Specimens of this wolf were collected in the San Francisco mountains. Their fur was softer, 
and the skull broader than those of the Missouri. 
MEPHITIS —Skunk. 
A skunk (No. 158) was obtained at camp 104, Pueblo creek, New Mexico, intermediate in 
size between the common Mephitis cimericana and M. bicolor. Its general color was black, with 
a white line on each side, white forehead and white tip to the tail. It was lost with the other 
alcoholic specimens on the Isthmus.

Sp. Ch.—A bove finely grizzled bluish gray and black; a broad dorsal stripe of pure chestnut from shoulders to tail; under 
parts and feet white ; a distinct dark line ou each side of the belly. Tail very full and bushy, as long as the body; pure white 
beneath, above mixed black and white. Ears with long tufts springing from the superior border of the ear, as in Sciurus vulgaris. 
Head and body about 11 inches long. 
This beautiful squirrel was very common in the San Francisco range of mountains, living 
among the tall pines that here abound, and finding its chief subsistence in the pihones, the fruit 
of Finns edulis. We did not observe it west of Mt. Sitgreaves. 
Three specimens were collected, (156;) all lost on the Isthmus.
