have felt it our duty to refer, seriously affect the authors' work. 

 This lias been well done. The history of each species is a 

 thoroughly exhaustive and conscientious piece of work, and the 

 important task of sifting the records of rarities has been done 

 with caution and sound judgment. The notes under each 

 species connected with its migrations are also e.xtremely useful, 

 but the subject of migration as a whole, as observed in 

 Yorkshire, has been shirked, and we are only given an extract 

 from Mr. Eagle Clarke's British Association "Digest." 



The work contains much information hitherto unpublished, 

 and amongst the records referring to species already dealt with, 

 before the publication of this work, in the series of articles now 

 appearing in these pages on the "Additions since 1899," the 

 following may be mentioned, while others will be incorporated 

 in their correct places in future instalments of the above- 

 mentioned articles. White s Thrush has occurred five times in 

 Yorkshire, and not four, as stated antea, p. 53 ; the Bock Thrush 

 is admitted on the evidence of one seen at Whitby in 1852, a 

 record probably rejected by Mr. Saunders; the authenticity 

 of the specimen of the White-spotted Bluethroat obtained at 

 Scarborough in April, 1876, is fully established ; a Bed-spotted 

 Bluethroat was identified at close range at Easington on 

 September lOtli, 1901 ; a valuable account is given of the range 

 of the Nightingale in Yorkshire, from which it appears that it is 

 not so rare in the lowlands as stated antea, p. 55, except in the 

 western side of the county where it is unknown. The authors 

 are not always up to date : there are now four records for the 

 Orphean Warbler, not two, as stated on page 69, and at least 

 double the number of Barred Warhlers stated on page 75 as 

 having occurred in the British Isles, and about fourteen of the 

 Icierine Warbler instead of eight. The record of one of the 

 latter seen in September, 1897, near Easington, Holderness, by 

 Messrs. Clarke and Laidlaw appears to be new ; four Black- 

 bellied Dippers (seldom satisfactorily identified) are recorded ; 

 the Coal-Tit, although recognized as an insular form of the 

 continental species, is yet called Parus ater ; the Crested Tit, 

 mentioned by Mr. Saunders (III. Man., 2nd. Ed., p. Ill), as 

 having been shot near Keighley, is here considered not authentic: 

 on page 124 is an apparently good record of the nesting of a 

 pair of White Wagtails at Cleveland, in 1899 ; there are several 

 records of occurrences of Blue-headed Wagtails. 



In conclusion we may offer our hearty congratulations to the 

 authors for having completed a most valuable and highly 

 necessary work. A few small criticisms on the production of the 

 book may be useful. It is nicely printed and the letterpress 

 is upon suitable paper, but the illustrations are printed upon 

 heavily "loaded" paper, which as is well known crumbles 

 away in a few years, and had the illustrations been of more
