This is the largest species of the genus. The concentric strire on 

 the left valve f are comparatively fine, and generally less con- 

 spicuous than as represented in the figures in the " Astrolabe " 



* The following species is omitted : — 

 Thracia novcu-zealandke, Reeve. 



t Mr. Smith says that considerable difference of opinion exists as to 

 which is the posterior end of this shell. I do not understand how this can 

 be for the pallial sinus is well marked. Mr. Smith's drawings show that it 

 is the left valve which is flat. This is true for all the species that I have 

 examined.
