the curiosity to know more and to know more accurately. 

 An expedition of circumnavigation, with the specific objectof 

 investigating the distribution of the testaceous Mollusks,

 manner which would justly inspire confidence. 



Index of Places in the Pacific, which are mentioned in the Catalogue of Panama 



Shells. 



Arapulco. A town and harbor, in Mexico ; it is the principal and beat port of 

 Mexico on the Pacific; lat. 16 55' N.; Ions*. 100 54' W. 



Annan. An island in Polynesia. Probably Anna or Aana, or Chain Island ;

Arica. In Peru. 



Atacarnas. A seaport in Equador, on the Pacific. 



California. The boundary between Upper and Lower California is near lat 

 S3 N. The waters of Upper California, therefore, belong wholly to the tempe- 

 rate Fauna, and those of Lower California almost wholly to the tropical Fauna. 

 The Fauna of the Gulf of California is tropical, at least as far as Guayiuas. The 

 importance in zoolo y of distinguishing between Upper and Lower California, in 

 statements of habitat, is therefore obvious. New Albion was a name given by 

 Sir Francis Drake, to an extent of coast which includes upper California and Ore- 

 gon, and is ofien used more indefinitely.
