in the same way as it does in the genera Moniligastcr and Hi/odrilus, 

 which belong to other families. Mr Iizuka suggests that this differ- 

 ence is due rather to ignorance of the true structure of Pontodrilus 

 than to any divergence in the case of the present species. The last 

 paper, by Mr M. Namiye, describes the indigenous snake Achalinus 

 spinalis. 



BIBLIOGRAPHY 



The Geological Survey of Belgium, having with some success pub- 

 lished voL i. of Bibliographia Geologica, specifying all works and 

 papers on geological subjects that appeared during 1896, now proposes 

 to issue a retrospective series. The first volume will comprise the 

 titles of all geological publications in the library of the Belgian 

 Survey, arranged according to their subject-matter on the plan of the 

 decimal classification. Authors who wish to see their works quoted 

 in so useful a catalogue will, it is hoped, send copies to the library in 

 question. They may address the Director, Dr M. Mourlon, 2 Paie 

 Laterale. Brussels. 



New Serial 



We welcome an Italian rival, Rivista di scienza biologiche, edited by 

 Dr Enrico Morselli, professor of psychiatry at Genoa University. 

 Subscriptions are received by Dr P. Celesia, 46 Via Assarotti, Genoa. 



The Rev. H. X. Hutchinson (Author of "Extinct Monsters") is at 

 present making a large collection of photographs from life of native 

 races of all countries, including Pacific Islands, to illustrate a popular 

 work which he will publish next year in twenty-four sixpenny parts, 

 with Messrs Hutchinson & Co., of 34 Paternoster Row, E.C. For 

 this purpose he requires good, strong, clear photos of men, women and 

 children — some in groups, others as single figures. Silver prints will 

 be preferred. Iieaders of Natural Science who have such photographs 

 are requested to communicate with Mr Hutchinson, through the 

 publishers, with a view to purchase.
