ASTERACANTHUS IN THE CORALLINE OOLITE. 
HENRY CHARLES DRAKE, F.G.S., 
Scarborough. 
No remains of this extinct shark have hitherto been recorded in 
the Coralline Oolite of the Scarborough district, and vertebrate 
remains are scarce in this deposit in Yorkshire. 
There are some specimens in the Scarborough Museum, 
with no localities mentioned, but amongst these there are no 
remains of this species. 
Dr. A. Smith Woodward* mentions an  Asteracanthus 
spine being found in the Malton district, but no specimen of the 
Strophodus teeth have yet been recorded from there. It was, 
therefore, a great pleasure to me to find a spine of Asteracanthus 
in the Coralline Oolite of Seamer in lower beds than occur in the 
Malton district. The spine is not perfect, and although I 
searched diligently, I was unable to find the remaining portion. 
It bears the usual tubercles, and the double row of sharp 
tubercles on the hinder surface, but they are much worn, as if 
the spine had been washed about before becoming finally 
buried. 
Dr. A. Smith Woodward kindly examined it, and refers it 
to A. ornatissimus. The specimen is nearly 200 mm. in length, 
and, when perfect, would probably. have measured another 
60. mm. 
A perfect specimen from the Oxford Clay of Fletton, 
Huntingdonshire, of nearly the same circumference at the 
base, measures 320 mm.

How to attract and Protect Wild Birds, by M. Hiesemann, Second Edition 
100 pp., 1/6. London: Witherby & Co. 
This work, the first edition of which was reveiwed in these columns a 
little time ago, has proved so popular that a second edition has been 
called for. This has been revised and brought up-to-date, and many new 
features are included. In Germany the Minister of Agriculture has adopted 
the scheme with the greatest success, and it seems agreed that were it 
adopted by the Public, Government, and Municipal Bodies generally, the 
difficulty of enforcing Bird Protection Acts would become largely un- 
necessary. 
‘A hundred blue books boiled down into one red one’ is a description 
which might be fittingly applied to ‘ Hazell’s Annual for 1911.’ But the 
new number of this old and valued companion is much more than a mere 
digest. of hard, if valuable facts. Indispensable as it is to the writer, or 
the politician, it appeals to a much wider public. The scientist, the small 
holder, the sportsman, the atrist, the photographer—even the idler with 
no special tastes, if such an individual there be—will find matter of interest 
in this encyclopedic guide book to the times in which he lives. Readers 
of ‘ The Naturalist ’ will find the volume particularly useful as it contains 
many facts bearing on their work, There is also an exceptionally good 
index.
