unworn^ although most resemhling the others of the same collection, differs in having the true 

 molars still larger. The last upper molar is shaped more like that of T. lahradoria, but it 

 has three lines of tubercles on the crown nearly parallel with each other. This tooth is of

to the distance between these molars 



themselves. The skull is narrower and shorter behind ; the symphysis of the lower jaw shorter, 

 &c. There is no mark to indicate whether this specimeri came from Mataraoras ; from a widely 

 remote locality there would be little hesitation on the part of any naturalist in making of it a 

 distinct species.

** We found the raccoon quite common at various points on our road as far west as Janos, in the State of Chihuahua, but we 

 did not observe it after Jeaving the country adjicent to that village. 



" It prefers the vicinity of running streams where the bushes are ihick, or where there are hollow trees in which it may make 

 its bed. Although eminently nocturnal in its habits it sometimes comes out during the day in the desert places in search of food, 

 especially when it has young. When pursued it takes immediately to the water, swimming with great rapidii-y and ease. 



" We saw them often along the San Pedro river and other streams of Texas in Noverabrr, along the Rio Grande in December, 

 and very often along the Corralitas river in March and April. When there has offered no opportunity for its immediate escape 

 into the water or impenetrable bushes, we have seen it throw itself back in a state of defence, showing its teeth in a threatening 



manner, but never heard it utter any cry. 



" It is called Tejon by the Mexicans of the regions in which we have observed it, and its flesh is highly esteemed by them as 



an article of food," — (C. B. Kennerly.) 



According to Dr. Berlandiere the babits of this species are precisely similar to those of the 



common raccoon.

22. PROCTON HERNANDEZII, var. MEXICANA, St, Hilaire (p. 215.)— Sonora Raccoon.

A single skin was brought from Espia, Sonora, by the Boundary Commission, which agrees 

 perfectly with the figure and description of St. Hilaire in the Voyage de la Venus, based upon 

 a specimen collected at Mazatlan. These localities are quite in the same zoological province, 

 although somewhat distant. The illustrious author of the mammalian portion of the report of 



r 



the Venus is quite satisfied that the specimen examined by him differs in nothing from the 

 true P. loior except in the intensity of coloration. 



The size of the animal is about that of the average of F. lotor. The fur is quite as long as 



y 



P. lotor, and appreciably softer, in this respect differing somewhat from the description of St, 

 Hilaire. The feet appear to be rather slender, and longer than in P. lotor. They are scantily 

 haired and naked in patches on some of the phalanges. The tail is about half as long as the 

 head and body, or perhaps longer ; it is fully furred with long appressed hairs, and tapers 

 gently from the base to the tip, which is somewhat truncate. 



The colors of this animal are similar in pattern to those of the F. lotor^ but the tints show 



considerable differen.ce.
