6 Notes and Comments. 
LOWER PAL/ZEOZOIC ROCKS OF CAUTLEY. 
In a paper ‘ On the Lower Paleozoic Rocks of the Cautley 
District,’ recently read to the Geological Society, Prof. J. E. 
Marr suggests the following classification for the Ordovician 
rocks of the area :— 
peice Shales. : } 
| Beds above the Volcanic Group. | 
ASHGILLIAN.~ Contemporaneous Volcanic Group. ;Staurocephalus Beds. 
Beds below the Volcanic Group. J 
. Phacops-vobertst Beds. 
CARADOCIAN. Calymene Beds. 
‘The Phacops and Calymene beds are remarkably similar in 
lithological characters (dark calcareous shales and impure 
limestones), but the paleontological change is at the top of 
the Calymene beds, and the fauna of the Phacops beds is allied 
to that of the succeeding strata. In addition to other fossils, 
the Ashgillian strata contain graptolites, which have not been 
found, however, in the Ashgill shales. Dicellograptus anceps 
Nich. comes in the Phacops beds, and ranges up into the beds 
above the volcanic group. The Ashgillian beds are, therefore, 
the zone of Dicellograptus anceps. The succession in this 
district is much clearer than in the Lake District, and it is 
suggested that it be adopted as the type sequence for the 
Ashgillian beds of the North of England.’ 
PALLAS’S SAND GROUSE IN YORKSHIRE. 
The following letter from the pen of Mr. Riley Fortune 
appeared in the press a little while ago :—‘ It has been reported 
to the Wild Birds’ Protection Committee of the Yorkshire 
Naturalists’ Union that a flock of between two and three 
hundred Pallas’s sand grouse has been seen in the North 
Riding. The particular locality it is not necessary to specify. 
It is a strange time of the year for these birds to visit our 
country, and suggests that stress of weather or scarcity of 
food has influenced the movement, rather than, as has been 
suggested in connection with previous visits, that they are 
seeking to escape from an overcrowded area prior to the 
breeding season. There can be no mistake in the identification 
of the birds, as the observer who saw them is thoroughly 
acquainted with the species. - In order to prevent the usual 
slaughter which has accompanied previous immigrations of 
this and other species into this county, this letter is written 
to draw the attention of the public to the fact that these birds 
are protected all the year round by special Act of Parliament. 
The Yorkshire Naturalists’ Union Wild Birds’ Protection 
Committee will take immediate action against any infringement 
of the Act of which they can learn, as they are determined to 
do all in their power to prevent the killing of these or any 
other rare birds which visit the county. ‘‘ A word in season ”’ 
may prevent someone “ pleading ignorance ”’ of the Act.’
