is taken on the Yorkshire coast, as from the researches of 
Montagu and Yarrell it is apparently absent from the east 
coast of England, its place being taken by the true Smelt 
(Osmerus eperlanus), which, in its turn, is absent from the 
south coast, where the Atherine is abundant.

Resident, local, not abundant, except at Spurn Point, where 
Mr. Winson reports it as common in July. ‘The ‘Grey 
Mullet’ is included in the lists for Scarborough (Murray, 
1832) and for Redcar (Ferguson, 1860). It is occasionally 
caught in summer at Whitby; and has been taken at 
Skinningrove, near Saltburn. 
The distribution on the Yorkshire coast of the various species 
of Grey Mullets as described by Dr. Giinther—since the 
publication of the last edition of Yarrell’s B. Fishes— 
requires investigation. Dr. Giinther informs us that he is 
of opinion that all the species may possibly occur on the 
east coast. 
ito. Mugil auratus Asso. Long-finned Grey Mullet. 
eee Mugil septentrionalis Ginth. Lesser Grey Mullet. 
The only authority for including this species in the Yorkshire 
list is the statement by Meynell (1844) that the two species 
of Grey Mullet (AZ chelo and MZ. capito) are occasionally 
taken on the Yorkshire coast.
