Another minor point of difference for Myctoohum hollandl 
is the anterior position of the median branchiostegal photo- 
| phore, though as I have found this variable in other species 
of the genus conclude it may also be a variant here. Mycto** 
hol landl is said to have D. I, 12 though the figure shows 
III, 10, I; the A. given as I, 17 is figured III, 16, I. A 
Still further resemblance of Myctoohum hollandi with Mycto- 
p hum fibulatum is the elevated upper opercular photophore 
nearly level with the lower edge of the eye and the uooer sub- 
i* J- 
pectoral, though not well shown in Parr's figure of Myctoohum 
fibulatum . 
i 
Benthosema pinchotl seems to be an aberrant example of 
the present species, differing only slightly in the suprapector 
al photophore'placed on the beginning of the lateral line, 4 
posteroarials and 21 lower gill rakers.
