longitudinali. Linn. Gmel. 3217- 

 Shell oblong and white, with a longitudinal brown granulated suture. 

 Pall. Nov. Act. Petrop. 2. p. 240. t. 6. f. 26. A. D. 



This shell, according to Pallas, inhabits the Belgic 

 shores, and penetrates timber. It is more like a por- 

 tion of a Teredo than a Pholas. 



Gmelin's Ph. Campechensis, p. 3215. n. 8. is too ob- 

 scure to be admitted as a species. He refers to Lister, 

 t. 432. for his authority, but the figure is not sufficiently 

 distinct from Ph. Candida, to be considered as specific.
