8, On the discovery of the remains of a gigantic Dinosaur in the Cre- 
taceous of Mew Jersey; by E. D. Corps. (Proc. Acad. Nat, Sci. Philad., 
1866, 275.)—Prof. Cope exibited the remains of a gigantic extinct Dino- 
saur, from the Cretaceous Green Sand of New Jersey. The bones were 
portions of the under jaw with teeth, portions of the seapular arch, in- 
cluding supposed clavicles, two humeri i, left femur, and right tibia and 
fibula, with numerous phalanges, lumbar, sacral and caudal vertebra, and 
numerous other elements in a fragmentary condition. 
The animal was found by the workmen under the direction of J. C, 
Voorhees, superintendent of the West Jersey Marl Company’s pits, about 
two miles 90 ~ as Barnesboro, Gloucester Co.

The discovery of this animal fills. a ees in the Cretaceous fauna, 
revealing the carnivorous enemy of the great herbivorous Hadrosaurus, 
as the Dinodon was related to the Trachodon of the Nebraska beds; and 
the Megalosaurus to the Iguanodon of the European Wealden and Oolite. 
n size this creature equalled the Megalosaurus Bucklandii, and with 
it and Dinodon, honabistited the most formidable type of rapacious terres- 
trial vertebrates of which we have any knowledge. In its dentition and

mbling in its proximal regions more nearly that of the Iguanodon, 
indicated ee probable pai of other equally ineoeetadi a Re 
and its pertaining to another genus. For this and the species the name 
of Lelaps aquilunguis was proposed.

Exploration of the “ Bad Lands” or “ Mauvaises Terres” of the 
Upper Missouri region; by Dr. F. V. Haypen eee Mate has just 
gust 3d, with an escort of five soldiers, a ee team, one sph a 
guide and Indian interpreter, and an Indian as hg ip inall. The 
party went up the Niobrara, north side, as far as Bapid r up 
that stream to its 3 ad, crossed over the divide to ‘ie ppeien fork of 
White river, passed along the south side of White river to White Earth 
creek, about 100 miles north of Fort Laramie, at which aa they were 
nearly south of the Bad Lands. From thence they tra the whole 
of the Bad Lands and returned on the old Fort Pine ad, thence on the 
south side of the Missouri to Fort Randall, having been absent fifty-two 
days. Dr. Hayden has made very extensive collections of fossils, including 
about fifty turtles, two of them of the largest size, nearly or quite perfect. 
The distance travelled on the way out from Fort Randall and beak was 
650 miles, and the specimens gee were transported by land 
that. wild country for more than 300 miles. We hope soon to give a 
full account of the results of the aleuke, —— must be of great im- 
portance to geological science, coming from one so able and experienced . vig 
in a and so familiar with the whole: Une Missouri region.
