is reached, and we have the first portion of the account of 

 Helix pomatia, besides the full accounts of three other snails. 

 This part contains also a coloured plate showing figures of 

 those delicate shells belonging to the genus Hyalinia and 

 others. These figures are both so truthful and beautiful that 

 they seem beyond praise. 



Besides giving all the details of a species, with maps of its 

 distribution, Mr. Taylor treats of the fossil and Nearctic 

 allies, and gives portraits of both the older and the living 

 conchologists. The book is therefore not only of high 

 scientific value, but contains also much of what the late Mr. 

 Stainton was wont to term readable matter. 



The handy volume, " Plant Galls of Great Britain," by the 

 late E. T. Connold, contains 354 excellent illustrations, 

 mostly of galls that occur in Britain on various plants. We 

 constantly find galls in the course of our rambles, and this 

 book will enable us to identify many of them and learn 

 something of the lives of their inhabitants. This volume is 

 a small edition of the late author's two other works on galls, 

 and contains the galls of the oak and those of other plants, 

 arranged for easy reference. 



That monumental work, "A Natural History of the British 

 Butterflies," by Mr. Tutt, though so thoroughly worked out, 

 has almost reached the end of volume iii. For a work of 

 this kind the progress is rapid. The present volume treats 

 of five very interesting species of "Blues" and their allies. 

 One of the great features of this work is that the author 

 and his collaborators have, whenever possible, worked out 

 the life-histories of each species anew and much more fully 

 than has ever before been attempted. The structure of the 

 perfect insect and of the insect in its earlier stages has been 

 carefully examined, whilst the literature dealing with the 

 subject, of which there is a vast amount, has all been 

 digested. Thus, the author has arrived at a standpoint from 

 which he could take a comprehensive view of each species 

 and present the same to his readers. 



The volume by Mr. F. N. Pierce, "The Genitalia of the 

 British Noctuidae," containing descriptions and 350 figures of 

 the ancillary appendages of the Noctuidce, constitutes a new 

 departure in entomological literature, and will, no doubt, 

 be an incentive to many entomologists who have not yet 

 done so, to study the morphology of these organs. This 

 study, so ably carried on by Mr. Pierce for over twenty years, 

 provides a further set of factors of great use in the determina- 

 tion of species.
