REPORT ON THE DEEP-SEA FISHES. 79 



Ly codes frigidiis. 



Ly codes frigidus, Collett, jSTorsk. Nordh. Exped. Fisk., p. 90, ])1. iii. figs. 23-24. 



The specimens described by Collett under this name were obtained by the North 

 Atlantic expedition in the tract of ocean surrounding Bear Island, Spitzbergen, and also 

 on the banks of Heligoland and Lofoten. The depth varied from 260 to 1333 fathoms. 

 The " Knight Errant " met with the same species in the Faroe Channel, capturing a great 

 number of young and half-grown specimens on the 17th August 1880, at Station 8, in 

 540 fathoms, and in August 1882, at Stations 8 and 9, in 608 and 640 fathoms. Some 

 of these specimens agree perfectly with the characters assigned to the species by Hr. 

 CoUett (who had the kindness to send to me one of his own specimens for comparison), 

 but other specimens of the same size from the same haul, and possibly of the same brood, 

 show variations in the development of the lateral line and in the extent of scaling, so 

 that it would have been difficult, or rather impossible, to identify them from the descrip- 

 tions only. And it seems to me very doubtful whether the lateral line and the scaling 

 should be employed, in the fishes under consideration, so positively for specific distinction 

 as has been attempted by Liitken and Collett.

First known from two examples, 3-j and 6j inches long, obtained off north-western 

 Spitzbergen, in 260 and 459 fathoms, and lately recognised by Ltitken in specimens from 

 the Kara Sea, which were caught at a depth of between 46 and 106 fathoms.

Known from two examples, one from Greenland, and the other from Spitzbergen 

 (260 fathoms). 



Lycodes murcena (PL XIL fig. A). 



Lycodes murorna, Collett, Norsk. Nordh. Exped. Fisk., p. 116, pi. iv. figs. 29-31. 



Of this interesting species many specimens were collected during the cruise of the 

 "Knight Errant," viz., at Station 8 (August 17, 1880) in 540 fathoms, and at Station 9 

 (August 23, 1882) in 608 fathoms. The typical specimens came from banks lying off
