128 Fretp Museum or NaturaAL History— Zo6é.Locy, Vor. X. 
Soft dorsal and caudal fins with white spots, these sometimes form- 
ing bars. In 1907* I suggested that this species was probably the 
male of Cichlasoma longimanus (Ginther). Since I secured only the 
one form in Costa Rica and find both sexes represented, it is evident 
that the two species.are not the same. 
La Victoria (4), 140 to 205 mm.; Zent, April 12 (20), 77 to 200 mm. 
Zent, April 15 (8), 68 to 98 mm. 
Cichlasoma spilotum Meek. 
Cichlasoma spilotum Meek, Pub. Field Mus., Zodl. Ser., x, 1912, 73 
(La Victoria, Costa Rica). hs 
This species is known only from material listed below. It is easily 
distinguished from the other Costa Rica Cichlasoma by the decurved 
profile, small subinferior mouth, and by the prominent black spot on 
middle of the side below the lateral line. Vertebre 15+17=32. 
La Victoria (11), 95 to 190 mm. 
Neetroplus fluviatilis Meek. 
Neetroplus fluviatilis Meek, Pub. Field Mus., Zodl. Ser., x, 1912, 74 
(Costa Rica River near Guapilis). 
This species resembles in form Neetroplus nematopus Ginther, from 
Lake Nicaragua. It differs from that species in a more convex inter- 
orbital, a more decurved profile, a more slender body, and in having 6 
or 7 faint though well defined dark bars on the sides. The specimens 
of Neetroplus nematopus in this museum from Nicaragua are uniform 
brownish with a faint dark bar downward and backward from the 
9’’ and 10” dorsal spines; a nuchal crest is also developed on some of 
these specimens 85 mm. in length, and is very prominent on a specimen 
135 mm. On the two specimens of N. fluviatilis there is no nuchal 
crest. 
Costa Rica River (2), 110 to 123 mm. 
Herotilapia multispinosa Ginther. 
Herotilapia multispinosa Gunther, Fishes Cent. Amer., 1869, 453, 
pl. rxxrv, fig. 2 (Lake Managua). 
In general form and appearance this species resembles Cichlasoma 
spilurum, from which it is easily distinguished by its tricuspid incisor- 
like teeth. . Vertebra 13+15 = 28. 
Zent, April 12 (2), 77 to 135 mm.; Zent, April 14 (1), 80 mm.
