154 Dr. J. B. S. Jackson's Dissections of a 
The length was 71 feet; color dusky black on the back, 
white on the belly, and lead-colored on the sides ; a dusky line, 
from one to two inches in width, commenced a little above 
the eyes, and, passing along the sides, was lost in the lead color 
within 18 or 20 inches of the tail, and another, much less dis- 
tinct, ran parallel to this. Very exact measurements were also 
given of the position and dimensions of the external parts. 
'The animal had just been harpooned, and seemed to be quite 
new to the fishermen. 
The fœtus must have been mature, or very nearly so, being 
38 inches, or nearly half the length of the mother. Accord- 
ing to Mr. Owen, the cetacea, in general, are remarkable for 
the large size of the fœtus at birth. It had Sir William Jar- 
dine's characteristics of a true dolphin, the “ convex forehead 
and the snout in form of a beak, distinguished from the fore- 
head by a marked furrow;" in form, moreover, it pretty 
nearly resembled the Delph. delphis, L., as figured in the 
Naturalist’s Library, though it will be shown to differ in 
structure from that species, if, indeed, it is always the same 
species that is described under that name. The back was of 
a dark bluish gray, and the belly nearly a salmon color, but 
this last may originally have been white, as the same change 
color was observed in the D. globiceps ; no longitudinal stripes, 
as in the mother, but some very indistinct, broad, transverse 
stripes were seen towards the back.  'The teeth had not yet 
appeared. Since the dissection the animal has been stuffed, 
and the specimen is now in the Boston Museum. 
As to the number of vertebrx, there were 7 cervical, 14 
dorsal, and 55 posterior to these. In the Dauphin ordinair? 
(by which is understood the Ð. delphis, L.) there are 
by G. Cuvier to be 14 dorsal, and 52 posterior to these 
(Anat. Comp. i. 103,) though in tlie Oss. Fossiles (v. 303) 
‘he says the dorsal are 13, and the whole number, without the 
cervical, 60, leaving 47 only posterior to the dorsal; ^ 
Cuvier (Cet. p. 140) quotes this last. Lesson (Cet. P: - 
says there are 13 dorsal and 53 lumbar in the n 
i,
