REPORT 1863. 



The following fossils were also col- 

 lected by Col. Jewett : 

 Purpura crispata I San Francisco, 160 ft. 

 ostrina ( above the Bay. 



Tellina congesta, Conr. Monterey. 

 Scalaria : can scarcely be distinguished 



from planicosttita, Kien., in Brit. Mus. 



(?=Gr(Klandica) : Panama, 



The collections of Major Rich, having been tabulated by Dr. Gould simply 

 as from Upper or Lower California, I had expected to find of but little geo- 

 graphical value. They proved, however, to be of peculiar interest. Major 

 Rich had been one of the naturalists in the U. S. Expl. Exp., and his warlike 

 occupations did not prevent his remaining long enough at particular stations 

 to pay close attention to the Molluscs. His forte lay in procuring shells in 

 the best possible condition ; and a study of them was very serviceable in 

 explaining the dead shore-shells usually obtained from other sources. For- 

 tunately, he was quite aware of the importance of geographical accuracy, and 

 arranged those obtained at different places in separate drawers. The " Upper 

 Californian " collections were made at Monterey, San Francisco, San Diego, 

 and San Pedro ; the " Lower Californian," in the Gulf, principally at La 

 Paz, partly at San Jose and Mazatlan. At the latter place he met M. 

 Reigen, who had filled his house with decomposing molluscs to such an ex- 

 tent as to induce the neighbours to have recourse to the police. From him he 

 obtained many species not in the Brit. Mus. Cat., and probably sent to Europe 

 in the Havre collection. Major Rich's beautiful series may be consulted at 

 his residence, opposite the British Legation, Washington, D. C. ; and are 

 designed ultimately for one of the public museums in the neighbourhood. 

 The following is a list of the species :
