D. III, 9 to III, 11, first branched ray 1 2/5 to 1 3/5 in head; 
adipose fin 3 2/5 to 3 3/4; A* III, 14 to III, 16, first branched ray about 
2?; caudall well forked; least depth of caudal peduncle 3 1/4 to 3 1/2; 
pectoral 1 l/4 to 1 2/5; ventral 2 1/8 to 2 1/4. 
Brownish, upper surfaces where scales have fallen darker. Sides of 
head and body silvery, with bright iridescent reflections, especially on 
scales. Snout pale or whitish. Fins all pale brown. 
Indian and Pacific Oceans. A species greatly like Myctophum spinosum 
in some respects, especially its well scaled fins. The front of the dorsal 
and anal, as well as the caudal, largely covered with large scales, a fact 
not shown in Gilbert’s figure or mentioned in his description. This is 
doubtless due to the condition of his specimens, as in most preserved 
materials they have disappeared. He states of the scales "their edge® 
strangely toothed, the teeth entirely absent or obsolescent on the scales 
of the lateral line". This must, however, be a variable character, as I 
find the scales of the lateral line with 6 to 10 strong marginal denticles. 
Other specimens are entirely with smooth edged scales.
