LYCODIN^. 



brown with a light spot on each side of the neck (sometimes a light stripe across 

 over the neck), and with 5 — 8 as a rnle narrow whitish yellow cross-bands over the 

 ■trunk and tail (sometimes partly assuming a ring-form). The scales cover the whole 

 of the bod}' to in front of the dorsal fin and to the ventrals, and extend out on to the 

 unpaired fins. The lateral line is double, divided just behind the root of the pectoral 

 into a mediolateral and a ventral branch, both distinct. P\'loric appendages 2. Size 

 reaches to 325 mm. 



D. 100 — 103. A. 88—92. P. 20 — 22 (23). Vert. 106 (20-^86). 



Distribution. Northerly West- and East-Greenland, ca. 150 — 400 fathoms; Spitz- 

 bergen, 260 — 460 fathoms; west from Lofotens in Norway, 350 fathoms; off Norway- 

 Shetland Slope , 360 — 420 fathoms; north from the Fseroes, 470 fathoms; east from 

 Iceland, 300 — 340 fathoms. 



I have been obliged to found this new species for the 4 specimens brought home by the 

 Norwegian North-Atlantic Expedition from Spitzbergen and from the seas off Lofoten, which Prof. 

 Collett after some reflection, considered were young specimens of L. esntarkii of Finmark, also for a 

 similar specimen (260 mm. longi taken by the Ingolf Expedition north-west from the Fseroes (figured 

 in fig. I a of Tab. III). In addition, there is a further specimen from Umanak in West Greenland, 

 referred formerly by Reiuhardt sen. to the Z. z/a/^/// founded by him. Lastly, I have been able to 

 examine 4 specimens in the Stockholm Riks-Museum, taken in Franz Joseph's Fjord (northerly East 

 Greenland) by the Nathorst and Ko 1th off Expeditions, and considered by Prof. F. A. Smi tt as 

 «forms-; of L. valilu'^). 



As I shall now proceed to confirm the necessity of the resolved upon separation from L. esmarkii\ 

 I ma\- first of all set down the proportions of the 9 specimens. 2)

The form of the body is on the whole not unHke that of L. esmarkii\ and the inost important 

 proportions are somewhat similar; thus, the length of the head amounts to 21,9— 24,3° o, the distance 

 between the snout and the anus to 38,9 — 41,4 °o of the total length. 



The fins on the other hand .show in several -wa^'s, tolerably great differences from those of 

 the foregoing species. Whilst the pectorals in L.esinarkii have 22—23 rays, the number in the present 

 species is mostly 21, more rarely 22, only in a single specimen and in one of its pectoral fins is the 



■1 My original diagnosis (1. c.) has been changed somewhat out of regard for these 4 specimens (likewise also for the 

 still later obtained 17 specimens of the (Michael Sars» Expeditions of 1900 and 1902 [cf. p. 36]). 



2) The West Greenland specimen is in a tolerably bad condition and will therefore be described by itself (p. 36). . 



3) Collett has 160, which must be a misprint.
