OF THE CANIDA AND URSIDA. 927 
and the second and fifth shorter. The carpal pad is relatively 
larger, the posterior region of the plantar pad is less overgrown 
with hair, and the hairs arising just behind the digital pads are 
exceedingly long and project forwards beneath the pads as far as 
the tip of the long slender claws. 
The rhinariwm is slightly acutely rounded in profile view 
anteriorly ; from the front its upper edge is tolerably evenly 
curved and its inferior border only slightly angled mesially, the 
area below the nostril being moderately deep in front and narrow 
below the slit posteriorly. 
The facial vibrisse are long and normal in position. 
Otocyon megalotis Desin. 
(Text-fig. 8, E, F.) 
In all essential respects the feet of this fox, accorded generic 
‘ank mainly by reason of its abnormal dentition, agree with 
those of Vulpes vulpes and bengalensis, although the third and 
fourth digits are a little shorter. The median lobe of the plantar 
pad is a little more prominent, especially as compared with that 
of V. bengalensis, and its posterior border is emarginate by the 
erowth of hairs as in that species. The carpal pad is very small. 
The rhinariwm is slightly elevated above and rectangularly 
rounded anteriorly in profile view ; seen from the front its upper 
edge is straight with obtusely rounded angles and its lower edge 
is angular, the portion below the nostrils being shallow and very 
narrow laterally and posteriorly below the slit. 
The facial vibrisse ave normal in position and moderately long. 
CONCLUSION. 
Although only a few species of Canidee, compared with the 
numbers known, have been described in the foregoing pages, 
they fortunately represent the main groups of generic or 
subgeneric rank into which the family has been divided.  [t is 
probable therefore, | think, that the extremes of variation in 
the structure of the feet, in the shape of the rhinarium, and the 
disposition of the vibrisse have been observed. 
It does not appear to me to be likely that the broad distinetion 
between Speothos and the rest will be lessened by the examination 
of other species—and probably Lycaon and Cuon, and possibly 
Alopex, will also remain isolated; but it would be rash to assume 
in the present state of our knowledge that the differences in 
foot-structure between the species recorded under Pseudalopex, 
Oerdocyon, Canis, and Vulpes will hold good in all cases when 
the species related to them come to hand for examination. 
That, however, remains to be seen. 
In the meantime, it may be useful to tabulate the results so 
far achieved to show briefly how the species may be grouped, 
and to draw attention to the more salient characters presented 
by the feet. In the following table, however, | have only made
