NOTES AND COMMENTS. 
ROSEBERRY TOPPING. 
Wuen the Yorkshire Naturalists’ Union visited Guisborough 
last year (see ‘ Naturalist,’ Nov. 1906, pages 393-394), Mr. J. J. 
Burton pointed out that the levels and thicknesses of several of 
the zones appearing on Roseberry Topping are incorrectly given 
by the Geological Survey. He therefore kindly prepared the 
Lower Qolzée.

section, reproduced herewith, which may be taken as approxi- 
mately correct. Mr. Burton is engaged in investigating this 
curious hill, respecting which there are a number of interesting 
problems, and we hope to give our readers the results of these 
investigations later. 
BRITISH EGGS OF PALLAS’ SAND-GROUSE. 
By the permission of the Editor of the ‘Transactions of the 
Hull Scientific and Field Naturalists’ Club,’ we are able to present 
our readers with a coloured plate, representing, in actual size, 
the only four British eggs (two clutches) of the Pallas’ Sand- 
grouse known to exist. From a note in the Transactions just 
referred to, we gather that both clutches were obtained on the 
high wolds west of Beverley, one on June 15th, and the other 
on July 5th, 1888. They are by no means the only eggs laid 
during that extraordinary immigration of 1888, as some of the 
broken egg-shells were found on the fields. The eggs herewith 
figured (Plate XIII.) came into the possession of the late Johnson 
Swailes of Beverley, whose fine collection (minus these four, 
which are owned by Mr. T. Audas) is now in the Hull Museum.
