precede it. The pectorals are yellow. An infraorbital black 

 spot is present. 



This species of Acara was first indicated under the name of 

 Chromis taenia by Mr. E, T. Bennett, who described it from 

 specimens in a small collection formed during a voyage of 

 H. M. S. Chanticleer, This notice is in Latin, and is confined to 

 a description of the color and of the radial formula. He gives 

 as its habitat the island of Trinidad. Subsequently Dr. 

 David H. Storer gave a translation of this description in an 

 appendix to his " Synopsis of the Fishes of North America," 

 originally published by the American Academy of Arts and 

 Sciences, in the third volume of their new series of " Me- 

 moirs." 



This fish is in that memoir said to be found in the Carib- 

 bean sea on the authority of Mr. Bennett, although that 

 naturalist had simply stated that it was found, in Trinidad 

 (" apud Trinidad "). The learned ichthyologist of Boston, who 

 appears to have been unacquainted with Dr. Heckel's memoir 

 on these and the allied genera of fishes, was probably misled 

 by the knowledge that some of the species of the genus 

 Chromis found in Europe were marine, and as Mr. Bennett 

 had not stated that it was from the fresh waters of Trinidad^ 

 rather hastily assumed that it also was marine, and would conse- 

 quently be found in the whole of the Caribbean sea, in accord- 

 ance with the law which appears to govern the geographi- 

 cal distribution of the marine fishes, as well as the other "West 

 Indian marine animals. 



Genus. 

 Cbenicichla, Heckel. 



Body oblong, covered by small scales ; dorsal and abdominal 

 outlines nearly rectilinear and parallel with each other. 

 Head with the lateral aspect elongately triangular.
