CHROMIDES AND PHARYNGOGNATHI 
UBORDER Chromides.—The suborder Chromties con- 
taims somy-rived fishes smmlar to the perch-Itke 
ae ™ forms mm most regards. but stmkmely disumgushed 
by the complete ution of the lower pharyngeal bones, as m the 
Eclconett and FPharvngegnaitt, and still more remarkably by 
ehe —— of but one nasal opening on each side. Im all the 
perch-ltke fishes and m nearly all others there are two nasal 
openings or nostrils on each side. these two entermg mto the 
sare masal sac. In all the Curcmices the lateral Ime is meom- 
plete or mterrupted, and the scales are usually large and ctenoid. 
The Cichlide.—The suborder Chromides includes two famt- 
Hes. Crotlige. and Pomacentride. The Ctichltde are fresh-water 
tshes of the tropics. characterized by the presence of three to 
tem sfimes in the anal fm. Im size. color, appearance. habits, 
erates ae ad value they Dear a striking resemblance to the fresh- 
water sumtshes. or Ceouiraurchiie. of the eastern Untted States. 
This resemrcolance is ome of analogy only, for m structure the 
Cite have no more im common with the Centrurchtde than 
with other famrtes of perch or bass. The mumerous species 
of Cronrcg are confined to tropical America and to correspond- 
ing districts m Africa and western Asta. Tulupta mtlctica 
abounds in the Nie. Tilapia galilga is found in the river 
oe and the Lake of Galil This species is supposed to 
cm. part of the great draught a fishes recorded im the Gospels, 
a black spot on the side is held to commemorate the touch 
of Simon Peter. Numerous other species of Cichlid, lange and 
small. abound m central Africa, even im the salt ditches of the 
Sahara.
