THE ZooLocist— AvuGust, 1875. 4571 
The beak is of the usual shape, about five inches and a quarter 
by three inches and a half, of a dark reddish brown colour, with a 
large tooth in both margins of the inner mandible, and a much 
smaller notch on each side of the outer mandible. The horny 
sheath of the tongue is also of a brownish colour, and is studded 
with six or seven rows of small teeth pointing backwards. 
The short arm is much mutilated and decayed,—all the rings 
have fallen from the suckers,—but when fresh, Sergeant O’Connor 
measured it as eight feet in length and fifteen inches round the 
base. 
Our specimen is provisionally labelled Architeuthis Dux, in the 
belief that it is identical with the Danish species so named by 
Steenstrup, and the few perfect suckers which we have closely 
resemble the figure given by Bronn of a sucker of Architeuthis. 
It will be observed that the large size of the outer suckers along 
the margin of the club clearly distinguish our specimen from the 
Megaloteuthis Harveyi (Kent), lately taken in Newfoundland, in 
which the outer suckers are described as minute, while the crowded 
mass of suckers in six rows at the base of the club will equally 
serve to remove our present subject from any of the known species 
of Ommastrephes, to which genus, however, it is probably closely 
allied. 
I believe that only two other instances are known of these 
gigantic cuttles, or “king squids,” as we might call them, being 
taken in British waters. One is recorded by Mr. Gwyn Jeffreys as 
having occurred in Shetland. Another, stranded on the shores of 
Kerry more than two hundred years ago, has lately been introduced 
to the readers of the ‘ Zoologist,’ under the name of Dinoteuthis 
proboscideus, and was probably very different, with a much broader 
form of body. These oceanic monsters may include more than 
one genus and many species.

Mouse eating Mlies—A few days ago I captured an immature male 
specimen of the common mouse (Mus musculus). I gave it bread-crumbs, 
but it took no notice of them. A large blow-fly happened to be buzzing 
against the window-pane, when it just struck me I would try the mouse 
with it. I did so: the fly was instantly seized and demolished in a few 
minutes, with the exception of the wings and legs. Cheese—that all- 
powerful seducer of the mouse—was tried, but it was neglected also. I tried
