Evermann and Goldsborough — Fishes from the Canal Zone, b 



freshwater pond at side of railroad at Gatnn, July 15. Nine ft-male speci- 

 mens \}4 to 2% inches long and one male 13^8 inches long from reservoir 

 at New Porto Bello, February 10, 1909. ]Mr. Jennings says this is the most 

 abundant and characteristic species, ])ut not very efficient larvte destroyers. 

 It appears to be chiefly a bottom feeder. 



Poecilia sphenops Cuvier and Valencienne~. 

 Eighteen specimens l}4 to 2 inches long from Folks Kiver Swamp, Cris- 

 tobal, August A. These show the many variations of this species indi- 

 cated l)y IJegan in BiologiaCentrali Americana. Onesjiecimen \% inches 

 long from reservoir at New Porto Bello, February 10, 1909. Dorsal 9; 

 anal ii, S; scales 2G. Teeth conical or pointed, some of them slightly 

 truncate, and one or two tricuspid. One female specimen 2% inches 

 long from Ancon. This flsh was kept in a tank for o months and pre- 

 served June IS. Six females and one male, % to 1% inches long; no 

 definite locality given. These each show a distinct black spot at anterior 

 base of dorsal tin, covering ?> or 4 rays. The modified anal tin is evident 

 in all, even in the very small one. In the largest example the anal is 

 entirely in advance of dorsal tin and in the others it is variously .so, its 

 origin grading back to directly under origin of dorsal. The origin of the 

 dorsal is uniformly ecpially distant from tip of snout and middle of caudal 

 tin. Seven specimens % to lyV inclies long froniGatun, August 15. These 

 all show 7 or 8 distinct vertical bars on body and 5 of the smaller ones show
