sand. 



* The T. alta is lost in this country. There is no figure in Conrad. In genera that are 

 loosely defined, there is a danger of species reappearing under two heads, as in the case of 

 Psammobia decora, Hds., which however was figured. The biangulate character assigned to 

 T. alta makes the IScrobicularia suspected. 



t There is a Tellina Californica, as of Conr., in the Brit. Mus., which is probably identical 

 with one of these published species.
