Dr. J. E. Gray on the Skull of Balena marginata. 155 
shorter and broad at the base, gradually tapering to a point in 
front ; and the lower jaw bones are thin, compressed, and high, 
with the upper edge dilated and inflexed the greater part of 
their length, and the lower edge similarly dilated in the front 
part or chin. 
I propose for this animal the name Neobalena; and it may 
be thus characterized :— 
NEOBALANA. 
Skull rather depressed; brain-cavity nearly as long as the 
beak, depressed, much expanded on the sides, with a very 
deep notch on the middle of each side over the condyles of the 
lower jaw, and with a subtriangular crown-plate. The nose 
as broad as the expanded brain-cavity at the base, regularly 
attenuated to a fine point in front, and slightly arched down- 
wards. Lower jaw laminar, compressed, high; the upper 
edge thin, and inflexed the greater part of its length, erect in 
Fig. 1.
