whose lengths are from 129—497 nun., it dues not once extend so far, but ceases a little in front of 

 the amis, over the anus or a little behind this. 



Lastly, as regards colouration, none of the present specimens of L. seuiiiiudus , not even 

 the distinctly banded, show signs of assuming the network markings so characteristic of L.reticulatus. 



Taking all together, the differentiating characters seem to me so important, that the reference 

 of these two forms to one species would be quite unnatural. 



If we take L. reticulatiis var. macrocephalus into the comparison, the boundaries between the 

 two species are certainly reduced, so far as the relative sizes of the head and eyes are concerned, but 

 the other distinguishing characters (length of the pectorals, distribution of the scales etc.) still hold good.

In proportions of the total length, the height over the anus is 9,3 — 12%, the 

 length of the head 22- 24,8 ,,, the distance from the snout to the anus 46 — 52 %, the

In the report on the fishes of the Kara Sea, Liitken referred 28 specimens oi a Lycodes to 

 the L. lutkenii described by Collett from the deep water at Spitzbergen. From an examination of 

 these specimens however, I discovered that Liitken had mixed two species together under his /.. 

 lutkenii . as I shall now explain. 



The largest specimen, which is 223 mm. long 2 ), has scales on the tail and .1 great part oi the 

 trunk, whereas the remaining 27 specimens are completely wanting in scales, although amongst them 

 there are specimens up to 186 mm. in length. This alone at the beginning would counsel great caution 

 in bringing these individuals together under one species; certainly one ma\ find in the present treatise 

 many examples to show that variation may occur within one and the same species oi the genus 



■l In well-preserved specimens further, a whole series of dorsal pores tan In- seen. 

 -I Liitken gives the length to 225 mm.
