NOTICES OF NEW BOOKS. 91 



collections made during this expedition, which, we read, " have no 

 claim to completeness, since they were not part of my special ob- 

 ject ; but new facts relating to such forms as Nautilus, Peripatus, 

 Amphioxus, Ctenoplana, Balanoglossus, &c, cannot fail to pos- 

 sess a peculiar interest." 



The opening memoir is by Dr. Willey on a species of Peri- 

 patus which he obtained in the island of New Britain. One 

 interesting fact is here brought out, that whereas formerly, and 

 based on our then knowledge, it was a conclusion that the 

 species of Peripatus could be arranged in three groups in 

 accordance with their geographical ranges — viz. Neotropical, 

 Australasian, and Ethiopian — the new species constitutes the 

 type of a new group which may be designated Melanesian. The 

 biological strength of this paper is beyond the aim of our pages; 

 but it is not by new species that this journey will be alone remem- 

 bered. Some animals were procured which, though known to 

 science, were unrepresented in our National collection, such as the 

 rare marine Snake Aipysurus annulatus, and Prof. Studer's Echi- 

 noderm Astropyga elastica. The work, as we announced in these 

 pages (1898, p. 376), will comprise five or six parts ; and the first 

 and second have as yet only just reached our hands. Consequently, 

 at present, a detailed review is impossible. Already a good staff 

 of naturalists have commenced to contribute ; and the names of 

 Arthur Willey, Paul Mayer, G. A. Boulenger, K. J. Pocock, 

 D. Sharp, Sydney J. Hickson, F. Jeffrey Bell, F. P. Bedford, 

 Arthur E. Shipley, J. Stanley Gardiner, F. G. Beddard, and 

 Isa L. Hiles are guarantees of special work by specialists. The 

 work is beautifully illustrated. 



Wild Life at Home : How to Study and Photograph it. By 

 R. Kearton, F.Z.S. Cassell & Co., Ltd. 



The well-deserved success of the author's last work, * With 

 Nature and a Camera,' with its beautiful illustrations of animal 

 life, has induced a wide-spread interest in the method of photo- 

 graphing glimpses of nature. In response to many enquiries, as we 

 are told, the present book is intended to clear the way for the in- 

 creasing number of those who wish rather to possess realistic pho- 

 tographs than the actual birds or nests. A "technical instructor"
