ART. 13. — S. TANAKA : 



Color in formalin jet black ; all tlie fins black. 



The species is very closely allied to Scopelus elongaiiis of 

 Kaffaele and Notoseopelus quercinus of Goode and Bean, but 

 differs from both these species in having longer snout, sliglitly 

 slenderer body, a little more numerous scales and in having 

 somewhat differently located j^hotopliores. Moreover, it has a 

 range of distribution different from that of the otber two species, 

 of which Scopelus elongatus was taken in Naples and Notoseopelus 

 que7'cimcs off Newfoundland. Bo that, the specimens before me 

 I will consider to represent a new subspecies of Macrostoyna 

 qnercinum (Goode and Bean) Jordan and Evermann. 



The type is the only specimen known. It was in all 

 probability obtained off Misaki, Province of Sagami and is 

 contained in Mr. Owston's collection.
