 right, and in that case the s>non\m\-list for L. rettculatns nnist be augmented b\- the following names:

This form is known by 3 specimens from West Greenland. One of these is tlie 65 mm. 

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

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

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

 appearance. Lastly, Dr. A. Ohlin who was with tlie 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 Holmqnist (1. c.) has determined as L. liltkenii Coll.; F. A. 

 Smitt has later referred it to L.retimlatus ioiraz. frigida i \ 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-Museum at Stockholm. 



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



Total length 



Length of the head 



Distance from snout to anus 

 Heifrht over the anus 



15 



28 



6,5 



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

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

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

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

 observed an approximateh- similar disagreement between the \oung and adult individuals (cf. e. g. L. 

 rossi, p. 57). 



M Kroyer mentions and figures (PI. 7, fig. B) still another specimen, ca. 40 mm. long, but that has been disposed of 

 long since. 



2) The figure is not entireh- successful, showing amongst other tilings not the slightest trace of scales. 



3) Liitken mentions and figures still a fourth L. perspicillum? -, 69 mm. long, in Dijmphna-Togtets zoologisk- 

 botaniske Udb3'tte>, 1886, p. 137— 13S, Tab. 17, fig. 6. This specimen was from Greenland (Disko Bay); it must have been lost 

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

 see L. rossi Mahngr. (p. 56).
