peduncle 2f in head ; pectorals about J length of head, their tips reaching 

 vent ; ventrals If in head, reaching about \ distance to vent. Premaxillary 

 groove narrow, usually linear and naked, and not extending quite to the 

 vertical of center of pupil. Color silvery, with bluish reflections, darker 

 above lateral line ; tips of spinous dorsal black ; ventrals dusky ; a black 

 supraorbital spot; caudal dusky; body covered with very fine dark punc- 

 tulations. Length 3 to 6 inches. The specimens here described from 

 Panama. Pacific coast of tropical America; Galapagos Islands; Panama. 

 Specimens very similar have been taken at Key West and Havana, but 

 these may be referable to Eucinostomus harengulus. (Named for Capt.
