vcntrals, which in turn reach base of anal; least depth of caudal 

 peduncle .5 cm.; length of caudal |)eduncle from base of anal to median 

 base of caudal .8 cm.; se\en to eight bars, more distinct and slender 

 in younger exaiui)!es; a median silvery bluish to dark lateral line or 

 narrow band along sides from head to base of caudal; this lateral 

 line very tine in young specimens and never more than the breadth 

 of an orbital in older examples; all specimens with a very minute 

 dark spot at end of lateral line on base of caudal, not more than one- 

 third the size of the eye: the fins colorless as a rule, Init some with a 

 dusky tinge. 



I cannot distinguish these specimens from those coming from the

 Jasciatuni.
