the earlier stages of many of the species, that has been con- 

 densed into the available space is truly wonderful. Like the 

 companion volume on the " Butterflies," it supplies a long- 

 felt want, and should do much to popularise a systematic 

 study of the British Lepidoptera. The advent of further 

 volumes, completing the moths, will be awaited with in- 

 terest. 



" Some Moths and Butterflies and their Eggs," by A. E. 

 Tonge, one of " Gowan's Nature Books," was published to- 

 wards the latter part of the year, and is a very remarkable 

 little volume. It was, I believe, in 1899 tnat Mr. F. Noad 

 Clark, who had for some time taken a keen interest in photo- 

 micrography, exhibited at some of our meetings, among other 

 subjects, several photographs of eggs of Lepidoptera. I am 

 inclined to think that this may have been the incentive ; at 

 any rate, soon after this it was apparent, from the frequent 

 exhibits with which we were favoured, that Mr. Tonge was 

 doing good work in this direction, the outcome of which is the 

 present little volume. It contains remarkably well-executed 

 reproductions of photographs of the eggs of some fifty-nine 

 species, all to the one scale of magnification of 10 diameters, 

 thus admitting of a proper comparison. Each is accompanied 

 by an equally good life-size figure of the perfect insect, in 

 many cases both the male and female being given, and a few 

 pages of explanatory letterpress are added at the end of the 

 book, not the least remarkable part about which is its price, viz. 

 sixpence. Considering how little is generally known about 

 the eggs of even the commonest species of Lepidoptera, Mr. 

 Tonge's little book may be regarded as a most useful instal- 

 ment of a much larger and more comprehensive one that we 

 all hope is to follow later on. 



" A Monograph of the Land and Freshwater Mollusca of 

 the British Isles," by John W. Taylor. The concluding 

 part of Vol. II, bringing the work to the end of the Slugs, 

 was issued early in the year. This book is to the concho- 

 logist what Mr. Tutt's is to the lepidopterist, and should be 

 known to all who take an interest in our slugs and snails. 



"The Birds of Kent," by W. J. Davis. The district here 

 dealt with is so intimately connected with the Society's work 

 that the book should appeal to all our ornithologists. 



" Wild Bees, Wasps, and Ants, and other Stinging 

 Insects," by Edward Saunders. I cannot omit to mention 

 this useful little book on what is, perhaps, the most interest- 

 ing portion of the British Hymenoptera. Although written 

 in an attractive manner, it is needless to add that it is
