i.ycodin.e. 



In later years 2 further specimens of L. seminudus have been taken at West Greenland. One of these, a uniformly 

 >ured female of 335mm., was taken 1893 by Dr. E. Vanhoffen in Umanak Fjord: it was kindly handed over to me for in- 

 vestigation by the Berlin Museum. The other was sent to our Zoological Museum in 1901 by P. 51 filler of Jakobshavli. 

 governor of the colony; ii is only [80 mm. long and of special interest, as in agreement with the above mentioned specimen 

 it shows a not very distinct, yet clearly recognisable, banded marking. 



Apart from West Greenland /.. seminudus was again found at Spitzbergen by the Norwegian North-Atlantic Expedi- 

 tion, as a single, uniformly coloured specimen only 128 mm. long; Prof. Collett has kindly handed it to me for study and I 

 can confirm the correctness of his determination. 



In addition to the uniformly coloured or weakly banded form, /.. seminudus may however also appear with very di- 

 stinct cross-bands and with a light band across over the neck. In the Riks-5Iuseum of Stockholm I have had the oppor- 

 tunity, through the kindness of Prof. Smitt, to see no less than 7 specimens (129—280 mm. long) from East Greenland 

 (Nathorst and Kolthoff Expeditions of 1899 and 1900) of a form, which only differs from the typical L. seminudus by 

 the pronounced, livelier marking. In his treatise of 1901 F. A. Smitt had rightly referred these specimens to Reinhardt's 

 /.. seminudus, but in this species he sees only a form of L. reiiculatus, an opinion I cannot agree with. 



A similar specimen 1180 mm. long) had also been taken by the Ingolf Expedition south from Jan Mayen. In my 

 preliminary notice on the Lycodes of this expedition (1. c. p. 213), I have referred it to L. liitkenii Coll., which again I identi- 

 fied with L. rossi Malmgr. from Spitzbergen, as a small specimen 167 mm. longl from the Ingolf Expedition seemed to me 

 a transition-form between L. rossi and the larger specimen from the same expedition referred to L. liitkenii. This position I 

 have meanwhile been obliged to give up. L. rossi Malmgr. is without doubt the young stage of L. celalus established by 

 myself (ci. further p. 561. And since both the specimen of the Ingolf Expedition (that of 180 mm.) and the above-mentioned 

 7 specimens of the Xathorst-Kolthoff Expeditions seem constantly to have very short pectorals, whereas L. liitkenii Coll. is 

 characterized specially by large pectoral fins, I consider it best to keep the last named separate from L. seminudus. And the 

 small specimen referred to (from the Ingolf Expedition), which I had erroneously taken for a connecting-link with L. rossi, 

 becomes the young form of /.. seminudus Icf. further p. 76 — 77I.

Proportions of the distinctly banded form: 



Total length in mm. 



Length of the head — 



I listance from snout to anus — 



Height over the anus — 



The form is elongated, the height over the anus going ca. 9 1 \— 11 times in the total length. 

 The greatest thickness lies forward on the cheeks and is equal to or somewhat greater than the 

 height at the same place; the trunk is tolerably compressed, its height midway being i x / 2 greater 

 than the thickness, and the tail becomes more and more slender posteriorly. The anus in the males 

 lies at, or a little in front of, the middle of the body, its distance from the snout being 46,1 — 50,6% 

 of the total length : in females its distance from the snout is 44,6—48,3 % of the total length.
