Head 5A ; depth 5i D. IV-I, 6 to 8 ; A. I, 20 to 21 ; scales 41-7. The 

 snout is short, not longer than the diameter of eye, and the cleft of the 

 mouth does not extend backward to below the anterior margin of the eye. 

 The anterior dorsal is composed of short, feeble spines, and its origin is 

 opposite to the fourth or fifth anal ray. The pectoral fin is much longer 

 than the head. The silvery streak occupies the adjoining halves of the 

 third and fourth series of scales. Panama. (Gunther); not seen by us.
