MAMMALIA. 
Rudolphi’s Rorqual (Balenoptera borealis) —It may be interesting, 
as a record of a little-known mammal in the British Isles, to state 
that a ‘‘ Bottle-nosed Whale,” forty-five feet in length, and estimated 
to weigh about thirty tons, washed up on the beach near Hauxley 
Point, about the middle of, the Northumbrian coast, early in February, 
1912, has proved to be an example of Rudolphi’s Rorqual (Balenoptera 
borealis, Less.), of which we had mo previous good record for North- 
umberland, though several of the allied species have been satisfactorily 
identified there, and from time to time more or less doubtful animals 
have been cast ashore. In September, 1872, a specimen of B. borealis, 
some thirty-seven feet long, was stranded and captured near Bo'ness, 
on the Forth, and its skeleton secured and prepared for the Anatomical 
Museum of Edinburgh University by Prof. Sir William Turner, who 
read a paper upon it to the Royal Society of Edinburgh on Feb. 20th, 
1882, at which date it appears to have been the first authentic record 
for Great Britain. The skeleton of the Hauxley specimen has been 
secured for the Hancock Museum, Neweastle-on-Tyne, and I am 
indebted for confirmatory information of its identity to Prof. Meech.

AVES. 
Nocturnal Movements of the Redwing (Turdus iliacus).—In the 
last number of ‘The Zoologist’ (ante, p. 72) Mr. F. J. Stubbs con- 
tributes some further interesting observations on ‘‘ Nocturnal Red- 
wings,’ upon which, if space allows, I should like permission to 
comment. Mr. Stubbs’s strongest point seems to me to be the 
undoubted fact that the Redwing’s ‘‘seep” or ‘‘tzee”’ is so much 
more frequently heard during the dark hours of October and November 
than the cries of other migrant Passeres ; and itis not easy to under- 
stand why this should be so, on the ordinary view that normal 
migration is an all-sufficient explanation. Personally, I have never 
heard the Blackbird’s softer but similar migration-note at night, a 
fact which has often puzzled me. The Song-Thrush (whose note 
can hardly be considered as very like that of the Redwing), on the
