NOTICES OF BOOKS. 



The Tailless Batrachians of Europe. Part ii. By G. A. Boulenger, 

 F.R.S. London: The Ray Society, 1898. 



The present year will be memorable in the popularisation of 

 Zoology, if only for the appearance of this splendid and inspiring 

 treatise, now complete. The part before us, paged serially with its 

 fellow, deals on the same lines as that with the Bufonidae, Hylidae, 

 and Ranidae, and there are given in illustrations fourteen plates, four 

 maps, and forty-four text figures, all of which are worthy the text and 

 the preceding part which has everywhere been hailed with acclamation. 

 Concerning the general merits of the work, we have nothing to retract 

 from our wholly laudatory comments upon the first part. All that is 

 important in taxonomy and distribution, and of interest concerning 

 breeding habit and racial varieties, has, up to the requirements of the 

 work, been collected together and presented to the reader in a form well 

 calculated to arouse his enthusiam and interest in the familiar though 

 much despised Frogs and Toads. And for the English student the 

 book has an especial value, in being based upon the matchless collec- 

 tions preserved in our own Natural History Museums, a full list of 

 which is appended. It teems with originality, and one of its most 

 conspicuous features is the recognition of observations on habit and 

 geographical limitation made in the field of the self-trained nature- 

 loving traveller, who, in our present severely academic days, is apt to be 

 considered unscientific, and thereby discouraged in what the perusal of the 

 pages of this book amply proves to be good and useful work. It is for 

 such as these that the book and its companion volume are primarily 

 intended and most heartily do we congratulate both the author and 

 the Ray Society upon their completion. In publishing them they 

 have set up a high standard, and we would reiterate the hope that they 

 will with as little delay as possible follow up this their new venture, 

 and provide correspondingly for the treatment of the Tailed Batrachians, 

 which in many points of popular interest and scientific value even 

 excel their tailless allies.
