b. Later Occurrences. Since 1882, when the three young specimens 
were caught in the Trondhjem Fjord, the species has been rediscovered 
at the following places.

In August 1884, Professor Sars caught another fry specimen at Appel- 
ver, north of the Folden Fjord (on the borders of Nordland) at a 
depth of 200—300 fathoms. Its total length was 47 mm., and it 
corresponded, in all details, with the type specimen, but has been 
better preserved, and was about the same size as the latter. 
This is the most northerly point at which this species has up to 
the present been discovered. 
In August 1895 and August 1896, Dr. Storm, at Frosten on the 
Trondhjem Fjord, caught 3 young specimens of the respective total 
lengths of 57 mm., 74 mm., and 120 mm. Of these the one of 
74 mm., is preserved in the Christiania Museum, the others in the 
Museum at Trondhjem. 
The two smaller specimens are of that stage of development 
(subsequently designated as the third) in which the dark and irregular 
cross patches, which proceed from the dorsal to the median line of 
the body, are sharply defined against the lighter greyish-brown 
ground colouring which covers the upper part of the body. Below 
the median line the colouration is still, mainly, a whitish-yellow. 
In the largest specimen, the first traces of the dark ground 
colouring appear also along the anus. In all the specimens the 
scale covering is incomplete. 
Finally, during the Summer 1897, 9 specimens of this species were 
obtained during the deep sea investigations which were then carried 
on in the Skagerak, and Arendal Channel, by Dr. Petersen}, and in 
the Christiania Fjord by Dr. Hjort, most of them representing more 
advanced stages of development, up to that of the almost full grown 
and mature fish. 
These g specimens belonged to the following stages. 
The smallest one, which was caught on the 22nd May, at a depth 
of 80 fathoms, some 30 kilometres West of Lysekil, was of a total 
length of 88 mm., and differed in no respect from the spotted type 
specimen of the medium stage.
