224 BRITISH BIRDS. [vol. xiu. 



watch on a restricted area, has perhaps added most to our knowledge ; 

 the Black Redstart must rank as a bird of double passage and winter 

 visitor ; the Yellow and Blue-headed Wagtails are regular as migrants 

 in areas where the former, even, does not nest ; and Mr. Forrest has 

 admitted the error he made about the status of the White Wagtail 

 on autumn passage. To have doubted this proved lack of personal 

 knowledge of his area. The author, even now, does not realize the full 

 value of Mr. Jones's observations : this is noticeable in his remarks 

 about Richardson's Skua, a bird familiar to anyone who really knows 

 the northern seas — Liverpool and Carnarvon Bays and the Anglesey 

 coast ;■ — it is often present in considerable numbers. The addition of the 

 Great Skua, about the same time that it was recognized off the Cheshire 

 shores is also interesting. Mr. H. G. Alexander's recognition of the 

 Willow-Tit is a challenge to Welsh observers. Two other most import- 

 ant additions are the Blue-winged Teal and Crane; neither of which 

 showed signs of previous captivity. 



All the more interesting avian notes have appeared in British Birds 

 or are extracted from published books ; there is but little original 

 matter and in some cases this is rather trivial padding. The addition 

 to the lists of mammals and reptiles are not upon firm foundation ; the 

 bird section is the best. On the whole, however, Mr. Forrest has com- 

 pressed into small compass a large amount of useful information, and 

 every possessor of the " Fauna " will need this supplement. — T.A.C.
