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

 vent; ventrals If in head, reaching about i, 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 refltctions, darker 

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

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

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

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

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