Relation of t li e species to Lycodes frigidiis Coll. 



L. platyrhhiiis was placed with L. /n't^jdns Coll. by Liitkeii, and it certainly presents some 

 resemblance with this sjjecies in appearance, uameh-, in its uniform, ruddy brown-gray colour; but a 

 more thorough comparison will at once show important differences of which the following may be 

 emphasized. 



L. frigidus has a less elongated body-form, the height over the anus, in a specimen of similar 

 length, being lo " o or somewhat more of the total length ; the tail especially is quite different in 

 appearance when seen from the side, as it becomes ])ointed posteriori)- somewhat quickly in L. frigidus. 

 Again, the head is larger in L. frigidus , its length being 22",, or more of the total length. /.. 

 frigidus has more rays in the pectoral fins, namely 19—21. Lasth-, the scah' covering in /..frigidus 

 is far advanced at the total length of the present species, and its lateral line is single (ventral).

The height over the anus is 8",, of the total length. The head is small, its 

 length being only i 7 , 3 " ,> of the total length. The tail is much longer than the head 

 and trunk together, the distance from the snout to the anus being 38,3",, of the total 

 length. The colour is a uniform yellowish white, without bands or spots, blue-black 

 on the b e 1 1 >-. Lateral line m e d i o 1 a t e r a 1 ( ? ) , o n 1 \- apparent on the trunk. The scales 

 extend to the point of the pectoral fin, but naked spots occur here and there, 

 especiallv on the tail posteriorly; incipient scale-formation on the unpaired fins. 

 Size 81 mm.

Only one specimen is present for examination. Its most important proportions are the following: 



Total length 81 mm. 



Length of the head 14 — 



Distance between the snout and the anus 31 — 



Height over the anus 6,5 — 



The form of the body is somewhat elongated; the greatest height lies over the belly a little 

 in front of the anus and goes 10 times in the length. The trunk itself is almost of even height, but 

 lessens at the anu.s, its height here going 12' ^ times in the total length; the tail tapers slowly and 

 fairly evenly towards the point. The greatest thickness lies across the cheeks and is but little less 

 than the greatest height of the body; the trunk is a little smaller, and the tail becomes more and 

 more compressed towards the tip. The anus lies a long distance in front of the middle of the length 

 of the body, its distance from the snout being 38,3",, of the total length.
