D, which is strongly 

 marked with imbricated concentric wrinkles ; Born has 

 strangely cited the same figure of D'Avila's for his P.plicata^ 

 which it is very unlike. It is said by Favanne, that those 

 shells of this species which are of a yellowish brown colour 

 will, by being kept a proper time under hot cinders, become 

 of the colour of gold, and equally brilliant. 



CRENATA. 33. Shell ovate, rather depressed, slight- 

 ly ribbed, and unequally striated longitudi- 

 nally; margin crenated.

The length of the base is from an inch to an inch and a half, 

 and the breadth is about five-sixths of the length ; the co- 

 lour is pale yellowish brown with grey between the ribs, and 

 marked with fine longitudinal striae and grey transverse bands. 

 Martini's fig. 05 has the margin angulated, as well as cre- 

 nated, but Favanne considered this to be distinct from fig. 

 64, and to be a Variety of Le Grand Soldi, which is P^ 

 margaritacea.
