LYCODIN/E. 



In later years 2 further specimens of L. sctnimidus have been taken at West C.reenland. One of these, a uniformly 

 coloured female of 335 mm., was taken 1S93 by Dr. E. Vanhijf fen in Utnanak I'jord; it was kindly handed over to me for in- 

 vestigation bv the Berlin Museum. The other was sent to our Zoological Museum in 1901 by P. Mitller of Jakobshavn, 

 governor of the colony; it is only 180 mm. long and of special interest, as in agreement with the above mentioned specimen 

 it shows a not very distinct, 3-et clearh- recognisable, banded marking. 



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

 tion, as a single, uniformly coloured specimen only 128 mm. long; Prof. Collet t 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, /.. seviiniidiis may however also appear with \ery di- 

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

 tunitv, through the kindness of Prof. Sniitt, 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. semimidus by 

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

 /,. scminadus, but in this species he sees only a form of L. retic7ilatus, an opinion I cannot agree with. 



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

 preliminary notice on the Lvcodes of this expedition (1. c. p. 213), I have referred it to L. /I'i/kenii CoW., which again I identi- 

 fied with L. rossi Malmgr. from Spitzbergen, as a small specimen (67 mm. long) from the Ingolf Expedition seemed to me 

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

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

 myself (cf. further p. 56). And since both the specimen of the Ingolf Expedition (that of 180 mm.) and the above-mentioned 

 7 specimens of the Nathorst-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 p;xpedition), which I had erroneously taken for a connecting-Unk with L. rossi. 

 becomes the young form of L. sctniiiudiis (cf. further p. 76 — 77).

Proportions of the distinctly banded form: 



Total length in mm. 



Length of the head — 



Distance from snout to anus — 



Height over the anus — 



The form is elongated, the height over the anus going ca. g",^ — 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'/, 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 bod)-, its distance from tlie snout being 46,1 — 50,6% 

 of the total length; in females its distance from the snout is 44,6 — 48,3*^/0 of the total length. 



') The specimen is from Spitzbergen (North-Atlantic Expedition), the others from West Greenland. 

 2) This specimen is from Jan Mayen (Ingolf Expedition), the others from East Greenland (Nathorst and Kolthoff 

 Expeditions).
