LUMPENUS MACULATUS. 
Plate XI, fig. 4. 
Teeth on the palatine hones and vomer, as well as in the jaws; and among the jaw-teetli, in both jaws, in front, 
a pair of distinct canine teeth. Length, of the maxillary hones more than Vs of that of the head. Number of 
rays in the dorsal fin less than 62, in the anal less than 39. Upper part of the pectoral fins arcuate, lower part 
elongated, with the rays free at the tip. Caudal fin truncate or slightly rounded.

All the specimens of this species that Fries ob- 
tained on the coast of Bohuslan were between 150 and 
175 mm. in length. The body is not so elongated as 
in the preceding species, and of more uniform breadth, 
only slightly tapering towards the tail, moderately com- 
pressed throughout its length, and with broad, rounded, 
dorsal and ventral edges and a longitudinal depression, 
as in the preceding species, along the middle of the 
sides. The greatest depth of the body is from about 
8 to 10 % of the length, and the greatest breadth nearly 
3 / 4 of the greatest depth. The head, which measures 
about 16 or 17 % of the length of the bod}^ a , is some- 
what rounded at the top, like the latter, with the snout 
curved, sometimes tumid with a quantity of the same 
substance as the so-called adipose membrane, and pro- 
jecting distinctly in front of the jaws. The cheeks are 
tumid with strong masticatory muscles. The eyes are 
large (their longitudinal diameter being about 23 % of 
the head), turned slightly upwards and only a little 
distance apart. The length of the snout is about the 
same as that of the eye, the hind margin of which is 
consequently placed, as in the preceding species, some- 
what in front of the middle of the head. The nostrils 
are small, and their arrangement the same as in the 
preceding species; but in this species the two pairs of 
small openings which have been regarded in this light, 
one in front of, and one behind, the more distinct 
dermal tube, are covered and generally hidden by the 
adipose, membranous integument*. The gape is turned 
somewhat obliquely upwards. The upper jaw, as in 
the preceding species, is only slightly movable, and 
does not admit of any protrusion, as the bones which 
form the jaw, the narrow and linear intermaxillary 
bones and the maxillaries, are closely united by short 
ligaments. The maxillaries, which are longer than 
in the preceding species, and are hardly any wider 
behind than in front, form a slight S-curve, and ex- 
tend behind the perpendicular from the centre of the 
eye. A broad, labial skin is rolled over the inter- 
maxillary and maxillary bones, and the margin of the 
jaws is somewhat arcuate. The branches of the lower 
jaw, which is long, and curved slightly upwards, but 
is still shorter than the upper jaw, are almost parallel. 
It is only the lower jaw that is moved when the mouth 
is opened. In the extreme front of both jaws we find 
large, prominent, canine teeth, one on each side in the 
upper jaw, and two in the lower. In the upper jaw 
there is an empty space between them; but in the 
lower jaw this space is filled by a row of much smaller 
teeth, behind which the whole front surface of both 
“ In small specimens, from 66 to 69 mm. long, according to Collett, the length of the head is 17'4 % of that of the body.
