Occurrence of the Grey Seal (Halicherus grypus) in the Mersey.— 
An adult male Grey Seal was shot in Paddington Lock, on the 
Woolston New Cut of the River Mersey, over two miles, by the river, 
above Warrington Bridge. It was driven into the lock and killed on 
June 17th, 1908. For two or three days before it was killed two 
Seals had been noticed between Atherston Quay and Warrington 
Bridge, and several unsuccessful attempts were made to shoot them. 
In order to reach the Cut the Seal must have ascended Howley Weir, 
Latchford, which it probably did at high tide. The animal, which I 
examined in the flesh, measured :—From nose to tip of tail, 7 ft. 6 in. ; 
from nose to longest toe of hind foot, 8 ft.; length of fore flipper, 
14 in.; length of index toe-nail, 24 in. ; girth of body posterior to fore 
flippers, 4 ft. 8 in.; length of head, 14 in.; length of incisor teeth, 
3 in.; length of hind flipper, 15 in.; width of hind flipper, 18 in. ; 
length of tail, 7 in. The teeth were not crowded, nor were they dis- 
tinctly tuberculated; the nasal opening was typically large. Mr. 
T. A. Coward has seen the skin and skull, and confirms the identifica- 
tion; he has seen the Grey Seal off the coasts of Lleyn and Anglesey, 
where it has occurred on several occasions, and is of opinion that the 
species may breed on the North Wales coast. This is the second 
recorded instance of the occurrence of the Grey Seal in the Mersey, 
the previous one being in the winter of 1860-61, when one was cap- 
tured in the Canada Dock, Liverpool (Proc. Liv. Lit. & Phil. Soe. xv. 
p. 134, 1860-61; Proc. Liv. Biol. Soe. iii. p. 263, 1888-9). The present 
specimen has been obtained for the Warrington Museum.—G. A. 
Duntor (Warrington Municipal Museum).

Mimicking Song of Chiffchaff.—It may interest your correspondent, 
Col. H. Meyrick, to know that when at Bettws-y-Coed in April, 1905, 
I heard a very similar “‘combined” song. The bird began with a 
normal ‘ chiffchaff,” three or four times repeated, then suddenly
