260 Fossil Bones found in Vermont. 
Of the vertebre I have secured forty-one, of which four are 
cervical, eleven dorsal, ten lumbar and sixteen caudal. Three of 
the cervical vertebra, the first, fifth and sixth, are evidently miss- 
ing, which, with those obtained, would make seven, the usua 
number. These vertebre are all free, not being soldered together 
as in the common dolphin and some other cetaceans. Fig. 5 
represents the third cervical vertebra. 
Of the dorsal vertebrae, the second and twelfth are missing, 
making their whole number thirteen. Fig. 6 represents the sev- 
enth dorsal vertebra—a, as seen from behind—2, as seen laterally. 
‘Two of the lumbar vertebrae, the sixth and twelfth, are miss- 
ing, making twelve in the whole. Fig. 7 represents the seventh 
lumbar vertebra. They-all have the same general form, but the 
lateral winged processes are more decayed and broken in some of 
them than in the one represented. ‘The eleventh and seventeenth 
caudal vertebree are missing, and perhaps a nineteenth and twen- 
tieth, making their probable whole number twenty. Fig. 8 rep- 
resents the fourth caudal vertebra. The form of those towards 
the extremity of the tail may be seen in fig. 1. 
rom these statements it appears, that the whole number of 
vertebre in the skeleton was fifty-two. Eleven of these are 
surfaces on the under sides of the caudal vertebree, indicate five 
chevron bones, of which I have all but one, only the fourth being 
one. Fig. 9 represents the second chevron bone. 
The total length of the vertebral column, (due allowance being 
made for the eleven missing vertebrae, but none for intervertebral 
cartilages, ) is just ten feet, or one hundred and twenty inches. 
Of this Jength the cervical vertebrae occupy eight inches, the 
dorsal thirty-six, the lumbar forty-two, and the caudal thirty-four. 
The lumbar vertebre are largest, having an average length of 
about four inches and a diameter of three inches. The total 
length of the animal, including the head and caudal fin, must 
have been at least thirteen feet. The hyoid bone, fig. 10, and 
the sternum, fig. 11, are both very large and strong in proportion 
to the size of the skeleton. The former measures eight and a 
half inches in a straight line from point to point, and the latter is 
fifteen inches long, from three to seven inches wide, and on an 
average nearly one inch thick. ‘There are four articulating cavi- 
ties for ribs on each side 
‘he ribs are considerably decayed and much broken. The 
longest rib, in one piece, measures just twenty-four inches along 
the curve. The ribs which form the anterior pair are very strong, 
and unbroken, and consist, on each side, of two parts of solid bone 
as represented in fig. 12.
