608 PROF. W. H. FLOWER ON FOUR SPECIMENS _ [Dec. 9, 
process; the second and third have also moderately long capitular 
processes ; the fourth has none; the fifteenth rib is slender and 
twisted, but nearly as long as the penultimate. The sternum con- 
sists of a broader anterior portion, 21" from side to side, and a 
narrow posterior prolongation, turned somewhat to the right side, 
82" long; the whole length from before backwards is 17". The 
anterior border is very thin, notched, and evidently incompletely 
ossified ; about 1! behind it is an oval foramen, 1" in length, situated 
in the mesial line. The hyoid (basihyal and thyro-hyal ankylosed) 
is 33! across. The scapula is 253" in height, and 46" in breadth. 
The humerus 173" long ; the radius 283"; the ulna 323", or with- 
out the olecranon 273". The length of the cranium is 14! 6", the 
greatest breadth 6! 4", The length of the rostrum 10', The breadth 
of the middle of the rostrum 30"; the breadth of the maxillary at 
this point 83", of the premaxillary 52; the premaxillary projects 
9" beyond the maxillary. The length of the lower jaw is 13! 6”. 
2. The next animal (a male) was stranded near Falmouth in Au- 
gust 1863. The skeleton was prepared by Mr. Gerrard, jun., at 
whose establishment I examined it in April 1864. It is now in the 
Alexandra Park. It is (or was when I last saw it) quite perfect, 
with the exception of one or two of the terminal phalanges. All 
the epiphyses of the vertebree are completely united, so that the 
animal must have been fully adult. The skeleton as articulated 
measures in a straight line 66!, of which the skull occupies 15! 6". 
The various dimensions of the cranium and mandible are given in 
P. Z. S. 1864, p. 411*. 
There are sixty-one vertebre ; but the last is elongated and con- 
stricted in the middle, as if it really consisted of two united. Of 
these, seven are cervical, fifteen thoracic, fourteen lumbar, and twenty- 
five or twenty-six (according as the last is reckoned as one or two) 
caudal. The second cervical has immense, expanded, backward- 
directed transverse processes, with a large perforation at the proxi- 
mal end. The second, third, fourth, and fifth have the upper and 
lower processes united so as to form rings. The sixth has a long 
upper process; but the lower one is a mere tubercle, larger on one 
side than the other. In the seventh the lower process is entirely 
absent. The extreme width between the ends of the transverse pro- 
cesses of the different cervical vertebrz is as follows :—First 26", 
second 43", third 34", fourth 354", fifth 353", sixth 34”, seventh 
334". The foramen in the transverse process of the second cervical 
vertebra is 63! broad, and 4! high; the corresponding foramen in 
the third vertebra is 8" broad, and 64" high; in the fourth 84" 
broad, and 6" high. 
The chevron bones appear to be all present. There are eighteen ; 
the first and the last three have not united in the middle line. The 
first is placed at the hinder end of the body of the thirty-seventh 
vertebra. The vertical perforations through the base of the trans- 
verse processes commence in the eighth caudal vertebra. 
* The atlas, axis, and fifth cervical vertebra of this specimen are figured by 
Dr. Gray in ‘Cat. of Seals and Whales in Brit. Mus.’ 1866, p. 145.
