FRDM 



THE WEST COAST OF NORTH AMEltlCA, 

 FIRST COLLECTED BY Cou E. JEWETT. 



BY 



PHILIP p. CARPENTER, B.A., Pii.D. 



An account of Col. Jewett's shells will be found in the British 

 Association Reports for 1856 (pp. 2:-26-231) and 18G3 (pp. 53t- 

 539). The exact localities are often uncertain; but many of 

 them have been fixed by subsequent explorers. Being generally 

 worn beach-specimens, the diagnoses have been written (vvhere- 

 ever practicable) from perfect sliells, and especially from the 

 beautiful series dredged by Dr. J. G. Coo])er, in the Californian 

 State Survey. The types belong to Mrs. Boyce, of Utica,N. Y., 

 and are at present in my keeping. The numbers, in the species 

 from the temperate fauna, refer to the table in the British Asso- 

 ciation Report for 18G3, j)p. 636-664.
