Mr. Mathews will doubtless wish us to emphasize his 
regrouping, which has the coloration of the female as 
a distinctive feature.

On the conclusion of this most useful piece of work, for 
which all British ornithologists must feel grateful to the 
authors, it is our pleasant duty to congratulate them on 
its completeness and accuracy. We have been carefully 
through the pages, and find little to suggest in the way of 
alteration, should a second impression be called for. We do 
not like the abbreviation 44 s ” for “ shire,” as Banffs for 
Banffshire, especially as it is not used consistently. The 
omission of 44 Co ” in many Irish records would possibly 
have been an equal saving in printing ; but this is a small 
matter. A very important point is the collection of records 
from newspapers, such as 4 The Field/ and from small 
local periodicals ; here workers will be saved an enormous 
amount of trouble in hunting through the annual files. 
It is to be hoped that all readers will send a note to the 
authors of any omission ; as a supplement, if not a new 
edition, is sure to be the outcome of this comprehensive 
work. So far we have noticed no such omissions.
