On account of the manner of its occurrence the 
Dealfish can be of no economical value to man, though, 
according to information gained by Lilljeborg in Fin- 
mark, it is fairly fat, “but the fat. is soft and oily, and 
readily drains from the body after death.” 
Genus REGALECUS. 
Anterior end of the head truncate , when the mouth is dosed, and formed by the perpendicular loiver margin of 
the under-jaw. Sides of the body , which is silvery, furnished with longitudinal , terete or fat ridges , but without 
spines on the lateral line a . Caudal fin, anal fin and jaw-teeth wanting in full-grown specimens b . Number of 
rays in the dorsal fin more than 200' . Branch iostegal rays 6°. The bottom of the stomach siphoned, elongated 
in a tubular form behind the vent. 
have been perfect in this respect. The most charac- 
teristic point, however, is the structure of the stomach 
and the intestinal canal. Whereas in Lophotes the vent 
lies near the tip of the tail, in Begalecus, as in Tra- 
chypterus, it is placed considerably farther forward — 
in this genus always in front of the middle of the

of the Kings of the Herrings, which was first established 
by Ascanius 7 , but soon afterwards received of Bloch 5 ' 
a name more widely-known since that time, that of 
Gymnetrus, is still more imperfect than of the preceding 
genus. Begalecus ranks in more than one respect as 
r spr ur 
an intermediate form between Trachypterus and Lo- 
photes. The protruded occipital region of the latter 
genus, which appears to a certain degree in the larva? 
of Trachypterus, is fairly distinctly reproduced in adult 
specimens of Begalecus, and in this genus the lateral 
line also extends straight forward along the head above 
the eyes, to judge by the few specimens described that

of the stomach (the posterior end above the pylo- 
rus) is elongated into a long, tubular blind sac, which 
extends back almost to the very end of the tail. 
Still, in other respects, the digestive canal is ex- 
actly similar to that of Trachypterus, as described 
above.
