114. (See first Report, pars. 79-83.) Acapulco being notorious for the 

 exotic species quoted in its fauna, it is desirable to examine all authentic 

 collections from that prolific localitj'. The Smithsonian series were ob- 

 tained by Dr. Newberry* (N.), after his Pacific R. R. ^Explorations {vide 

 p. 593) ; by Mr. Belcher {B.) ; and by the Rev. J. Rowell {R.), who obtained 

 them principally from the valves of the large oysters. The private collec- 

 tions of Judge Cooper, Col. Jewett {J.), "ud other American naturalists have 

 also afforded valuable information. The species from these various sources, 

 which were also found by Mr. Xantus, are tabulated with his Cape St. Lucas 

 series, anted, pp. 619-620. The following have not been obtained from the
