MAMMALIA — CARNIVORA.

caught by Townsend at Columbia River, is about V longer, and has a 
white line under the belly ; to this belongs Richardson’s Sc. canadensis. 
2. Sc. Breweri ; also with 44 teeth ; glittering ash-grey ; black above, 
brownish beneath ; hands slender ; tail flat, broad, and hairy ; nasal fossae 
situate at the sides instead of on the upper surface of the snout, as in 
Sc. aquaticus ; body 6" ; tail, without hair, 1" ; with hair, 1" 5"' ; 
breadth of hand 4'"; of tail 4'" : in Ohio and several of the Northern 
States. 3. Sc. argentatus, Bachm. ; like the following species, only 
36 teeth ; hair of the back, from the roots upwards, furnished with 
narrow dark blue and white rings to near the points, where a broader 
grey white ring exists, with such a short broWn point, that the clear 
colour on the upper surface is still visible,^ ‘and presents a fair silvery 
appearance ; on the under side the hairs are lead coloured, with a whitish 
and light brown pointed ring standing on end; nasal fossas on upper 
surface of snout ; body 7 " ; tail V ' ; breadth of hand 10'" : from Michi- 
gan. 4. Sc. latimanus, Bachm. ; bigger than Sc. aquaticus ; hair 
longer, looser, and compact, without the same shining glossy appearance, 
dark grey with dark brown points ; teeth and hands almost double the 
size of Sc. aquaticus; tail naked; body 6" 8'"; tail 1" 7 '"; breadth 
of hand 10'" : from Mexico and Texas. According to this, the animal 
described by me (Schreb. Suppl. ii. s. 104) would belong to Sc. latimanus. 
5. Sc. aquaticus, Linn. ; only 5 or 5J" long ; colour, although occasion- 
ally varying, far brighter than in Sc. Townsendii. The young have only 
30 teeth till after the first year, when they get 36. 
CARNIVORA. 
Ursina.— The reporter has taken considerable pains, to show 
that the specific identity of the Cavern Bears with the Brown 
Land Bears, as asserted by Blainville, is untenable. 
As my treatise from the Miin. gel. Anzeig. (1842, n. 130-132) has 
been already reviewed in these pages (1843, p. 24), it is superfluous to 
enter farther upon it. Procyon psora is described by Gray in the Ann. 
of Nat. Hist. X. p. 261. Yellowish -brown and grey, grisled ; face, 
temples, side of neck, chest, belly and sides of body, dirty yellow ; fore- 
head, cheeks under the eyes, each side of the throat an^ back of the 
ears, blackish-brown ; fur rather long, dark brown ; longer hairs yellow- 
white, those of the back, head, and shoulders brown tipped ; tail short, 
perhaps destroyed ? body 27" ; tail 3" ? From California.
