﻿ElGENMANN : FlSHES OF WESTERN COLOMBIA 



5 



Of the genus Epinephelus. of Bloch, there is also a species ; it repre- 

 sents the subfamily of Serraninae. 



Both the above species are well known. The Centropomus is the true 

 Centropomus undecimalis of Cuvier. 



Of Lutjanus. the typical genus of a peculiar subfamily, Lutjaninae, there 

 is also a species. 



The family of Prist* pomatoids and subfamily of Pristipomatinae is rep- 

 resented by a single species of the genus Haemulon of Cuvier. 



The family of Chromoids or Ctenolabroids is represented by four species, 

 which belong to the genera Cichlasoma of Swainson, Geophagus of Heckel, 

 and Heros of Heckel. All of these belong to one family, for which the 

 name of Chrominae is acceptable. 



The suborder of Physostomi is represented by the families of Characin- 

 oids and Erythrinoids. There are species of the following subfamilies and 

 genera : 



Of the family of Characins ; 

 Subfamily of Pacuinae : 

 Genus Pacu. of Spix ; 

 Subfamily of Leporininae ; , 



Genus Leporinus, of Spix ; 

 Subfamily of Tetragonopterinae ; 



Genus Astyanax, of Baird and Girard, or Poecilurichthys of Gill. 

 Subfamily of Xiphostominae ; 



Genus Ctenolucinus of Gill ; 

 Subfamily of Hydrocyoninae ; 

 Genus Cynopotamus of Valenciennes. 

 Of the family of Erythrinoids there is one representative. 

 Subfamily Erythrininae ; 



Genus Macrodon of Miiller and Troschel. 

 There is also a fine new species of the family of Gymnotoids. 

 Subfamily Carapinae ; 



Genus Sternopygus of Miiller and Troschel. 



Of the subclass of Elasmobranchii and order of Plagiostomes there is 

 also a single species. 



Family Trygonoidae ; 

 Subfamily Trygoninae, 



Genus Trygon of Adanson. 



I have given no specific names to any of the above species, although 

 several are new, as it is uncertain when I will be able to describe them, 

 and it would also be injurious to the progress of science to add to the 

 synonymy by the publication of names of species which may be, before 

 they can be described under those names, made known under other 

 names. 



Very truly yours, 



THEO. GILL. 



ARTHUR SCHOTT, Esq.
