all the 1ST earctic and Pal sear ctic regions as far as the Atlas Moun- 
tains. the Indo-Chinese sub-region in the mountains, and to 
Hainan and 'Formosa ; Helarctos, the Malay or sun-bear (1 
species) confined to the Indo-Malayan sub-region ; Melursus or 
Prochilus, the honey-bear (1 species), confined to the first and 
second Oriental sub-regions, over which it ranges from the 
Ganges to Ceylon ; and Tremarctos , the spectacled bear — com- 
monly known as Ursus ornatus — which is isolated in the Andes 
of Peru and Cliili, and forms a distinct group. 
Fossil Ursidce . — Two bears ( Ursus spdceus and U. prisons) 
closely allied to living species, abound in the Post-tertiary de- 
posits of Europe ; and others of the same age are found in North 
America, as well as an extinct genus, Ardodus. 
Ursus arvernersis is found in the Pliocene formation of Prance, 
and the extinct genus Leptarchus in that of North America. 
Several species of Amphicyon, which appears to be an ances- 
tral form of this family, are found in the Miocene deposits of 
Europe and N. India; while Ursus also occurs in the Siwalik 
Hills and Nerbudda deposits.

The Otariidse, or Eared Seals, comprehending the sea-bears and 
sea-lions, are confined to the temperate and cold shores of the 
North Pacific, and to similar climates in the Southern Hemisphere, 
where the larger proportion of the species are found. They are 
entirely absent from the North Atlantic shores. Mr. J. A. Allen, 
in his recent discussion of this family (Bull. Harvard Museum) 
divides them into the following genera : — 
Otaria (1 species), Temperate South America, from Chili to 
La Plata ; Callorhinus (1 species), Behring’s Straits and Kams- 
chatka ; Ardocephalus (3 species), temperate regions of the
