1882. | MR. F. DAY ON ANGUILLA KIENERI. 537 
Collett has remarked, to determine the species of this genus is at all 
times difficult, owing to the unsatisfactory condition of the older type 
specimens, as well as the great individual variations in proportions, 
colour, and amount of scaling that occur among examples of the 
same species, and which may sometimes be due to sexual conditions. 
It admits of the clearest proof that the young and adult indivi- 
duals of the same species exhibit marked dissimilarity. 
The example is 33 inches in length ; its head is one seventh of the 
total length, and the greatest height of the body one fourteenth of the 
total length; the height of the head is two fifths of its length, and 
but little less than its width. Eyes comparatively large, being 
about one fourth of the length of the head, one diameter from the 
end of the snout, and less than one diameter apart. Teeth in the

jaws, vomer, and palate. Scales existing from the head and back of 
the pectoral fin backwards over the body. It seems as if only one 
lateral line were present. The fins are too much stiffened for it to be 
possible to count the fin-rays; the pectoral turned forwards reaches 
the middle of the eye; the ventrals, consisting of one or two rays 
each, are rather more than half as long as the eye. No open glands 
are visible on the cheeks and gill-covers ; but three are placed along 
the edge of the upper jaw, and some along the lower jaw. 
My principal reasons for directing attention to this specimen are, 
first, to point out that the Mediterranean Anguilla kieneri has not 
yet been obtained from our coasts, and consequently is not entitled 
to any place in the British Fauna; secondly, to show that the 
Arctic genus Lycodes is represented by this wrongly determined 
specimen. But to what species the fish belongs I do not consider suffi- 
cient data are at hand on which to form a definite opinion.
