178 Mr. J. G.Jeffreys on the Marine Testacea 



on my authority iu the ' British MoUusca,' I have taken this species 

 on the west coast of Scotland iu an immature state ; and the Me- 

 diterranean specimens confirm my idea of its distinctness, and identity 

 with Costa's species

 ticum. Ph.). — C. pygmseum, B. 31. (C. exiguum. Ph.). Although 

 there can be no doubt of the identity of these two species, it is rather 

 singular that Philippi does not notice the interstitial punctures, but 

 merely says, " interstitia leviter transversim striata." — C. minimum.
