Two spcciuKMis from Truk, Caroline Islands, Nos. 09059, I2 inches long, and 

 090o2, M. C. Z. 29582, lii inches long. The last has the following measure- 

 ments, dorsal IX, 272; anal 111, 252; scales minute; II lohate teeth in eacli jaw; 

 the ridges of the larval form are indicated on the cheek and on the throat . ( leii- 

 eral color light purplish brown, a broad silvery area as wide as snout extending 

 fi'oni belly to a little above ])ectoral: dorsal, ventral, and anal dusky: pectoral 

 and caudal pale; trace of a yellowish i)and across base of caudal. Number 

 09059 seems to differ from the above only in the fin rays which are: dorsal IX, 

 2(i; anal 111,24. 



Because of the small size of these sjiecimens it is impossible to identify them, 

 with certainty, hut they agree more nearly with Acanthunis nigros (limther 

 especially in the number of teeth and the ilii formulae than with any other 

 described species.
