The correspondence between these measurements is sufficient to show that the 
Greenland specimen is at least very close to the Newfoundland Sulphurbottom, if 
not identical with it, which probability is strengthened by many points in Mdller’s 
description. The chief differences shown here and in the other data given by 
Moller are: (1) the dorsal fin is lower; (2) the color is black. 
Regarding these points it may be said, first, that in view of Eschricht’s remarks 
regarding the dorsal fin, it is uncertain whether Moller measured the height in the 
same manner as myself; second, Moller’s specimen had been dead three days when 
he saw it and perhaps much longer, so that it is quite natural it should be described 
as black. It is to be noted that the parts protected from the light are described as 
gray. 
The case of this Greenland specimen (and the species it represents) remains, 
therefore, substantially as Eschricht left it, namely, with a very strong probability 
that it was identical with B. musculus (L.), but with positive determination impos- 
sible from lack of more extended data. 
‘This length is from the tip of the mandible to the notch of the flukes. In computing the 
percentages here and on p. 159, eighteen inches were subtracted for the overhang of the lower jaw.
