REVIEWS. 175 



indeed nothing of importance to be gleaned from the book 

 by the student of migration. 



With regard to the occurrence of continental forms and 

 their important bearing upon migrational movements, Mr. 

 Evans is much behind the times. Since he calls the Marsh- 

 Tit Parus dresseri we may presume that he recognizes that 

 the British form is distinct from Parus p. palustris, and this 

 being so, there is no reason why he should not recognize the 

 distinctions of many other British forms. He does not even 

 mention the existence of the Continental Song-Thrush, Robin, 

 and Goldcrest, all of which must have occurred in this region. 

 He recognizes that the British Great Spotted Woodpecker 

 is distinct from the Scandinavian, but he dismisses the question 

 of " passing visitors " without giving any details or saying 

 whether he has examined any of them or not ! The import- 

 ance of modern methods of close work seems to be only just 

 dawning on some of our ornithologists, and that Mr. Evans 

 has fallen back from the point reached in recent avifaunas 

 can only be regretted by those who look at the future rather 

 than the past. 



In conclusion, we must say a word as to the excellence of 

 the production of this volume, which is in the same good 

 style as the previous ones, although it seems a pity, on the 

 score of uniformity, that a different kind of paper should have 

 been used. The series of plates from excellent photographs 

 by Mr. W. Norrie, gives one an admirable idea of the region 

 and its bird-haunts, although some of the prints are rather 

 lacking in firmness : the map is everything that could be 

 desired. H.F.W. 



Report on the Immigrations of Summer Residents in the Spring 

 of 1910 .' also Notes 07i the Migratory Movements and 

 Records received from Lighthouses and Light-vessels during 

 the Autumn of 1909. By the Committee appointed by 

 the British Ornithologists' Club. (Forming Vol. XXVIII. 

 Bull. B.O.C.). 21 Maps. Witherby & Co. 6s. 



This is the sixth annual Report of the Committee, and is 

 in the same form as previous issues, except that the observa- 

 tions on " unscheduled " birds and the autumn records have 

 in many cases been condensed and connected. This has 

 resulted not only in a saving of space, but has made these 

 parts of the Report much more interesting and valuable, the 

 autumn records being especially so. The arrival of migrants 

 in the spring of 1910 appears to have been fairly normal, 

 though it is noted that a few species were unusually late, and 

 notably the Spotted Flycatcher, " the main body of which
