mark, where, in one or two tides, they were converted into the most 

 perfect skeletons by the many small Crustacea which are very nu- 

 merous at that place. 



PACIFIC COAST OP AMERICA. 



From the region included between the Gulf of Georgia and Panama, 

 we have received very large and most valuable collections from Mr. 

 T. G. Cary, of San Francisco ; from Capt. Watkins, of Panama, and 

 Alex. A. R. Agassiz, of the United States Coast Survey. To Mr. Cary 

 the Museum is indebted for a great many thousand fishes, reptiles, 

 mollusks, Crustacea, and echinoderms from San Francisco Bay, which 

 he has collected himself during several successive years. It is, indeed, 

 to his exertions chiefly that our Museum is indebted for the magnifi- 

 cent collection of specimens it now possesses from California. From 

 Capt. Watkins we have received a number of very rare and new spe- 

 cies of fishes, taken in the Bay of Panama. Mr. A. Agassiz has been 

 able to procure a great number of specimens of all classes of animals 

 from the Gulf of Georgia, and along the Pacific coast of Mexico, and 

 has presented the first corals that we have received from the Western 

 Coast of America. He has also been very successful in preserving 

 specimens of medusae in alcohol. 



Mr. Cary and Mr. Agassiz, among theijr other specimens, have sent 

 us several thousand of the viviparous fishes of the Western Coast. In 

 connection with these collections, we take pleasure in acknowledging the 

 liberality of Messrs. Wells, Fargo, & Co., and of the Pacific Mail Com- 

 pany, who have forwarded these large collections to Cambridge free 

 of charge. 



KENTUCKY RIVER. 



Mr. A. Hyatt spent the summer months very successfully on the J 

 Kentucky River, for the purpose of collecting and studying the Unios 

 of that region, several thousand specimens of which, in alcohol, he has 

 presented to the Museum. Mr. Hyatt also devoted much time to : 

 other departments of Zoology, and has presented the valuable results 

 of his labors to the Museum. 



To the large collections made on the Kentucky River he has added 

 a large number of the fishes, Crustacea, and insects from the Mammoth 

 Cave in Kentucky, and also a very large series of fossils from Cincin- 

 nati and its vicinity.
