ARCTIC SEA-CATS.

original of our figure. Its length ivas 914 mm. In 
this specimen too, the distance between the anal fin 
and the tip of the snout is less than half the length 
of the body; and thus Anarrhichas minor , like the 
preceding species, is probably distinguished in this 
respect from the following species; but the variations 
in the specimens from Greenland mentioned above throw 
a doubt on the constancy of this character. In Todd’s 
figure of An. minor (in Bean, 1. c.) the beginning of 
the anal fin is also very near the middle of the body. 
In our specimen the roAv of vomerine teeth is scarcely 
any longer than the palatine rows. The former i*oav, 
which consists of six teeth, the two posterior pairs 
being obtuse (the one tooth of the innermost pair even 
fiat), the front pair obtusely pointed and shoiving more 
lateral compression than the others, is 28'5 mm. long; 
Avhile the roAv on the right palatine bone is 28 mm. 
long, and consists of 10 pointed teeth. All the teeth 
are red — Stenstrup explains this as due to the cir- 
cumstance that sea-urchins compose the chief food of 
the fish ■ — , but the jaw-teeth and palatine teeth are 
Avhite at the point. 
The Spotted Sea-cat has long been knoAvn in Ice- 
land and Greenland as a still more useful fish than the 
preceding species. Zouieav Avas the first to describe it 
as belonging to the White Sea and the north coast of 
Russia; and Esmark the first to publish an identification 
of the European Anarrliiclias pantherinus with the 
Iilyre of Iceland. In the North this species is more 
common than the preceding one — off Vardo, according 
to Sp ARRE-ScHNEiDER, it is taken in large quantities — ; 
but southwards its geographical range seems to end 
in the neighbourhood of Bergen. On the American 
coast it has been met with in the Bay of Fundy". It 
seems generally to keep to deep water, descending to 
at least as great a depth as 200 fathoms (Collett). 
Its food is of the same nature as that of the preced- 
ing species. 
THE BLUE SEA-CAT (sav. blaa hafkatten). 
ANARRHICHAS LATIFROXS. 
Plate XIII, fig. 2. 
Length of the pectoral fins less than 13 % of that of the body. Vomerine row of teeth shorter than the row on 
each of the palatine bones. The dorsal fin ends in » an even curve down to the base of the caudal fin. Top of 
the frontal bones behind the eyes at least as broad as the interorbital space. Colouring dark grayish brown or a 
lighter chocolate-colour , with indistinct , round or rounded quadrangular , black spots , partly arranged in slightly 
marked , transverse bands across the back.

Obs. On reading Collett’s description (Forh., 1. c., 1879, p. 
57) of the teeth in Anarrhichas latifrons, and comparing it with 
Kp.Dyer’s figures of the teeth in Anarrhichas denticulatus, we find so 
close a correspondence between them that we can hardly escape the 
conclusion that they both refer to this species. Nor is KrOyeb’s 
“ Brown-Goode, Fish. a. Fish. Industries of U. S., sect. I, p 
figure of the external appearance of the fish incompatible with this 
opinion, especially if we remember Steenstrup’s observation (Vid. 
Meddel., I. c., p. 179) that this figure is probably drawn from a 
badly-preserved specimen, the snout of which may very likely have 
been flattened. Still, in this figure the caudal fin, the pectoral fin, 
and the head are longer than in Anarrhichas latifrons, according to 
our present knowledge of it; and we ought, therefore, not yet to 
deny the possibility of grounds for Steenstrup’s assumption that a 
fourth species of this genus may await our further investigations, and 
that for it should be reserved the name of An. denticulatus. 
This species too, with our present knowledge of 
its individual peculiarities, is externally very like the 
two preceding ones. The snout, hoAvever, is more 
pointed. The deeper form of the body, the greatest 
depth being more than 22 % of the length, may also 
occur, according to Bean’s measurements, in large spe- 
cimens of Anarrhichas lupus; and in this case the cha- 
racter Avhich might othenvise be employed, that in the 
249 .
