larger weighing 144 oz. and measuring 13} inches, and the smaller weighing 
53 oz. and measuring 9% inches. Mr. Backland, who examined them, 
reports that they were young Bull Trout. The stomach and throat of the 
largest of these fish was as full as it could be of Whitebait, upon which it 
had been feeding. It was fat to an extraordinary degree, the pylories being 
so covered with fat that it was with difficulty they could be counted. Both 
fish were silvery, with fins a faint yellow, tail square, and on its edge a 
darker line; the adipose fin tipped with red: the body covered with spots, 
descending a long way below the lateral line. In life these spots must have 
been of a dark brown colour. Mr. Buckland was puzzled to know whence 
these fish could have came, but believed them to be truly wild, and not 
artificially bred. For some years past he has been in the habit of receiving 
specimens of this kind of Trout from the mouth of the Thames about the 
time that the Whitebait make their appearance, and he has no doubt that 
they follow the shoals to feed upon these small fry. The man who caught 
them was fishing for Flounders, and it is satisfactory to think that the water 
is now sufficiently purified to enable not only Flounders but Salmonoids 
to live in it. A considerable portion of the London sewage being now taken 
down into the estuary by the main-drainage works, the mid-portion of the 
river is said to be comparatively clear.—J. E. Harrine. 
GREENLAND BULLHEAD at BricHTon AND SouTHEND.—-According to 
Couch, this species, Cottus grenlandicus, has only once been recorded from 
any part of the British seas, and then from the coast of Kerry. During the 
past month I have received three living specimens, about six inches in length, 
captured between Shoreham and Brighton: and several other specimens 
arrived last night (March 16th) of about the same size, taken in the White- 
bait nets off Southend, in the estuary of the Thames. ‘The remarkable 
part of this occurrence is that I have from time to time during the last 
four years received large numbers of other species of the genus Cottus 
which inhabit our coasts, but never before saw examples of the Greenland 
Bullhead. I forwarded three examples to my friend Mr. Francis Day, who 
has compared them with Greenland specimens from the Leyden Museum, 
and thus kindly confirmed my identification. Yarrell, in his ‘ Natural 
History of the Fishes of Britain,’ makes no meution of this species, but in 
the Supplement reference is made to the Kerry specimeus, and the species 
is there well figured. Dr. Giinther, in his Museum Catalogue, simply 
gives Arctic seas of America as the habitat, but I believe it is also taken 
in the extreme north and west of Europe. The Greenland Bullhead grows, 
I understand, to a large size in the waters east of Greenland, and is there 
esteemed as an article of food. This species might easily, in its younger 
stages, be passed amongst a batch of Bullheads (Cottus scorpius) or Father- 
lashers (Cotlus bubalis), being superficially like the latter. A second look,
