FROM THE CAPE OF GOOD HOPE, 191 
second molar, m 2, projecting at an interval of 2 millims. from the 
first, presents the same dimensions: the transverse diameter given 
by this better-preserved tooth-fang is 10 millims. The third molar, 
at an interval of 3 millims., has diameters of 11 millims. and 9 
millims. 
After this the molar intervals vary from 3 millims. to 6 millims, 
The elliptical section of the tooth-root is preserved with very little 
yariation from the diameters of the third molar. Remains of eleven 
of these small subequal molars are shown in the portion of upper jaw 
figured in fig. 1, Pl. XI. 
The crowns of these teeth, like those of the incisors, would be 
broader than the exposed roots, and probably occupied space equal 
to the intervals left between those roots ; but, with this assumption, 
the molars are smaller than the incisors, as is the case in Lycosawrus 
pardalis*. 
The number of the molars, supposing the whole to have been pre- 
served in the maxillary fragment described, would be very nearly 
that in the small Theriodont Galesaurus +; and, as the hind fracture 
of the fossil has crossed the eleventh molar, it may well have been 
succeeded by a twelfth, as in Galesaurus, if not by more, as seems 
to haye been the case in Gorgonops, from the proportional length of 
the maxillary of G. torvus, Ow. 
I took advantage of the hind fracture of the maxillary fossil under 
description to get a clearer view of the mode of implantation of 
what seemed to be the terminal half of the root of the eleventh molar, 
It ended, like the first incisor, in an obtuse point, where the pulp- 
cavity was obliterated. No trace of a successional germ or its nidus 
was exhibited in this section (Pl. XI. fig. 5). 
The next more easily recognizable fossil was the anterior end of 
the left ramus of a lower jaw (PI. XI. fig. 6). The rough sym- 
physial articular surface is 4 inches in vertical, 23 inches in 
transverse diameter; but part of the upper border has been worn 
away. The length of the fragment is 7 inches, the height 44, the 
thickness behind the symphysis 24 inches. The outer surface is 
convex and pretty even, with some small, scattered, vascular canals ; 
the inner surface is impressed by a splenial groove, 8 lines in 
breadth, but rapidly contracting where it enters and is lost in the 
symphysial surface. The alveolar border (a, a) about 2 inches in 
breadth, had been subject to abrasion, and showed but feeble indi- 
cations of teeth or sockets. 
Of this border I had the section made which is the subject of 
fig. 6, when the following parts were demonstrated. 
The foremost tooth, 21, was too partially and obscurely repre- 
sented for description. 
The next tooth (7 2) presented, in section, an oval figure, with 
the great end outwards, 21 millims. in long diameter, 15 millims. in 
greatest breadth, with a pulp-cavity (ib. p) of similar form measuring 
10 millims. by 7 millims. This tooth was situated about 14 inch 
from the fore end of the jaw, and 10 millims. from the first incisor,
