but few remains; but these certainly represent two genera. The 
author only describes one species, to which he gives the name of 
Ornithochirus Bunzeli. There are, in all, probably ten genera of 
Dinosaurs and five genera of other groups, making fifteen in all. 
The paper was supplemented by a note by Prof. Suess on the 
geological relations of the beds at Wiener Neustadt to those of the 
Gosau valley, in which he comes to the conclusion that they are 
older than the true Turonian deposits, and especially older than the 
zone of Hippurites cornu vaccnum.

The following communications were read :— 
1. “ Description of a new Species of Coral from the Middle Lias 
of Oxfordshire.” By R. F. Tomes, Esq., F.G.S. 
The species of Coral described in this paper was referred by the 
author to the genus Thamnastrwa and the subgenus Synastrea, 
under the name of Thamnastrea Walfordi, in honour of its dis- 
coverer, Mr. E. A. Walford. The specimen was from the spinatus- 
beds of the Marlstone at Aston-le-Walls, Oxfordshire. Like Tham- 
nastrea Etheridgei, previously described by the author (Q. J. G.S. 
xxxiv. p. 190) from the Middle Lias of Oxfordshire, this species pre- 
sents the same subgeneric characters as 7’. arachnovdes of the Coral 
Rag of Steeple Ashton ; and the author remarks upon the fact that 
the only species known from the English Lias resemble Corallian 
rather than Inferior-Oolite forms. 
2. “ Note on the Occurrence of the Remains of a Cetacean in the 
Lower Oligocene Strata of the Hampshire Basin.” By Prof. J. W. 
Judd, F.R.S., Sec.G.8. With a Note by Prof. H. G. Seeley, F.R.S., 
The author referred to the rarity of remains of marine Mammalia 
in the Lower Tertiaries of Britain, the only recorded species being 
Zeuglodon Wanklyni, Seeley, from the Barton Clay. The single 
specimen in his possession was obtained at Roydon, about a mile 
and a half north of Brockenhurst, where the beds exposed in the 
brickyard consist of sandy clays crowded with marine fossils, and 
resting upon green freshwater clays with abundance of Unio Solandri 
belonging to the Headon series. The author briefly referred to the 
question of the horizon of these deposits, which he regards as 
belonging to the same great marine series as the beds of Brocken- 
hurst and Lyndhurst, which he holds to be Tongrian or Lower 
Oligocene. 
The Cetacean vertebra obtained by Prof. Judd was stated by Prof. 
Seeley to be a caudal vertebra, probably the eighth, but not later 
than the twelfth, of a species belonging or closely related to the
