Guatemala. 



Head 4; depth 4; D. 12 or 13; A. 14 to 16; scales 12-32 to 35. Body moder- 

 ately elongate; head thick and broad; interorbital area broad, slightly convex, 

 its width being a little less than half its length; snout broad, obtuse, lower jaw 

 slightly projecting beyond the upper; mandible longer than eye; diameter of eye 

 about equaling length of snout, 4 in head; origin of dorsal fin midway be- 

 tween tip of caudal and posterior margin of orbit, slightly in advance of anal; 

 dorsal fin of male higher than that of female; basal half of caudal fin scaly. 



Color brown above and on sides; pale below; females with a very indistinct 

 dark band along the side; fins plain; anal with a light margin. (Giinther.) 

 Length about 3^ inches. 



Two years ago I suggested that this species and also Fundulus labial-is 

 Gunther, probably belonged to Zoogoneticus . Mr. C. Tate Regan* has since 

 reexamined the types and finds that both species belong to Fundulus.

Guatemala and southern Mexico. 



Head 4; depth 4^; D. 12; A. 13; scales 12-34. Body little elongate; head 

 broad, interorbital area slightly convex, its width 2 in head; snout broad, 

 obtuse, much depressed, the lower jaw scarcely projecting beyond the upper; 

 mandible longer than eye; upper lip of moderate breadth; eye small, 4^ in 

 head; origin of dorsal slightly nearer extremity of caudal than orbit, over the 

 i gth scale in the lateral series ; dorsal fin slightly in advance of anal ; pectoral fins 

 not reaching base of ventrals, shorter than head (without snout) ; caudal fin 

 subtruncate, scaly on its basal half. 



Color brownish olive, paler below; each scale, especially those on the tail, with 

 a vertical dark purplish violet spot on the center; dorsal with 3 or 4 series of 

 blackish dots, anal with a whitish margin. Length about 3^ inches. 



Through the courtesy of Dr. B. W. Evermann, of the Bureau of Fisheries, I 

 have been permitted to examine a number of specimens of this species, which 

 were collected by Dr. Gustav Eisen in July, 1902, in Lake Atitlan, Guatemala, 

 at an altitude of about 4,500 feet. These specimens agree very well with the 

 description given by Dr. Gunther, except in the absence of spots on the dorsal 

 fin.
