464 bulletin: museum of comparative zoology. 



the Chuisaya Steppe, 12 versts (=8 miles) south of Kosh-Agatch. 

 This was a flat desert of 7,300 feet altitude with very little vegetation, 

 except for a few scrub willows and dwarf thorn bushes growing along 

 the banks of the streams — the Tchegan-Burgazi River and tribu- 

 taries. 



The third stop was made at Topucha where specimens were gathered 

 from August 5 to August 10 inclusive. This place is at an altitude 

 of 6,875 feet, in heavy forest, largely coniferous. It rained hard 

 most of the time the party was camped here, and was very cold and 

 damp, apparently the normal weather conditions of the region. 



Mr. Hollister informs me that the party secured specimens of most 

 of the birds that were seen, the exceptions being large wary species 

 such as the Lammergeyer which was often seen. A falcon (perhaps 

 Hierofalco altaicus Menzbier) was observed on several occasions, 

 always at a distance, and Dr. Lyman once, when hunting sheep, 

 started from among the rocks, one individual of Tetraogallus altaicus. 



In identifying the 52 forms enumerated in the following list, I have 

 had for comparison some material from the U. S. National Museum 

 and also from the American Museum of Natural History, and I 

 would express my thanks to the authorities of these institutions. 



Note: — The order followed is that of Sharpe's Hand List of Birds, 

 and the measurements are in millimeters. 



TETRAONIDAE. 



Lagopus lagopus lagopus (Linne). 



One adult male, shot July 13, on the alps above Tchegan-Burgazi 

 Pass, at 9,500 feet. It was one of a pair that had with them a brood 

 of young. They were in smooth country, in a place where there were 

 no rocks. 



Tetrastes bonasia septentrionalis (Seebohm). 



One young male, Topucha, August 7. This example is nearly full 

 grown, with the adult feathers appearing in the tail and in places 

 on the body. It is, however, too young for positive identification and 

 I refer it to the above subspecies on geographic grounds only. 



It was shot by Dr. Lyman, with his rifle, from a covey which he 

 flushed in the thick forest. Afterwards both he and Mr. Kein hunted 

 assiduously but were unable to find either this covey or another.
