6. A new Theriodont Reptile—A new Theriodont from the 
Upper Permian sandstone near Orenburg in southeastern Russia 
has been described by . Twelvetrees, in a paper read — 
before the Geological Society of London. The beds rest on 
limestone which has the fossils of the Zechstein. Besides 
remains of Saurians and Labyrinthodonts, there are Calamites, 
Lepidodendron, Conifers and a Unio. The specimen is hero 
ently the pai part of the ‘left mandibular ramus, with t 
crowns of a canine, an incisor, and ten of the molars. It is 
closely lade: % the genus Rhopa lodon ; but there are marked 
differences, and the author proposes to call it Cliorhizodon

7. A new species of Iguanodon, I. Preswitchii.—The remains 
of this na species of Iguanodon are from the Kimmeridge clay, 
three miles west of Oxford. The skeleton was probably almost 
entire, but as the clay had been mostly removed before attention 
was directed to it many bones are lost The iscovery is the 
subject of a paper before the Geological Society of London, April 
14th, by Prof. J. Prestwich. Prof. Prestwich’s paper was fol- 
lowed by another by J. W. Hulke, Esq., describing the bones in 
Soe No. 48 giving the species the ‘above name.— Quart. J. Geol.

with Supplements for 1874-1876. Edited by Wm. WurrrakER,

8vo. London, 1880. (Taylor & Francis.)}—This volume of the 
Record, like its predecessors, will be found of great value to 
geologists. The author has had a dozen or more able coadjutors 
in the preparation of the volume. Its several subdivisions are 
Petrology ; Mineralogy ; Paleontology ; and Maps and Sections. 
The volume would be still more welcome if it could be issued 
nearer to the year of which it is a ohatord, We find in the pref-
