long as width of eye. Probably A. etcnodon, Cuv. & Val., should 

 stand for this fish, as such a marked increase in the number of 

 teeth and scales, if fixed characters, would give it specific rank. 

 Two specimens were taken. Length 1.50-6 inches. Guam, July, 

 I goo. Hab. Polynesia, Marianas.
