summit of the blade of pm. 4 considerably damaged. The two true molars are ■ 
intact, and from their somewhat worn condition indicate the fully adult age of the 
animal to which they belonged. The teeth agree almost precisely with those of the 
Dublin cranium the oidy distinction between the two being a slight difference in the 
form of m. 2 , which is probably only an individual variation. The specimen exhibits 
a very deep depression in the palate between pm. 4 and m. 1 ( not well shown in the 
figure ) ; which is more marked than in existing wolves. The dimensions of the 
specimen are as follows, vis . : —

It will be seen from this table that the carnassials of C. pallipes are on the whole 
shorter than those of C. lupus ; although there is an overlap in this respect between 
the largest of the former and the smallest of the latter. It will also be observed that 
in all the individuals of the former mTT is considerably longer than pm. 4 ; but that 
the proportionate difference diminishes as the teeth become absolutely larger. The 
same may be observed in the case of C. lupus , but still more markedly, so that in one 
case pm. 4 is but very slightly shorter than m. 1. It appears, therefore, that in these 
species as the carnassial teeth increase in absolute size, the increase of the upper 
tooth is greater than that of the lower. In all the individuals of these two species 
of which the measurements are given, the united length of m. 1 and m. 2 is greater 
than that of pm. 4. In C. chanco , however, this excess is very slight, and in C\ laniger 
the latter dimension is the larger of the two. 
In the Siwalik wolf pm. 4 , which is about equal in size to the average of that 
l In this table O. pallipes 1 is the specimen in the writer’s collection, already alluded to ; and C. pallipes 2 the specimen of 
which the measurements are given by Mr. Bose : the dimensions of C. cautleyi 1 are from the specimens figured in plate 
XXXII. of this volume : and C. cautleyi 2 from the Dublin specimens. The other measurements are taken from the table in 
Prof. Huxley’s memoir (p. 279), and have been altered from millimetres to decimals of an inch.
