panied by smaller ones), canine-like ; anterior smallest, directed 

 downwards, posterior ones downwards and backwards; anterior 

 palatines larger than premaxillary teeth, and more compressed 

 and widelj^-set ; posterior ones small and closely-set ; order of teeth 

 on lower jaw reversed, but similar to those on the palatines, and 

 smaller, about 10 in series ; large tooth near tip of lower jaw present. 



Origin of dorsal over or slightly in advance of ventrals, well 

 behind point of pectorals ; distance between dorsal fins 5^ in 

 length of body ; distance from tip of snout to spinous dorsal 2tV 

 in body ; scales moderate, somewhat larger behind soft dorsal and 

 anal ; cheeks and opercles scaly ; small imbedded scales on upper 

 parts of head. 



Color olivaceous, silvery below ; young with dusky blotches 

 across the back and along the lateral line. 



This description is made from eight specimens collected by 

 Professor Jordan at Wood's Holl, Mass., which vary in length 

 from six and one-fourth to eight and one-half inches. The species 

 does not appear to reach a length of much more than a foot. 

 This species shows several points of similarity to Sphyrsena 

 splujrsena. It is, however, unlikely that the two are specifically 

 •identical. 



Below is given a table of four specimens. The proportions are 

 given in hundredths of length from tip of snout to end of last 

 vertebra.
