ledge gained in the interval has brought me however to the position that Collett was probably 

 right, and in that ease the synonymy-list for L. reticitlatits must be augmented by the following names:

This form is known by 3 specimens from West Greenland. One of these is the <>s mm. 

 long specimen') described in detail by Kroyer and figured in Gaimard's Voyages (PI. 7, fig. A 2 ). 

 A second specimen, 43 mm. long, was taken by the Ingolf Expedition of 1895 °^ Sukkertoppen (63 

 24' N.L.) at 68 fathoms depth; the figure cited, painted from the living fish, gives an idea of its 

 appearance. Lastly, Dr. A. Ohlin who was with the Peary Auxiliary Expedition as Zoologist, also 

 obtained a 43 mm. long specimen in Murchison Sound (between 77 — 78° N.L.) at 45 fathoms depth; it 

 is the one of the two specimens which Holmquist (1. c.) has determined as L. liitkenii Coll.; F. A. 

 Smitt has later referred it to L. reticitlatits forma frigida ; of the incorrectness of both determinations 

 I have been able to convince myself by an examination of the specimen itself, which is preserved in 

 the Riks-Mnsenm at Stockholm. 



The most important proportions of these 3 specimens 1 ) are as follows: 



The length of the head is therefore 23,1 — 23,3 °/„, the distance between the snout and the anus 

 43 — 43,6%, the height over the anus 10 — 10,5% of the total length. It is clear therefore, that these 

 young forms are relatively long-tailed in comparison with the adult L. reticitlatits , but this is no 

 absolute objection to their being referred to the named species, because in other Lycodes 1 have 

 observed an approximately similar disagreement between the young and adult individuals (cf. e. g. /.. 

 rossi, p. 57). 



■I Kroyer mentions and figures (PI. 7, fig. 1!) still another specimen, cm, 10 mm. long, but that has been disposed of 

 long since. 



-) The figure is not entirely successful, showing amongst other things not the slightest trace of scales. 



3) Liitken mentions and figures still a fourth L. perspicillum ?», 69111111.10111;, 111 Dijmphna-Togtets zoologist

 as I cannot find it in our collection. Concerning the other L. perspicillum^ from Kara Sea mentioned at the same place.
