trum is ten inches in transverse diameter; with others it is more 
depressed and more deeply bi-concave than the corresponding 
vertebra of C. supremus. The femur of this species is very thick, 
its length is fifty inches and the diameter fourteen i inches. 
ditional remains of Camarasaurus supremus include a femur 
six feet, and a scapula five and a half feet in length. The pos- 
terior dorsal vertebra exceed in dimensions those of any known 
saurian, equaling those of the right whale. The centra measure 
sixteen inches in transverse diameter. 
Mount Lepanon Fismes IN Daxota.—Many years ago Dr. 
Hayden obtained some fossil fishes from the Cretaceous No. 3 
of Dakota. They have been recently examined by Professor 
Cope, who, describes them in the late number of the Bulletin 
of the United States Geological Survey of the Territories. 
He refers them to the genera Triæenaspis g. n., Leptotrachelus 
Mark, /chihyotringa g. n., Spaniodon Pict., and Sardinius Mark. 
The first, second and third genera belong to the Dercetide, and 
Leptotrachelus has been found in Syria and Westphalia. /chthyo- 
tinga is allied to Dercetis of Westphalia, and 7rienaspts to Pela- 
sabi of the same region. Spaniodon is a well-known Leb- 
non type and Sardinius is abundant in Westphalia. This deter- 
EE De adds evidence to that already in our possession, showing 
the wide distribution of types in the Northern Hemisphere during 
past time. 
CRETACEOUS FisHes oF EncLanp.—E. Tully Newton of the 
British Geological Survey, has recently discovered the Kansas 
genera Portheus and Ichthyodectes in the chalk of Kent, and finds 
several species of both. 
Ciepsyprops IN Texas. — Professor Cope has recently ob- 
= Texas. This discovery confirms the reference of the Clepsydrops 
= shales of Illinois to that formation or the Permian, in opposition 
to the view at first maintained ig Professor Bradley that they are 
a member of the coal measure 
THE GENUS E EET eye R. Lydekker has recently 
described the dentition of this genus, ea was discovered by 
Falconer in the Sivalik formation of India. He regards it as a 
bunodont Artiodactyle allied in some pom to Hippopotamus. 
He finds it to be very peculiar in that the premolar teeth are of 
relatively enormous size, although simple in their form. The 
characters of the genus resemble those of Elotherium. 
THE AFFINITIES OF THE DinosAuRIA.—Professor Owen recently 
described an interesting Dinosaurian under the name of Osmosaurus 
armatus. At the close of the article he makes some remarks on 
the structural relationships of the order. He thinks that the 
_ pubic bone is directed forwards, not backwards, as asserted by 
_ Huxley. The bird-like structure of the tibio-tarsal articulation, —
