LIFE COLORS OF PffiCILIA LIMANTOURI, AND DESCRIPTION OF A NEW HEROS 



FROM MEXICO. 



BY HENKY W. FOWLER. 



The Academy has received a small collection of fishes from Tamaiili- 

 pas, Mexico. They were secured January 16 by Mr. S. N. Rhoads, 

 while on his recent visit to Mexico, in the warm waters of the Victoria 

 river near Victoria. This is a small stream tributary of the Rio Soto 

 la Marina, at the foothills of the Sierra Madre Mountains in western 

 Tamaulipas. 



The material is in excellent condition, so that it is possible to give 

 the hfe colors of the Poecilia, which were unknown.
