accompany any other gulls; Mr. Williams indeed did not take it for 
a gull at all. 
The date of its capture was not noted ; it came into Mr. Thompson’s 
hands November Ist, 1884, and had been then some days dead. It 
was therefore probably shot at the beginning of the last week in 
October. The sex was not ascertained. 
Mr. Henry Seebohm exhibited a fully adult male of Ross’s Gull 
(Larus rossi) which had been shot on the 15th of June, 1885, in the 
neighbourhvod of Christianshaab on the south shore of Disco Bay in 
Greenland, about latitude 69°. It was shot at the nest, and both bird 
and egg were sent by Mr. Paul Miiller to Copenhagen. The egg is 
of exactly the same character as that of Sabine’s Gull (Larus sabiniz), 
but is rather larger, measuring 1°9 by 1°3 inch. Mr. Seebohm 
exhibited a coloured photograph of the egg, which has never been 
obtained before. The bird is so rare that the British Museum 
‘does not possess an example, though there is one in Edinburgh and 
one in Liverpool, from Melville Peninsula, and one in Cambridge, 
besides three in Copenhagen, the last four from Disco Bay. In the 
fully adult breeding bird the delicate salmon-colour of the head, rump, 
and under-parts, contrasting with the black ring round the neck, make 
it an exceptionally beautiful object. ‘The bill is black, the legs and 
feet coral-red with black nails, and the orbits deep orange or pale 
vermilion. 
A communication was read from Prof. R. Collett, C.M.Z.S., con- 
taining an account of the external characters of the Northern Fin- 
whale (Balenoptera borealis). This memcir had been based upon 
the examination of numerous specimens of this Whale killed on the 
coast of Norway during the past summer.

The Entomostraca here described were collected by Professor 
Ralph Tate, of the University of Adelaide, South Australia, and by 
Mr. T. Steel. Prof. Tate’s specimens were sent by him to Prof. T. 
Rupert Jones, F.R.S., to whose kindness I am indebted for the
