and of a different species has lately^ 
been seen as far as Lake Erie, and 
lat. 42. One was shot by the 
Seneca Indians, to whom it was to- 
tally unknown, another was killed 
in the Alleghany mountainsof Penn- 
sylvania, and an account given in 
the papers. These animals were 
totally distinct from the common 
Jaguar; they must have been 
wanderers from New Mexico or the 
Oregon mountains, and belong pro- 
bably to a new species which I pro- 
pose to call Fells dorsalis , owing to 
the black band on the back. There 
are several other species of Jaguars 
in South America, little known or 
not well distinguished. 
Specific characters , Felis Dor- 
salis, Dorsal Jaguar. Of a grey 
colour, neck fallow, a black line or 
band ail along the middle of the 
back, two rows of ringed spots on 
each side, black above, brown below. 
Total length 10 feet including the 
tail, body 6§* tail S|. Very differ- 
ent from Felis pardalis by size four 
times larger, neek and back, &c. 
14. On the JSTorth American Cou - 
' guars . By C. S. R. 
The unspotted Tygers, or Lions 
without mane, of America have been 
called Couguars from the Guarani 
name, or Puma the Peruvian name. 
There are several varieties of them 
in North and South America, not 
well known as yet; in South 
America they are red or black, 
which perhaps indicate different 
species. In North America, fallow 
or grey. All these are called 
Felis concolor by the zoologists and 
deemed identic. This may be 
doubted; we know too little of these 
animals to decide; as they are be- 
coming scarce it;*is needful to pre- 
serve the knowledge of those yet 
extant. The following are on re- 
cord or have fallen under my notice. 
They are called Panther, Fainter , 
and Catamount in the United 
States. They winter with us. 
1. Var. Yellowish, 8-| feet long. 
In Carolina. Dr. Mease. 
2. Var. Entirely grey^ Green 
mountains. Dr. Morse. 
3. Var. Fallow; outside of the 
ears, Feet and end of the tail black. 
Body four feet, tail nearly three. 
Seen in Kentucky. 
4. Var. Back nearly black, sides 
dark reddish bro wn, feet black, body 
six feet, tail three feet, legs very 
short, only one foot long. In New 
Hampshire. Dr. Moose. 
5. Var. Differ from the last by 
body five and a half feet, tail two 
and a half feet, feet twenty to twen- 
ty-two inches long, called Pennsyl- 
vania Couguar by Buffon. Alle- 
ghany mountains. These two last 
appear to deviate much from the 
species. 
* The Couguars being spread from 
Canada to Chili, or 90 degrees of 
latitude, must vary in their fur. 
Every traveller gives a different 
account of them, or calls their fur 
by a different name, black, brown, 
red, rusty, fallow, sallow, yellow, 
grey, &c. They may yet belong 
all to a single species; but these 
varieties or deviations must be 
noticed, as they are in man, the 
dog, the sheep, and other deviating 
animals. 
15. Extracts from A Second Series 
of Zoological Letters written to 
Baron Cuvier of Paris, by Prof 
Rafinesque in 1831. 
Extracts from letter 1, March, 
1831. — I sent in 1821 to Paris, a 
memoir on fifteen Triiobites of 
North America, and published in 
Lexington the new 6r. Jsoctomesa 
of that family, which Dr. Dekay 
has since erroneously called Octo» 
merisj there is a G. Octomeris , 
already among shells; my Sp. was 
however different from his, being 
emarginated behind, and one of the 
largest Trilobite known, being nine 
inches long. It was preserved in 
the Cabinet of the University. 
There are also some very small 
Triiobites nearly like the Ento- 
mostraceous; such is my Anopsites
