 Shell about six or seven inches long, and nearly half as broad ; 

 pellucid, thin, brittle, of a pale horn colour, and darker to- 

 wards the summit, which is faintly variegated with purple 

 and bluish green ; it is marked with about eleven longitudi- 

 nal spinous ribs, which occupy about two-thirds of each 

 valve, and the other third is only obliquely wrinkled. 



inflata. 5. Shell sub-triangular-ovate, slightly- 

 keeled longitudinally, with abbreviated ribs 

 on one side, and reticulated wrinkles on the 

 other.

Inhabits the coasts of the Nicobar Islands. Chemnitz. 



Chemnitz has described this species to be four inches and five 

 lines long, and two inches and five lines broad, pellucid, 

 brittle, and of a horn colour ; the longitudinal ribs are ex- 

 tended only three fourths of the way from the apex towards 

 the opposite margin, and not throughout the whole length, 

 as in P. pectinata; the two thirds of the shell which has 

 these ribs is separated by an obsolete longitudinal keel, and 

 the other third of each valve is said to be minutely reti- 

 culated. 



carnea. 6. Shell sub-triangular, pellucid, with 

 eight or ten longitudinal ribs beset sparingly 

 with vaulted spines at the broader end.
