The existence of the Grizzly Bear in the Northern States of Mexico is attested by 
the naturalists of the United-States Boundary Survey?4. The single specimen obtained 
by them in Sonora presented some slight variations in coloration and proportions from 
Californian examples, which induced Professor Baird to describe it as a separate variety 
(horriaeus) ; but they were merely comparative, and may not improbably have been 
individual peculiarities. 
How much further the Grizzly Bear may extend into Mexico I have been quite 
unable to learn. Mr. J. W. Hinchliff was assured at Mazatlan that Bears were very 
numerous in the mountains of the interior*; but he appears to have obtained no 
evidence in confirmation of the report.

Hab. NortH America, from Alaska southwards ?.\—MeExico, Sonora (Dugés *). 
The Black and Cinnamon Bears of North America were separated as varieties by 
Audubon and Bachman; and Professor Baird, in treating of a specimen of the latter 
killed close to our northern boundary, raised it, though with some doubt, to specific 
rank>, It appears now to be certain, however, that the two forms cannot even be 
regarded as distinct races; Mr. Allen observes that their skulls are not in any way 
distinguishable, and that the distinction between the animals “is one of colour only, 
and inconstant as characterizing any particular locality or region” ®. 
According to Dr. Dugés the American Bear is found in the Mexican State of 
Sonora?; but I have not been able to trace it further to the southward.

The existence of Seals on the coasts and islands of Central America was recorded by 
some of the older voyagers. Dampier, in describing “the Alcranes, 5 or 6 low sandy 
Islands, lying in the Lat. of about 23d. North, and distant from the Coast of Jucatan 
about 25 Leagues,” observes, ‘‘ Here are many Seals: they come up to sun themselves 
only on two or three of the Islands, I don’t know whether exactly of the same kind 
with those in colder Climates, but, as I have noted in my former Book, they always
