the other species, and, perhaps because of the larger eye, the maxillary reaches only 
to the posterior margin of the eye, whereas it reaches well beyond this point in large 
specimens of the other species. The snout projects more prominently beyond the 
mouth with age in all the species, and it becomes quite conical, though a little de- 
pressed in chuss. 
The chin barbel remains short throughout life in regius and chuss, in which it 
never exceeds the pupil of the eye in length. In large specimens of Jioridanus and 
earlli it is nearly or quite equal to the diameter of the eye. 
The third ray of the first dorsal is greatly produced in adults of chuss, reaching 
about to the end of the first third of the second dorsal. It is not evident at what 
size the ray becomes produced from the specimens at hand, as fish ranging from 70 
to 185 mm in length are missing. In the smaller fish it is not produced, but in the 
larger ones it is long. In all the other species the first dorsal becomes rather pointed, 
but none of the rays are especially produced. The differences in the length and shape 
of the other fins remain about the same as in smaller specimens already discussed. 
The differences in color remain virtually the same as in the smaller specimens 
described in the immediately preceding section. The general color of earlli remains 
much darker than in any of the other species. A specimen about 100 mm long is 
uniform dark brown, with the vertical fins almost black. Larger fish sometimes are 
more or less blotched with pale color. No deep black is evident on the first dorsal, 
as in the other species herein considered. Of these, regius differs strikingly in having 
the deep black color of this fin margined with snow white (figs. 140 and 141). 
DISTRIBUTION OF THE YOUNG 
It is shown under the heading, “Spawning,” that the early larvae, under 5.0 mm 
in length, apparently consisting of both regius and jioridanus, the only common 
species of Urophycis at Beaufort, were taken only at stations 6 to 13 miles offshore,
