meeting of the Society in April last, was, he believed, referable to Anisolabis 

 tasmanica, Bormans, described in the ' Comptes Rendus' of the Ent. Soc. 

 Belgique, 1880, p. lxviii. 



The Rev. A. E. Eaton made some remarks on the synonymy of the 

 Psychodidce, and stated that since August, 1890, he had identified all of 

 the British species in Mr. Verrall's list, except Sycorax silacea. 



Mr. Gervase F. Mathew, R.N., communicated a paper entitled " The 

 Effect of Change of Climate upon the Emergence of certain species of 

 Lepidoptera." A discussion followed, in which Mr. Stainton, Mr. Barrett, 

 Dr. Sharp, and Mr. M'Lachlan took part. — H. Goss, Hon. Secretary.

An Introduction to the Study of Mammals, Living and Extinct. 

 By W. H. Flower, C.B., F.R.S., and E. Lydekker, B.A., 

 F.G.S. 8vo, pp. i— xvi, 1—763. London: A. & C. Black. 



It was an excellent notion to reprint in one volume the 

 articles on Mammals contributed to the last edition of the 

 ' Encyclopaedia Britannica.' We advocated this course many- 

 years ago, and we are glad to find that time- has since removed 

 the objections which were then urged to its adoption. 



We have now in a handy and amalgamated form a series of 

 very valuable sections on living and extinct Mammalia, with all 

 the original illustrations and some new ones, supplemented by 

 much additional matter, and we are glad to find that the volume 

 contains not only the work of the two authors whose names 

 appear on the title-page, but also the articles contributed to the 

 same Encyclopsedia by Dr. G. E. Dobson, Mr. 0. Thomas, and 

 others. 



The authors, in their * Preface/ have anticipated criticism, on 

 one point at least, by remarking on the difficulty of determining 

 the amount of detail desirable to be introduced to meet ordinary 

 requirements, without rendering the volume too bulky or too 

 costly, and they admit having in many instances described certain 

 little-known species at considerable length, while treating others 

 with much greater brevity. This, we think, is to be regretted. 

 It is the little-known animals that we want to know more about; 

 animals about which we can find nothing in the ordinary text-
