D« III, 8, I or III, 9, I, first branched ray 1 1/5 to 1 l/2 in 
total head length; adipose fin 3 1/8 to 3 4/5; A. Ill, 16, I to III, 19, 
I, first branched ray 1 4/5 to 2; caudal 1 1/3?, well emarginate; 
least depth of caudal peduncle 3 1/2 to 3 7/8; pectoral 1 to 1 1/6; 
ventral 2 to 2 1/3. 
Brownish to dusky where denuded of scales. Body about fin bases 
deep brown to blackish. Sides of head and adherent scales silvery, with 
iridescent reflections. Fins all pale brown to whitish. Iris silvery 
white, gray in preserved specimens. 
Atlantic, Indian and Pacific Oceans. Compared with Brauer*s figure 
90 most of my specimens show the suprapectoral photophore, the second or 
median supraanal and first or lower posterolateral at the same level. 
Brauer shows the first 2 anals and first posterolateral level. 
Although Parr gives "East Indian waters" in his distribution for 
Myotophum benolsti (Cocco), evidently from Weber and Beaufort's 1913 
account, their material is clearly Myctophum reinhardti (Lutken), 
with which they identify it. This is evident from Parr's'key* in which 
the chief character of distinction is given as "Last Pro. (precaudal) 
about midway between lateral line and ventral outline of tail or lower" 
in Myctophum benoisti . Weber and Beaufort give for their M. benoiti var. 
reinhardti as "distant from the latter group (anals) but at the lower 
profile is the anterior Prc., the posterior high up in the lateral line"
