regarding the physical features of the rocks in which the fossils are 
found. ‘The essay supplies several more items of information on this 
subject which should be of interest to paleontologists.

1. Mexican Grorocy.—The latest batch of Mexican geology was 
received in London in the middle of July. It consisted of the 
Boletin and the Parergones del Instituto Geologico de Mexico from 
1918 to 1916. Of first importance is the Boletin for 1914, containing 
G. R. Wieland’s ‘‘ La Flora Liasica de la Mixteca Alta’’, with its 
atlas (1916) of fifty fine quarto plates. The Parergones to 
hand includes the whole of vol. vy (1918-16), and is largely 
occupied with seismological records from 1911 onwards. In part iv 
(1918) are a variety of analyses of rocks and waters; part v (1913) 
deals with the water-supply of various Mexican cities; part 1x (1914) 
is a catalogue of the Mexican rocks preserved at the Institute ; ; and 
part x (1916) contains more water-supply papers. 
2. Inpran Gerotogy.—Mr. C. de P. Cotter has produced a Contents 
and Index to the Memoirs of the Geological Survey of India, vols. xxi— 
xxxv (1884-1911), for which the cordial thanks of all geologists are 
tendered to him. 
3. New Guinean Geotoey.—In Reports on the Collections made 
by the British Ornithologists’ Union Expedition and the Wollaston 
Expedition in Dutch New Guinea, 1910-13 (2 vols. 4to, 1916 
(Francis Edwards), price £10 10s.), vol. 11, Report 20, 1916, 
Mr. R. B. Newton reviews previous work on the island and then 
describes the Foraminiferal Tertiary Limestones. These limestones 
are full of ZLepidocycline, the large forms (ZL. murrayana and 
LL insule-natalis) and the smal! (Z. swmatrensis), as in the Christmas 
Island rocks, and Mr. Newton regards them as indicative of 
the later part of the Aquitanian age. An excellent plate of oat 
micrographic sections by Green accompanies the report.

‘‘New Bennettitean Cones from the British Cretaceous.” By 
M. C. Stopes, D.Sc. Communicated by Dr. A. Strahan, F.R.S. 
The present paper describes two new types of well- preserved 
fructifications of Bennettites in Britain. One is that of an entirely 
new species from the Gault; the other is from a Lower Greensand 
specimen, diagnosed from externals by Carruthers, but not, hitherto 
described.
