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 ?i, of the length, and the greatest Ijreadth nearly 

 ^/^ of the greatest depth. The head, which measures 

 about 1() or 17 % of tlie length of the bodj'", is some- 

 what rounded at the top, like the latter, with the snout 

 curved, sometimes tumid witli a quantitj' 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 2/5 96 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, tlie hind margin of \v'hich is 

 consequentlv 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 upwai'ds. The upper jaw, as in 

 the preceding species, is only slightly movable, and 

 does not admit of anv protrusion, as the bones which 

 form the jaw, tlie narro^v and linear intermaxillary 

 bones and the maxillaries, are closely united by short 

 ligaments. The maxillaries, Avhich 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 shortei- than the upper jaw, are almost parallel. 

 It is onlv 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 jnw, and two in the lower. In the upper jaw 

 there is an cmptv space between them; but in the 

 lower jaw this space is filled by a row of much smaller 

 teeth, behind whicli the whole front surface of both 



" In small specimens, from Ci{) to 69 mm. long, according to Collett, the length of the head is 17'4 »« of that of the body.
