214 THE SCOTTISH NATURALIST 



BOOK NOTICES. 



Report on Scottish Ornithology in 191 2, including Migra- 

 tion. By Leonora Jeffrey Rintoul and Evelyn V. Baxter {Scottish 

 Naturalist Extra Publication, No 2). Edinburgh : Oliver & 

 Boyd. London : Gurney & Jackson. Price is. 6d. net. 



We have pleasure in calling attention to this most useful publication, 

 which should be in the hands of all who are interested in Scottish, 

 or for that matter in British Ornithology. For the second time the 

 Report on this subject takes the form of a separate pamphlet, being 

 No. 2 of the "Scottish Naturalist Extra Publications." The reason 

 for the separate publication of the Report was explained in our pages 

 last year, and we have to repeat that the Misses Rintoul and Baxter 

 have not only drawn up the Report from the voluminous data received 

 a by no means light task but have become financially responsible 

 for it as well. We hope our readers will give their support by 

 purchasing copies. 'The plan of this Report is the same as in the 

 previous one ; the observations for the year being treated of under 

 a dozen headings, e.g., Birds new to Scotland, Uncommon Visitors 

 and Birds new to Faunal Areas, Extension of Breeding Range, 

 Ringing, Migration [summarised under each month], and Notes on 

 Movements of Birds in 191 2. The last section is arranged under 

 species (distinguishing subspecies), and runs to 58 pages. The Report, 

 which this time extends in all to 96 pages 16 more than that for 191 1 

 reflects in a worthy manner the ever-growing activity in the field 

 of Scottish Ornithology. 



A Bibliography of the Tunicata. By John Hopkinson, F.L.S., 

 etc. London : Ray Society, 1913, 8vo, pp. viii + 228. 15s. net. 



This bulky volume, in which the author brings together the titles of 

 papers dealing with Sea Squirts published up to 1910, impresses one 

 heavily with the enormous amount of work which has been expended 

 on these lowest chordata. The titles are given under authors' names 

 arranged alphabetically a system which, if convenient to the librarian, 

 is scarcely so useful to a worker in search of a particular branch 

 of information. But a subject classification would have multiplied 

 manyfold the labour involved. As it is, the author has devoted much 

 time and endless pains to make his compilation perfect, and not the least 

 valuable part of his research has been given to the elucidation of obscure 

 and baffling dates of publication. To the student of the Tunicata the 

 volume will prove of great service, and the general zoologist will find it a 

 more complete guide to his text-book references than the indices of the 

 books themselves. J. R.
