in the same way as it does in the genera Moniligaster and Ilyodrilus, 
which belong to other families. Mr lizuka 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 Bebliographia 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 lbrary 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 Rue 
Latérale, 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. N. 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. Readers of Natwral Science who have such photographs 
are requested to communicate with Mr Hutchinson, through the 
publishers, with a view to purchase.
