188 SUPPLEMENT. 
Dr. Meek (Publ. Columbian Mus., Zool. vii. 1907, p. 140) compares this species 
with C. trimaculatum, from which it is said to differ in several features, none of which 
are very marked, 
Cichlosoma motaguense (p. 29). 
Recorded from Belize by Meek (Publ. Columbian Mus., Zool. vii. 1907, p. 151). 
Cichlosoma managuense (p. 29). 
Recorded from Lago de Guila in Nicaragua by Meek (Publ. Columbian Mus., Zool. 
vii. 1907, p. 152). 
HERICHTHYS (p. 30). 
Examination of a large series of examples of Herichthys cyanoguttatus received 
recently shows that the pointed inner teeth are more or less compressed. The genera 
Herichthys and Paraneetroplus may nevertheless be maintained, the former including 
species with slender teeth, those of the outer series in the lower jaw gradually 
decreasing in size and becoming acutely pointed laterally. This genus includes 
H. cyanoguttatus, H. bocourti, and H. geddesi, whilst Garman’s Heros pavonaceus 
probably belongs here also. 
PARANEETROPLUS (p. 31). 
This genus differs from Herichthys in having broader and more strongly compressed 
teeth. The outer series in the lower jaw is transverse, formed of subequal teeth with 
rounded or obtusely pointed apices; it ceases abruptly and does not extend back on 
the sides. Heros sieboldii, Kner & Stdr. (of which Herichthys underwoodi, Regan, is 
a synonym), from Costa Rica and Panama, belongs to this genus. 
NEETROPLUS (p. 31). 
Neetroplus nematopus (p. 31). 
Recorded from Lago de Guila in Nicaragua by Meek (Publ. Columbian Mus., Zool. 
vii, 1907, p. 158). 
SCIANIDE (pp. 31, 32). 
Micropogon undulatus, C. & V. (Jord. & Everm. Bull. U.S. Nat. Mus. xlvii. 1898, 
p. 1461), is a marine species ranging from Cape Cod to Montevideo. It has been 
recorded from Lake Yzabal by Vaillant and Bocourt (Miss. Sci. Mex., Poiss. 1874). 
GERRES (p. 37). 
The characters of G. peruvianus and G. olithostomus have unfortunately been 
transposed in the synopsis of the species (p. 38). It is G. peruvianus which has the 
mouth smaller and the scales of the thoracic region larger.
