the genus, as will be seen by reading p. 21G ; while 

 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 tliis most useful piece of work, for 

 which ail 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 " s " for " shire." as Banffs foi- 

 Banffshire, especially as it is not used consistently. The 

 omission of "Co" in many Irish records would [)()ssibly 

 have been an equal saving in printing ; but this is a small 

 nuitter. A very important point is the collection of records 

 from newspapers, such as '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 compiehensive 

 work. So far we have noticed no such omissions.
