AcRONURID2E. 
Acanthurus, Bl. Found in all the tropical seas with the exception of 
the eastern portion of the Pacific, where they are at least very thinly 
represented ; they appear to haunt coral reefs and feed upon sea-weed. 
The genus Acronurus is only the young stage of Acanthurus^ which 
differs strikingly in appearance from the adult ; but it is as yet impos- 
sible to refer the different forms which have been distinguished under 
the names of Acron. orbicularis, argenteus, &c., to the species of Acaw- 
ihurus, to which they properly belong. Gunther, J. Mus. Godeffr. ix. 
p. 108. 
Acanthurus matoides, 0. V. It is now extremely doubtful whether 
A. matoides, Klunz., from the Red Sea, is identical with the species so 
named hitherto by Gunther, which he redescribes and figures under the 
name of A. hlochii, G. V., the dorsal fin being lower in proportion to the 
height of the body in the latter than in the former ; /. c. p. 109,
