262 Fossil Bones found in Vermont. .. 
Of the limbs, the two scapula, one humerus, and the two fore- 
arm bones on one side, and the ulna of the other side, are secured ; 
all the other bones of the fins are missing. Fig. 13 represents 
the recovered bones of the left fin, in their places. The height 
of thé scapula is seven inches, the length of the humerus five, and 
of the forearm four inches. 
here are several of the recovered bones, whose places are not 
yet ascertained. Some of these may be appendages to the hyoid 
bone and others may belong to a rudimentary pelvis. Professor 
Agassiz who has manifested, as already stated, a deep interest 1n 
these fossils, has kindly consented to give them that further care- 
ful investigation, and illustration, which their importance demands, 
and for which he is most ably qualified ; I have, therefore, placed 
them in his hands for that purpose. 
The following measurements of the head, are all that I have 
been able to make, which admit of direct comparison with Cu- 
vier’s measurements of the head of the Beluga, J). leucas. (Oss. 
Foss., v, p. 392. ) ;

From these measurements it might be inferred that the foss¢ 
and the D. leucas were identical in species, as well as in genus; 
.but, at the same time, so many points of disagreement have been 
observed, as to render it highly probable that they are specifically 
different. In the number of teeth, they differ, as expressed below.

They also differ much in the relative width of the maxillary 
and intermaxillary bones, as developed on the upper side of the 
snout, the intermaxillary being wider than the maxillary in Cu- 
vier’s figure, while in the fossil, the latter is twice the width of the 
former. The lines of the face appear also to be straighter, and the 
coronal process less elevated, making the upper portion of the 
head flatter in the foss#/ than in the D. leucas. 
That this fossil cetacean belongs to the genus Delphinus of 
Linneus, and to Lacepede’s subgenus, Delphinapterus, 1 have 
little doubt; but, as already stated, it is highly probable that it 
belongs to a different species from Gmelin’s Jeucas. would, 
therefore, propose Delphinus Vermontanus for its provisional 
specific name, until its identity with the D. leucas, or some other 
known species, shall be established. 
The locality, where these fossil bones were found, is situa- 
ted a little more than one mile to the eastward of lake Chan 
and 60 feet above the meau level of the lake, as ascertained
