The Woodwardian Museum contains a part of a jaw of Squalodon , 
evidently from a nodule seam of the Calcareous Sandstone (found 
by Scilla circ. 1670). The Sand Bed and Calcareous Sandstone have 
furnished remains of more than one species of Delphinusy and large¬ 
sized Cetacean vertebrae are found in neai’ly all the beds, especially 
the Sand Bed. Ualitherium has been obtained from the Sand Bed, 
Marl Bed, Calcareous Sandstone, Lower Limestone, and (?) Upper 
Limestone. 
One specimen of Ichthyosaurus gauclensis, Hulke, has been 
furnished by the Calcareous Sandstone; the same has also fur¬ 
nished Melitosaurus champsoicles, Crococlilus gauclensis , and Sterrodus 
melitensis. Myliohates toliapicus and allied species have come from 
all the deposits except the Upper Limestone ; Otohcites subconversus 
from the Sand Bed and Marl. The Squalidce are abundant from all 
the deposits except the first. There are ten species, belonging to the 
following genera— Oarcharodon , Carcharias , Oxyrhina, Hemipristis , 
Corax , Odontaspis, Lanina. Remains of Notidanus, Platcix, and 
Diodon have also been found. 
2. “ Dinosauria of the Cambridge Greensand.” Parts I.-YII. 
By Prof. H. G. Seeley, F.L.S., P.G.S. 
The author stated that this paper was founded upon the collection 
of more than 500 Dinosaurian bones preserved in the Woodwardian 
Museum, for the opportunity of studying which he was indebted to 
the kindness of Prof. T. McKenny Hughes. He described the con¬ 
ditions under which the specimens occur, and accounted for the 
apparently worn state of the bones as the results of exposure to the 
air, and subsequent maceration. 
I. “Note on the axis of a Diuosaur from the Cambridge Green¬ 
sand.” This bone was said to be very similar to the axis from 
the Wealden previously described by the author (Q. J. G. S. xxxi. 
p. 461), but differed in the neural arch being supported on pedicels 
of the centrum, in both articulations for the rib being on the 
centrum, in the compressed form of the odontoid process, and in 
the subhexagonal form of the oblique posterior articular surface of 
the centrum. There is no indication of a wedge-bone beneath the 
anterior articulation. The condition of the axis in other Dinosaurs, 
such as Zanclodon, was indicated, and reasons given for regarding 
the structure of the bone as a modification of the Crocodilian 
type. 
II. “ On the vertebral characters of Acanthopholis horridus, Hux¬ 
ley, from the base of the Chalk-Marl near Folkestone.” The author 
stated that only dorsal and caudal vertebrae of Acanthopholis are at 
present known. The dorsal vertebrae have the visceral surface 
well rounded, the articular ends subovate, and the centrums 
laterally compressed. The early caudal vertebrae are deep, with 
strong compressed transverse processes, zygapophyses directed well 
forward, and the neural spine directed upward and backward. The
