The most prominent difference between the specimens
was in the width of th e ujrper jaw in front o f th e notch,
ju s t over the commencement o f th e teeth-series ; b u t I
could not find any other character in connexion with it.
There is also a slight difference in th e form o f the palate ;
in a, the central ridge is narrow and rounded above behind
; in b, it is broad, flat, sharp-edged, an d very deeply
concave on the sides, under the edges, b u t th e different
specimens vary in this particular. In d and g the hindei-
p a n of the palate, near the entrance of the inner nostrils,
is sharply keeled ; and in a the two ridges are rounded.
I am by no means certain th a t with a larger series of
skulls iu a perfect condition, and with the animals they b e longed
to, it might not prove th a t there are more than one
species amongst these skulls.
In all these skulls the interraaxillaries are seen below,
forming a slender, elongated, triangular space in th e front
of the palate, and in some the vomer is also more or less
seen in the middle o f the p alate ; but the absence and p resence
of tins bone in the palate, which Mr. Owen appears
to regard as important in the distinction of species (see
Biilish Fossils,’ p. ), is o f very little consequence, at
least in this species.
In the British Museum there is a foetus, figured with its
longue in .detail at (Tab. 26.), whiph probably belongs to
« u s species ; it formed p a rt o f the- collection o f Sir Hans
bloane. •
I t differs from the foetus ofLage/iorhy/ichus acutus in the
nose, being more produced (nearly 4 the length o f th e dis-
tauce from the end o f the nose lo th e eye), it has seven
mack rigid bristles on each side, the two front, rather
Ihe largest, are on the side o f the upper j>art of the nose,
and the five hinder forming a descending line nearly parallel
to the groove which separates the beak. T h e tongue is convex
on the sides, with a ra th e r narrow flat space on the
h in d e r p a rt separate from th e u nder sides by a sharp e n tire
edge, the front is ra th e r dilated, sharp-edged and ob scurely
crenaled.
