340 NORTH AMERICAN FAUNA. [No. 7. 



Pinus lambertiana. 



Common ou the west slope of the Sierra Nevada in a well-marked 

 belt, the vertical breadth of which along the East Fork of Kaweah 

 River was determined by Mr. Bailey to be aboiit 360 meters (1,200 

 feet), or from 1,830 to 2,160 meters (6,000 to 7,200 feet) in altitude. 

 Mr. Bailey found it common at Trout Meadows, and thence along the 

 upper Kern Biver to above Soda Springs. 



Pinus flexilis. 



In California this species was found on the Panamint Mountains 

 above an altitude of about 3,050 meters (10,000 feet), and on the High 

 Sierra, where it ranges from 2,830 to 3,050 meters (9,300 to 10,000 feet). 

 In Nevada it was found on Charleston Peak by Mr. Coville and Mr. 

 Palmer. 



Abies magnifLca. 



Common on the High Sierra. Mr. Bailey informs me that he ob- 

 served it on the west slope near Mineral King at an altitude of 2,230 

 meters (7,450 feet), and thence up to about 3,090 meters (10,300 feet), 

 where it nearly reaches timber-line. 



Abies concolor. 



Common on the High Sierra. On the west slope Mr. Bailey found it 

 between the altitudes of 1,830 and 2,160 meters (6,000 to 7,200 feet) 

 on the East Fork of Kaweah Biver, and up to 2,300 meters (7,700 feet) 

 on Kern River. 



Pseudotsuga macrocarpa. 



This species of spruce occurs in gulches on the west side of Cajon 

 Pass at an altitude of 670 meters (2,200 feet) and upwards, and was 

 found also on the south side of the Sierra Liebre along the upper val- 

 ley of Peru Creek, just below Alamo ranch. Cajon Pass is the type 

 locality of this species. 



Sequoia gigantea. 



Sequoia gigantea forms a conspicuous but narrow and interrupted belt 

 on the west slope of the Sierra Nevada. Mr. Bailey informs me that 

 along the East Fork of Kaweah River he found it between the altitudes 

 of 1,830 to 2,000 meters (6,000 to 6,600 feet), on a very gradual slope, so 

 that the actual breadth of the forest was about 5 miles. 



Libocedrus decurrens. 



Mr. Bailey found Libocedrus decurrens common on the west slope of 

 the Sierra Nevada, along the East Fork of Kaweah River, from 1,830 to 

 2,160 meters (6,000 to 7,200 feet) altitude, and along the North Fork of 

 Kern River up to the cliffs above Soda Springs. 



Juniperus californica. 



The typical form occurs on the coastal slope of the Great Divide in 

 California, sometimes ranging over a short distance ou the Great Basin 

 side, as along the north base of the San Bernardino Mountains.
