SILVER CHvETODON. 



Chaetodon Argenteus. C. caada bifida, spinis pinna dorsalis octo, 

 pinnarum ventralium loco spinis duabus. Lin. Syst. Nat. 

 Gmel.p. 1242. Am. Acad. 4. p. 240. 



Silvery Chaetodon, with bind tail, eight spines in the dorsal 

 fin, and two spines in the place of ventral fins. 



This, which appears to be an anomalous species, 

 is said by Linnaeus to differ from the rest of the 

 genus in the defect of the pectoral fins, in place of 

 which are two small spines : the first spines of the 

 dorsal fin are so small as to be scarce perceptible. 

 Native of the Indian seas.
