Relation of the species to Lycodes frigidus Coll. 



L. platyrhinus was placed with L. frigidus Coll. by Liitken, and it certainly presents some 



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

 more thorough comparison will at once show important differences of which tin- following max be 

 emphasized. 



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

 length, being 10",, or somewhat more of the total length; the tail especially is quite different in 

 appearance when seen from the side, as it becomes pointed posteriorly somewhat quickly in I., frigidus. 

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

 frigidus has more rays in the pectoral fins, namely 19—21. Lastly, the scaly covering in L. 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 17,3% 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 bauds or spots, blue-black 

 on the bell\\ Lateral line m e di <>1 a t era 1 (?) , only apparent on the trunk. The scales 

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

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

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



Total length Si mm. 



Length of the head 1 | 



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 ol even height, but 

 lessens at the anus, its height here going 12' 2 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 ol the length 

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