710 MR. G.KREFFT ON A NEW SPECIES OF EUPHYSETES. [Nov. 28, 
bedded here and there in the less hard, darker, and porous bone. 
The lower jaw also much resembles that of Gray’s Whale; but the 
sides are not so. thin; the teeth are longer, stronger, and curved 
backwards, instead of standing out sideways. The rami in Gray’s 
Cetacean are not much thicker than parcbment. The teeth of the 
present species are thirteen in number in each ramus, the first three 
being almost straight, the next four gently curved backwards, and 
the last six almost hook-like. ‘The seventh tooth, which is about 
half broken, is apparently the longest and strongest of the set. 
If people only knew how valuable complete specimens of animals 
are to the naturalist, they would certainly not mutilate them as they 
often do; for had it not been for Mr. Skinner, who secured this 
Whale, all the teeth would have been knocked out to be made into 
* charms”’ for watch-chains. 
The spinal column consists of the anchylosed cervicals, thirteen 
dorsal, nine lumbar, and twenty-six caudal vertebrae, the first ten 
of which have V-bones attached tothem. All the vertebree are con- 
siderably larger and much more porous than those of LZ. grayit, 
the neurapophyses being very broad at the top. The total width 
of the atlas is 6 inches, its greatest vertical height 53 inches, and 
length or thickness 2} inches; this bone is so spongy that in hold- 
ing it against the light one .can see clear through the pores of the 
neurapophysis as through a sieve. There are thirteen ribs on each 
side, differing but slightly in length, as the following table will 
show :—

The respective weight of the two sides is—Right side, 5 lbs. 9 ozs. ; 
Left side, 5 lbs. 8 0zs. Not one of these ribs is grooved like the 
eighth, ninth, and tenth in Gray’s Whale. In shape they differ 
both from Catodon and from Luphysetes grayii, being rather rounder 
at the upper half, and becoming flat towards the end; the outside 
edges are strongly marked with a series of knobs or protuberances, 
which in the ninth and tenth are strongest. The sixth, seventh, 
eighth, and ninth ribs suddenly diminish in width about 6 inches 
from the end, after producing a sharp protruding ridge.
