DR. GUNTHER ON THE FISHES OF CENTRAL AMERICA. 385 
gentleman from the Pacific Coast of Central America was published in the Society’s 
‘ Proceedings’ for 1861 (Nov. 26); it contained fourteen species, ten of which were new. 
In the following year the 4th volume of the ‘Catalogue of Fishes’ was published, 
containing the descriptions of those species of Pharyngognaths and Anacanthines which 
had arrived from our travellers, who were then engaged in collecting.

“Fishes from the western coast of Central America, presented to the Smithsonian 
Institution by Capt. J. M. Dow.” He distinguished in it the following twenty-five 
species, of which I consider eighteen to have been new to science (Proc. Ac. Nat. Se.
