207- Pecten Zclandia. Gray, n. s. 

 Inhab. New Zealand. 



Shell with numerous (about 40) close unequal sharp-edged 

 squamose ribs; purplish ; the ears unequal, with radiate scaly ribs.

App. 

 I nhab. East Coast. Yate. Bay of Islands. Dieffenbach. 



Shell inequivalve, with 16-18 radiating ribs, purplish white ; 

 right valve convex, ribs smooth, the larger one depressed with one 

 or two interrupted longitudinal grooves ; left valve rather concave, 

 smoothish, purple brown, and purple near the umbo ; the ribs dis- 

 tant, narrow. 



"Taken with a landing-net from the bottom of the bays. The 

 flavour is very excellent, and the oculiform tentacles are ex- 

 tremely like eyes. 



" It is impossible to get the scallops perfect ; the edges are so 

 thin, that they generally break." Bidwell. 



209. Lima linguatula. Lam. vi. 157. Quoy et Gaim. 

 Voy. Astrol. iii. 453, t. 76, f. 11, 12.

Island. Dr. Dieffenbach. B. M. 

 A solid plicated species ; not in sufficiently good state to describe.

A small species, much like (). edulis, scarcely to be distin-

 shores everywhere from East Cape northward. "The one like 

 0. Edulis are better flavoured than the cock-combs." Dr. Sinclair. 



Fam. ANOMIADJB.
