of Mr. Barrett's book, it is more than compensated by the 

 issue of this great work. Commenced some seven years 

 since, four volumes, dealing in the most comprehensive and 

 up-to-date manner with various sections of the moths, have 

 been issued, and we are anxiously awaiting the early publica- 

 tion of vol. v. But, in the meantime, Mr. Tutt has hit upon 

 the happy idea of issuing the section dealing with the 

 butterflies in parts, which have been appearing at frequent 

 intervals during the year. The butterflies are treated in the 

 same comprehensive manner as the moths, and it would be 

 difficult to find any point in regard to any of the species 

 treated of that is not fully set forth. 



"The Butterflies of the British Isles," by Richard South, 

 is one of the " Wayside and Woodland Series," published 

 by Frederick Warne & Co., the special object of the series 

 being to supply full and accurate details of the subject 

 treated, in a form convenient to carry in one's pocket when 

 on a country ramble. The book is fully illustrated with 

 coloured and plain plates, and never before has such a vast 

 fund of accurate and useful information been compressed 

 between the two covers of a book of its size. I am glad to 

 know that there is a good probability of the British moths 

 being treated in a similar manner, and by the same author. 



x\ll three of these works, it will be noted, treat of virtually 

 the same subject, but so diverse are their methods that, I 

 doubt not, there is ample room for all of them. 



I should like also to refer to a couple of other works : 



"The British Woodlice," by W. Mark Webb and Charles 

 Sillem, is a monograph of the terrestrial Isopod Crustacea 

 known to occur in Britain. Each species is fully described, 

 and figured on a large scale, and the book should prove an 

 incentive to the study of this hitherto terribly neglected 

 group. 



"The Mammals of Great Britain and Ireland," by J. G. 

 Millais, has been completed, and is, perhaps, the most sump- 

 tuous work on the subject yet published. 



In his Presidential Address, delivered at our last Annual 

 Meeting, Mr. Hugh Main touched upon the question of 

 melanism in Lepidoptera ('Proceedings,' 1905 — 1906, p. 65). 

 For this reason I venture to call attention to the following 

 important papers, referring to the subject, that have appeared 

 during the year, viz. : " Melanism in Yorkshire Lepidoptera," 

 by G. T. Porritt, read before the Zoological Section of the 

 British Association, at their meeting held in York, in August 

 last (" Report of the Brit. Assoc, Sect. D.," York, 1906) ; a
