of the two true molars on the other, form a very marked angle with one another, 
and are consequently both 
oblique to the median line 
of the palate ; in the fossil, 
although pm. 4 , is still set 
obliquely to the same line, 
the outer border of the two 
true molars of the left side 
runs almost exactly parallel 
to the median line of the 
palate, causing the angle 
between the two lines to be 
considerably more open. 1 In 
all other existing members 
of the Ganince , with the 
exception of Otocyoh , the 
position of these teeth is the 
same as in C. littoralis. In Otocyon , 2 however, the outer border of the true molars 
runs parallel to the median palatine axis, while pm. 4 is also set parallel to the same 
line, though somewhat internally to the outer line of the molars. It thus appears 
that in the characters of the hinder cheek-teeth the fossil skull presents certain 
characters intermediate between the smaller alopecoids and Otocyon , although in the 
proportionate size of these teeth to the skull it is considerably nearer the former. 
On the right side of the specimen the alopecoid characters are more clearly marked. 
In regard to the earlier premolars, the table of measurements will show that 
these are much smaller in’ the fossil than in C. bengalensis , and (as may be seen by 
comparing the figure of the former with that of C. littoralis) are placed closer together ; — 
so close in fact that pm. 2 and pm, 3 overlap. In all other species of Ganis the earlier 
premolars are elongated and separated by distinct intervals ; but in Otocyon in size 
and position they are very similar to the fossil, although there is no overlap, and the 
antero-posterior shortening is still more pronounced. The skull itself in its short 
and wide form is nearer to Ganis littoralis and Otocyon than to G. bengalensis. On its 
superior surface it agrees with those forms and the other small alopecoids by the 
enclosure of a lyrate ‘ sagittal area ’ 3 by the temporal ridges. Posteriorly these 
ridges unite to form a small sagittal crest, as in G. bengalensis , and G. corsac ; but the 
middle part of the sagittal area is wider and more lyrate, and it edges more cord- 
like than in those species 4 : being in fact in this respect intermediate between those 
1 These characters are not quite so strongly marked on the right side. 2 See Huxley, op. cit., fig. 13, p. 260. 
3 In the weaker- jawed alopecoids, the temporal ridges, which are separate in all young Canince, never unite throughout 
their length to form a sagittal crest ; and the area enclosed by them is termed hy Prof. Huxley the sagittal area. 
4 The excellent figures of the skulls of these forms given hy Prof. Huxley may be compared with the figure of the fossil.
