then arctic-alpine fauna withdrew in the same direction, so 
that the arctic regions and the high mountains received the 
previously mentioned fauna. In the arctic regions, and on 
the higher Alps, therefore, the descendants of the Tundra 
fauna should be searched for. While ascending the mountain 
slopes there remained in many lower places, colonies in moors, 
heaths, and on cold temperate hills, in moist and cold ravines, 
the rest of the glacial fauna. These samples, isolated and in 
small parties, spread over a large territory as islands in the great 
ocean of the widespread Middle-European Molluscan World.’

FOSSILS. 
Cestracion sp. from the Yorkshire Chalk. — I recently 
obtained a tooth of Cestracion sp. in the Red Chalk at the foot 
of the cliffs at Speeton. This species does not appear to have 
been previously recorded for the Yorkshire Chalk, though it 
occurs in the Gault and Yectian for the South of England. It 
has been placed in the museum at Hull. — G. Sheppard,

FISHES. 
Electric Ray at Filey. — A report appeared recently in 
the local press stating that an Electric Ray had been taken in 
Filey Bay, and that the fish was shaped like a bass fiddle, 
and measured a yard and a half in length. The information 
reached me too late to enable me to see the fish, which had 
not been preserved, but by the aid of several Filey friends, 
I have been able to get a detailed description of it and 
the circumstances of its capture. It was caught on June 
29th in a salmon net by a man named W. Richardson, 
who received several shocks while handling it. Not liking the 
un canny beast and having no curiosity regarding it, he left 
it on the beach, where it was presently found by a man named 
H. Jayes, who brought it into Filey and exhibited it in the 
streets. It was not actually measured, but is estimated by 
several people who saw it to be two and a half feet in length, 
and was described as black on the top, and white beneath, 
with the skin smooth like rubber. Behind the eyes were 
two small circular ‘ blow-holes ’ with perfectly smooth edges, 
not serrated in any way. The details of this description, 
and especially the smooth edges of the temporal spiracles 
leave no doubt that the fish is the Torpedo nobiliana of Yarrell. 
a species which seems to appear on rare occasions on the 
southern coasts of England and Ireland, but of whose occurrence 
in Yorkshire waters I can find no previous record. —
