Fig. 1. — Myctophum giihfTti Kverniaiiii A- Seale. new species. Type. 



posterolateral 1, very near lateral line and verticallj' on a line between interspace of anal photophores and 

 base of adipose dorsal; mediolaterals 3; forming a very obtuse triangle, the upper one very near lateral line, 

 the lower one midway between lateral line and origin of anal fin, a little too far front to form a true oblique 

 line from posterior inediolateral to posterior ventral photophore, the anterior one on a horizontal line with 

 the last and vertically over the posterior margin of second ventral; anterolateral 1, just above middli> of 

 pectoral fin and on first scale below lateral line. 



Origin of doreal fin midway between tip of snout and posterior anal photophore, the longest ray equal 

 in length to distance from pupil to posterior mai'gin of opercle; origin of adipose dorsal midway between 

 posterior a.xil of dorsal and base of caudal; origin of anal midway between anterior thoracic photophore and 

 lower caudal photophore, directly below axil of dorsal, its longest ray 1.5 in head; ventrals 2.5 in head, their 

 origin below seventh scale of lateral line; pectoral long, 1.4 in head, tip extending to anterior mediolateral 

 photophore; caudal forked, about 1.75 in head (mutilated).
