Within the limits of the orders these tufts are present in the 
primitive genera, but more or fewer of them may be lost in the 
more specialised types. This fact, coupled with their prevalence 
in widely different types, points to the arrangement of the 
vibrisse above indicated being exceedingly primitive. The 
different modifications of the vibrisse met with in various orders 
were briefly pointed out. 
A second paper by Mr. Pocock “ On the Feet and other 
External Features of the Canide and Urside,” based like the last 
upon work done in the Society’s Prosectorium, dealt with the 
rhinaria, the facial vibrisse, and the pads and interdigital integu- 
ment of the feet in many of the genera of Canidez and all the 
admitted genera of Urside. In connection with the Canide the 
most interesting results were the discovery of evidence, supplied 
by the feet, of kinship between Cuon and Lycaon, and between 
Otocyon and Vulpes. On the other hand, two of the South 
American fox-like dogs Cerdocyon microtis and Bendalopes: gracilis 
differ widely from each other in the structure of the feet, and 
equally widely from Vulpes and Otocyon. The most aberrant of 
all the dogs in the matter of foot-structure is Speothos (Icticyon), 
which is unique in having the digital pads of the third and 
fourth toes of both front and hind feet united, and in having the 
pollex of the front foot set low down adjacent to the postero- 
internal angle of the main or plantar pad. These differences 
seem to justify the division of the Canide into the two sub- 
families Speothoine and Canine. 
In the Urside four well-marked genera are characterised by 
the structure of the feet, namely, Zhalarctos for maritimus, Ursus 
for arctos and its allies horribilis and americanus, Tremarctos for 
thibetanus, japonicus, ornatus, and malayanus, and Melursus tor 
ursinus. Melursus differs from the rest in having all the digital 
pads united almost to their distal ends. Tremarctos differs from 
Ursus in haying the area behind the main or plantar pad of the 
fore foot quite naked, instead of thickly hairy as in Ursus and 
Thalarctos, and Thalarctos differs from Ursus in having the 
plantar pads wide and short and the area of the sole behind the 
plantar pad of the posterior foot covered with hair except for 
a small lozenge-shaped pad towards its outer border. From 
Tremarctos, malayanus may be eliminated as Helarctos by the 
structure of the rhinarium. All the generic names adopted in 
the paper had been previously proposed, mainly upon cranial and 
dental characters; but the evidence from this source is so un- 
satisfactory that there has been no agreement amongst zoologists 
in their recognition.
