ing from them four confined to land or fresh water, there re- 

 main eighty-seven, of which thirteen alone are peculiar to the 

 eastern coast of South America south of the West Indies, and 

 seventy-four are common Antillean shells. Two appeared to 

 be undescribed, and one, a very young Octopus, was too imma- 

 ture for identification. This would leave eight-ninths of the 

 species in common with the fauna of the Antilles. A large 

 proportion of these extend at least as far southward as Monte- 

 video, and the southern limit of the Antillean fauna may be re- 

 garded as situated in that vicinity. 



Most of Dr. Branner's shells were obtained from the vicinity 

 of Pernambuco, collections were made from the existing coral 

 reefs, the limestone reefs of doubtful age which exist along 

 this coast, and to some extent from the sand beaches behind the 

 reefs. The collection was not large enough to indicate whether 

 the fauna of the stone reefs and that of the coral reefs differ, 

 but in all probability they do not. 



The localities from which mollusks were obtained are as fol- 

 lows : 



Pernambuco and Tacuara near by. 



Maceio ; on granite bowlders, sand beach and reefs, latitude 

 9° 40' S. 



Boa Viagem ; stone reef. 



Cotonello Bay. 



Managuas and Mangosoules on the Rio Parahyba do Norte, 

 Cabedello ; mangrove swamps. 



Mamanguape; stone reef, latitude 6° 58' S. 



Rio Goyanna ; stone reef off the mouth of the river, latitude 

 6°33'S. 



Among the local species Valuta hehrcea and Ttirbinella 

 ovoidea appeared to be common, and Fasciolaria aurantiaca 

 abundant. No peculiarity of texture or aspect which could be 

 regarded as general differentiates the Antillean species of 

 Brazil from the individuals of the same species found in the 

 West Indies, the only approximation to such a feature being the 

 gray color of the specimens of Trivia pedictilus which I have 

 not observed in any of our very numerous series of that species 

 from the West Indies and Florida.
