 marle Is., Chatham Is., and Hood's Is.§§ 



2f}. Scarcely any mention is made of W. American shells by Linnaeus, 

 Chemnitz, and the older conchologists generally. A very few handsome 

 species from the Panama province, such as Oliva porphyria, &c., had found 

 their way into European collections and books, perhaps tlirough the pearl 

 oyster trade ; or even, it may be, introduced indirectly through East Indian 

 commerce. But our first direct acquaintance with the shells of the Panama 



* The shells of this place rank somewhat better with Lower than with Upper California, 

 with which it is locally and politically connected. It was the first settlement on the coast, 

 having been founded by the Jesuits in 17C9. There is another San Diego in the Gulf of 

 Tehuantepec. 



t Not to be confounded with Cape Palmar, on the equator, in long. 80° ; nor with Cape 

 Falmas on the Guinea coast, where are islands (St. Thomas and St. Vincent) liable to be 

 associated with the Antilles. 



X There is also a San Jose between the two capes at the end of the promontory, and 

 another in the harbour of San Francisco. An island of the same name is in the Bay of 

 Panama. 



§ Besides this station and the Straits of De Fuca, there is a San Juan on the opposite shore 

 near Guaymas ; another near San Bias; a Point on the coast near Lake Nicaragua ; and a little 

 island between Is. Catalina and San Diego. 



II There is another San Miguel near the Bay of Fonseca, in long. 8S'5°j also a port in the 

 Bay of Panama, lat. iS° 10' ; and an island outside Sta Barbara. 



^ Not to be confounded with Lobos Is., Peru. 



** Another Gulf of Dulce opens out of the Bay of Honduras. 



■ff This is quoted by Prof. Adams as a corruption of Taboga. It is, however, marked in 

 the charts as a very small island, N.W. of San Jose and one-third of the distance between 

 that and Taboga. A river Chiriqui is also quoted as in the Bay of Panama. Perhaps it is 

 near the town of the same name in Veragua. There is another Chiriqui between Greytown 

 and Chagres. 



tJ There is a Bay of San Francisco in Lower California on the Pacific side, in lat. 30°, and 

 another near San Miguel within the Gulf. Also a Bar of the same name in the Gulf of Tehu- 

 antepec. 



§§ Another Hood's Is. is in lat. 21°S., long. 135° W. Which of these is the "Lord Hood's 

 Is." often quoted in Mr. Cuming's Coll., is not known. It is possible that some species be- 

 longing to the Galapagos fauna have been passed over, from their being assigned to the Poly- 

 nesian station.
