narrow, pale yellowish line. Side of head and iris silvery-white. 

 Slight dusky tint on opercle behind and above. Vertical fins and 

 pectoral grayish, ventral paler. Length 305 mm. No. 7,572, A. N. 

 S. P., tj^pe of B. diplotaenia Cope. 



Identical with S. tiniucu (Walbaum), differing apparently in the 

 lateral bluish stripe edged with black and then yellowish all along 

 below. Cope says of B. diplotaenia eye 2.5 in postorbital, eye equals 

 interorbital and pectoral equals postorbital, though I find the 

 pectoral about half an eye-diameter longer than postocular.
