Acer glabrum. —A small maple occurred widely scattered along 

 creek beds from 7,000 to r 0,000 feet. 



Sambucus. — The elderberry was observed occasionally between 

 the altitudes of 7,500 and 9,000 feet. 



Amelanchier . — The June-berry was seen only near the Coal Kilns, 

 where it formed an extensive thicket about a spring, the bushes 

 attaining a height of ten feet. 



Spirea. — A few bushes seen at 8,500 feet on Hannopee Creek. 



Symphoricarpus . — The snow-berry was an abundant bush from 

 7,000 feet to the summit of the range. 



Artemisia tridentata. — The sage-brush formed a heavy growth m 

 many places and occurred from 6,000 feet to the summit of the 

 range. 



Ceanothus. — A small Buck-thorn, or lilac, occurred sparingly at 

 8,500 to 10,000 feet. 



In the lower part of the Upper Sonoran Zone, and lower, various 

 species of cacti of the genera Opuutia, Ccrcus, and Echinocactus were 

 abundant. The mesquites were common in creek beds up to an 

 altitude of 6,000 feet." 



Wild Rose Spring "is situated at the north end of the Range 

 proper, on the western side, on a broad, open flat, at 4,500 feet. A 

 small stream rises at the spring and -flows a short wav down the 

 canon. The spring and canon are overgrown by rose bushes, willows, 

 Baccharis, etc., and has long been the favorite residence of the Pana- 

 mint Indians. The higher ground near the spring is comparatively 

 level and of a sandy character, with loose rocks scattered through 

 it. The vegetation near the spring is largely creosote, but this soon 

 gives way to an unbroken growth of Colcogync.'" A series of Perog- 

 nathus panamintinus was obtained here, and I presume thev are 

 topotypes, as Perognathus Flat, the type locality of the species, 

 lies between Wild Rose Spring and Emigrant Canon. This Spring 

 appears to be near the northern boundary of Mil pes arsipus, being 

 the most northern point at which the animal was taken.. From Wild 

 Rose Spring, the second ridge of the range was crossed and camp 

 made in Hannopee Canon (which extends directly east from Telescope 

 Peak), at an elevation of about 7,500 feet, near the lower edge of 

 the Pihon Belt, where seven days were passed, and a considerable 

 number of specimens secured. "Hannopee Canon," says Mr. Heller, 

 "drains the whole of the east side of Telescope Peak and contains 

 the largest stream of water in the Panamint Range. Our first camp 

 was situated on the north fork, at about 8,500 feet, and another 

 tarn]) was made in the main canon at about 6,000 feet, where a con-
