LYCODIN^. 



colour is brown, more or less dark, with narrow whitish vellow cross-bands whose number varies from 

 5 — 8. Further, as sign of a neck-band, there is a more or less distinct whitish yellow spot immediately 

 over the upper end of the gill-opening, sometimes lower down on the edge of the gill-cover; concerning 

 one of the specimens from East Greenland I have indeed noted: the neck light across over. What 

 especially distinguishes L. eudipleurostictus from the foregoing species in the colouration, is that the 

 vertical bands show no signs of resolving themselves into the characteristic festooned markings of the 

 adult L. esHiarkii. 



When we add to this that the gut immediately behind the stomach is provided with 2 small 

 appendages, whilst the L. esmarkii of Fiumark is wanting in an}- trace of such, we have the most 

 important differences between the present and foregoing species. 



The Greenland specimen yet remains to be briefly mentioned. It was sent from Umanak in 

 1834 and mentioned by Reinhardt sen. amongst the 7 Lycodes which served for the preparation of 

 his detailed treatise on L. vahlii^); its preservation however was not good, and R. when preparing 

 his description, seems to have made no further use of it, otherwise its distinctness from L. valilii 

 might have been apparent to him. Nor did Liitken find anything remarkable in it. Prof. Collet t 

 however, on a visit to our Museum, discovered that this specimen showed signs of a mediolateral in 

 addition to the ventral lateral line usual to L. vahlii']. This fact was for me still more striking: the 

 two lateral lines are especially distinct, just as distinct as in the other specimens of L. eiidiplci/rostict/ts 

 at my disposal. Further, the number of rays in the pectorals agrees with this species and amounts to 

 21, a number that is never reached in L. vahlii. Where the colour is preserved, it is in agreement 

 with the present species. Its length is ca. 275 mm. 



I do not hesitate therefore to separate this specimen from L. vahlii and place it with L. 



eiidipleurostichis. 



Appendix. 



After completing ni}' ]\ISS. on L. eudipleurostictus I have had the opportunity of studxing a 

 series of specimens, caught during my participation in the 1902 summer cruise of the Norwegian 

 steamer Michael Sars . These specimens should be briefl\" described here as they lead to a few 

 changes in the diagnosis. 



The most important measurements of these 16 specimens, likewise of a 17th taken during the 

 1900 cruise of the Michael Sars>, are as follows:

Length of the head —

Put into percentages of the total length therefore, the length of the head in the males is 

 21,2 — 23,6 °o, iu the females and young specimens 19,8 — 22,6 °o; distance between the snout and the 

 anus 36,7 — 40,7 °o; the height over the anus 8,9— 13,3° o-
