and lateral ridges are rather indicative of resemblance to [guanodon. 
The dermal armour, however, must not be neglected, as suggesting a 
not improbable and near relationship to Hyleosaurus. The Dino- 
saur from the Gosau beds (Upper Greensand), which Dr. Bunzel refers 
to Seelidosaurus, is closely allied to Acanthopholis, though it cannot 
be included in that genus.

On the Skeleton of Anoplosaurus curtonotus, Seeley, a Dinosaur 
from the Cambridge Greensand, contained in the Woodwardian 
Museum of the Uniwersity of Cambridge. (Plates XXXIV. & 
XXXY.) 
At the close of the year 1872 Mr. Henry Keeping secured for 
the Woodwardian Museum, from one of the phosphatite-washings near 
Reach, an associated series of Dinosaurian bones, which, though in- 
dicating an animal of no large size, makes a considerable addition to 
our knowledge of the Cretaceous modifications of that organic type. 
In all there are about 77 bones or fragments of bones, which may 
be referred to under the following osteological headings :— 
1. Anterior extremity of left ramus of lower jaw. 
2. Five or six centrums of cervical vertebra. 
3. Twelve or thirteen centrums of dorsal vertebra and fragments 
of ribs. 
. Six centrums of sacral vertebre and fragments of sacral ribs. 
. Eight centrums of caudal vertebree. 
. Four neural arches of vertebree, chiefly dorsal. 
. Evidence of both coracoids. 
. Proximal end of scapula. 
. Proximal and distal ends of right humerus. 
10. Proximal and distal ends of left femur; and other fragments, 
among which are metatarsal bones, phalanges, and fragments of the 
left tibia, 
All the specimens are more or less broken and worn; they are 
incrusted with Oysters and Plicatule; but having lain in the sea 
where the phosphates were not abundant, are in a pale state of 
mineralization, and have few adherent masses of phosphate of lime 
upon them. Like the other Cambridge-Greensand fossils which 
have come under my notice, they show no signs of being derivative, 
and appear to me to be of Upper Greensand age. 
The Lower Jaw.—The fragment of jaw (Plate XXXY. fig. 1) is 
22 inches long. It is fractured posteriorly, inferiorly, where the 
inner margin of the bone is thin, and anteriorly, so that it affords 
no evidence of the nature of the symphysial union of the rami other 
than that it was very short and narrow. The jaw becomes less 
deep from behind toward the anterior extremity, as in other Dimo- 
saurs, and teeth were apparently continued almost, if not quite, to 
the anterior end. The alyeolar margin is nearly straight, being but 
very slightly convex externally, and similarly concave internally, 
Ls is compressed from side to side, 2 inch thick posteriorly, and 
5 ch thick anteriorly ; it may have ‘peen vertical, As preserved,
