Remarks. — The present stibspecies is the raccoon of the Pacific 

 Northwest coastal and Cascade Range regions, extending in small 

 numbers into the interior along the Colinnbia River Valley to north- 

 eastern Washington. Like the regional representatives of other 

 groups of mammals it is characterized b}^ dark coloration. Compared 

 with P. I. lotor of the eastern United States, which is also dark in 

 color, the upper parts in pacificus are more heavily overlaid with black, 

 the light subterminal bands of the longer hairs and the light rings of 

 the tail are grayer, less buffy or yellowish, the top of the head is 

 blacker, and the mask is more uniformly black and contiiuious across 

 the face. P. I. pacificus intergrades with P. I. psora in southwestern 

 Oregon and northwestern California, and with P. I. excelsus east of the 

 Cascade Motmtains in Washington and Oregon. Procyon proteus 

 Brass was assigned to the raccoon of the west coast from Ptiget Sotmd 

 to the Cascade Mountains, which is within the range of typical P. I. 

 pacificus. The name is also preoccupied by Procyon proteus Allen, 

 applied to a crab-eating raccoon in South America.
