CILETODONTID^E, OR CHUETO- Scupaug, P. ar gy r<>ps, Cuv. 

 DON FAMILY. This Family comprises spine-rayed fishes 

 which have the body compressed and scaly, and the dor- 

 sal and anal fins scaly. The Chsetodons are so named 

 from their teeth, which resemble bristles collected in rows 

 like those of a brush. Their mouth is small, and colors 

 brilliant. They abound in the hot seas. Eighteen gen- 

 era and one hundred and fifty species are enumerated. 



The Genus Chatodon contains C. rostratus, Bl., of Java, 

 which has the faculty of spirting drops of water so as to 

 hit insects on the plants near by, and bring them down 

 so that it can secure them for food. 



The Genus Ephippus contains those known as Horse- 

 men. They have a dorsal deeply emarginate between 

 the spinous and soft rays ; and the spinous part can be 

 folded into a groove formed by the scales of the back. 



The Banded Ephippus, E. faber, Cuv. & Val., of the 

 Atlantic, is from five to eighteen inches long, brownish, 

 with six broad, vertical dusky-bluish bands. 



The Genus Pimelepterus has the fins much thickened 

 by the scales which cover them. It contains the Razor- 

 Fish, P. Boscii, Cuv. & Val., of the Atlantic, near the 

 Southern coast. It is six inches long. 



The Genus Toxotes contains the Archer, T. jaculator, 

 Cuv., of Java, celebrated for the same faculty which dis- 

 tinguishes C. rostratus, that of spirting drops of water so 

 as to bring down insects from the plants above it r forcing 

 water three or four feet, and rarely missing its aim.
