INTERNATIONAL BOTANICAL NOMENCLATURE. 



List of British Seed-Plants and Ferns exhibited in the 

 Department of Botany, British Museum (Natural History). 8vo. 

 Pp. 4 + 44. London, 1907 \d. 



The interest of this pamphlet lies not in the fact that it is a list or 

 catalogue of the British herbarium in the British Museum, but that it is 

 a revision of the nomenclature of British plants, in accordance with the 

 rules adopted by the International Botanical Congress at Vienna, 1905. 

 Dr. Rendle and Mr. Britten, who are responsible for the list, deserve our 

 thanks for having produced a very useful little work, which will be 

 welcomed by students of British plants, even though it introduces still 

 further changes in our already much altered plant names. The giving 

 of a full reference to the original description of each species is valuable in 

 a handy list of the kind, as also the correlation of the names used in 

 the three leading handbooks of the British flora : viz., Bentham's 

 "Handbook," Hooker's " Student's Flora," and Babington's "Manual." 



BUTTERFLIES AT HOME AND ABROAD. 



A Natural History of the British Butterflies: their world- 

 wide Variation and Geographical Distribution. A Text- 

 book for Students and Collectors. By J. W. TuTT, F.B.S. Vol. i. 

 London: Elliot Stock, 1905-6. Pp. iv. + 480. Plates xix. Price, is. 



This book may be regarded — so Mr. Tutt tells us in his preface — as 

 vol. viii. of the " Natural History of the British Lepidoptera," vol. iv. of 

 which has been already noticed in the Irish Naturalist (vol. xiii., 

 pp. 160-1). Its publication at the present time has resulted from the 

 accumulation in the author's hands of a large amount of material on the 

 Butterflies, and from the need for a " really good scientific work " on 

 that popular group of insects. The first instalment of this vast amount 

 of material, here offered to the student of insects, will be found an in- 

 valuable mine of information. How rich the material is maybe gathered 

 from the fact that the systematic part of the volume, including 400 

 pages, contains the account of only ten species. On this scale of treat- 

 ment Mr. Tutt will require six or seven volumes in which to deal with 

 all the British butterflies! 



In the first 80 pages of the volume will be found fourteen chapters, 

 lour of which deal with eggs, and nine with larval structure and habits. 

 A single chapter, entitled " General Observations on Butterflies," and 

 restricted to less than two pages, contains all the general information
