Case. Shelf. Specimen. 
88 e 2 a similar but smaller jaw with more slender 
teeth. It shows the maxillary and the na¬ 
sal bones behind. From Tewkesbury near 
Gloucester. 
e 3 anterior part of the upper jaw of a short-nosed 
Ichthyosaur with thin alveolar border and 
teeth in situ, conical and apparently smooth. 
The palate is flattened and covered with 
vascular perforations. From Weston near 
Bath. 
e 4 anterior part of the snout of a long-nosed 
Ichthyosaurus, a little compressed, reaching 
back to show the maxillary bone on the 
right side, but the nasal bones do not come 
so far forward. The supra-alveolar and 
infra-alveolar grooves in this species are 
broken up into a number of elongated 
foramina. From near Lichfield.

1 the eye, 3 inches in diameter, of an Ichthyo¬ 
saurus from Whitby. The sclerotic plates 
which defend the eye are thin. They appear 
to consist of two series, one around the cir¬ 
cumference, and a more elongated series which 
defends the front of the eye, and overlaps 
these behind. From this junction radiating 
impressed lines descend towards the unde¬ 
fended central part of the eye. Several of 
the front plates have come away, and show 
casts of their under sides. 
2 a compressed left humerus, showing the outer 
side. 
3 femur, probably left. The ends are vascular, 
and the flattened proximal end unlike the 
rounded condyloid end of specimens in the 
Cambridge Greensand. 
4 a crushed specimen of a small humerus from
