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 3Iephitis americana and if. hicolor. 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.— Above 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 on 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 vuliiaris. 

 Head and body about 1 1 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 pinones, the fruit 

 of Finns edulis. We did not observe it west of Mt. Sitgreaves. 



Three specimens were collected, (156;) all lost on the Isthmus.
