equal, and their claws reaching to the base of the claws of the third and fourth. There is no 

 indication of any webbing between the toes, which are cleft nearly to the metacarpus and 

 metatarsus. 



The feet of Nasua exhibit considerable differences from those of Procyon lotor, as just described. 

 The claws are considerably larger and stouter. The digits, too, are more united, the skin 

 extending as far as the penultimate joint ; the free portion of the toes, consequently, of much 

 less extent. In the alcoholic specimen there is also a curious elongate papillose condition of 

 the skin immediately under the heel, not observed in Procyon. 



At present there appear to be two pretty well marked species of raccoon in North America 

 the Procyon lotor and P. hernandezii. As the characters of these depend somewhat on different 

 proportions of certain parts of the body in each, I present tables of measurements of skins and 

 skulls which may serve to illustrate their peculiar features. 



Measurements.
