monophylla) and a small species of live oak. In the gulches of the 

 mountain side are several winter springs, still running sparingly at 

 this date. The mountain is extremely rough and rocky and trails 

 for pack animals are few. The formation is chiefly granite and 

 immense boulders lie piled one upon another over most of the 

 surface leaving little chance for the smaller plants. The highest 

 ridge is said to be about 7000 feet in altitude, above which extend 

 several barren rocky peaks some distance higher. 



The bulk of the bird list refers to California territory; indeed, 

 only two species — the Vireo and the Verdin — were not taken or 

 seen on California soil, though both doubtless occur as plentifully 

 on the west bank as on the east. Several species found to be 

 common in California and southern Nevada in the immediate 

 vicinity of the Colorado River have not previously been considered 

 as regular summer residents in the vicinity, and I am not aware 

 that the Dwarf Cowbird has been specifically reported from Cali- 

 fornia or Nevada. Thanks are due to Dr. C. Hart Merriam, 

 Chief of the Biological Survey, for permission to publish these notes ► 



Laras delawarensis. Ring-billed Gull. — I examined the head, 

 wings, and tail of a gull of this species wliich had been shot at Ivanpah 

 station a few weeks previous to my \'isit. It was a single bird and when 

 killed was circling over the water tank at the station. 



Pelecanus erythrorhynchos. AYhite Pelican. — Reported as some- 

 times common on the Colorado River at Needles during migrations. The 

 Mohave Indians call the pelican Yak-win-ye-hool'-yah. 



Mergus senator. Red-breasted Merganser.— The sun-dried remains 

 of a full plumaged male found on the desert near the center of Ivanpah 

 Valley. The bird probably perished from want of water. 



Anas platyrhynchos. ^Mallard. — Said by the Mohave Indians to be 

 common, with other ducks in the winter, on the Colorado River. Their 

 name for the Mallard is Ah-nah-mo'. 



Plegadis guarauna. White-faced Glossy Ibis. — ■ A flock of eight 

 seen flying low over the Colorado River at Needles, May 2. 



Ardea herodias treganzai. Treganza Blue Heron. — In the hotel at 

 Goffs is a mounted Blue Heron which was killed some years ago on the dry 

 desert near the station. On the Colorado River several were seen about 

 the little lakes in the bottoms above Needles. 



Nycticorax nycticorax naevius. Black-crowned Night Heron. — At 

 our camp above Needles in the Colorado River bottoms we frequently 

 heard the Night Herons as they passed over in the evening. 



Himantopus mexicanus. Bl.\ck-necked Stilt. — I shot a single bird
