similar dentition, and form a series from the strictly conical teeth of 
most of the Cichlasoma nearly to the strictly compressed incisor teeth 
of Neetroplus. The fact that the dentition of the species listed under 
these genera vary so greatly, apparently with age, renders this character 
of little generic or specific value. Vertebre 16+16=32. 
Cichlasoma friedrichsthali (Heckel). 
Heros friedrichsthali Heckel, Flusfische Brazil, 1840, 381 (Rio San 
Juan, Nicaragua). 
The specimens listed below have 6 with 7 anal spines, 2 with 8, 
. and 6 with 9. The smaller specimens have from 7 to 9 dark lateral 
bars with a faint broken lateral band; the larger ones have a more 
prominent lateral band with the bars faint or wanting. Usually a 
black spot on suboperculum; soft dorsal, anal and caudal fins with dark 
dots.

Cichlasoma citrinellum (Ginther). 
Heros citrinellum Gunther, Proc. Zodl. Soc. Lond., 1864, 153 (Lake 
Nicaragua). 
Cichlasoma cttrinellum Regan, Biol. Cent. Amer., 1908, 187 (Juan 
Vifias, Costa Rica). 
I did not obtain any specimens of this species in Costa Rica. It is 
very abundant in the lakes Nicaragua and Managua and in the smaller 
neighboring lakes. It is mteresting, though rather unexpected, to find 
this species at an altitude of over 3,000 feet in Costa Rica and not in 
the streams of the lower lands. No doubt it occurs there but is prob- 
ably very scarce.

I did not obtain any specimens of this species.
