to form the big bend shown on maps. These various ranges must be of 

 considerable height, though the altitudes from available information 

 are uncertain. At one point there was taken a new species of blood 

 pheasant {Ithaginis), a group that is only found at considerable 

 elevations. From the valley of the Mekong, Kock turned east again 

 and collected for a short while on the plain of Youngning, just east 

 of the big bend of the Yangtze, and then crossed over into the south- 

 west Szechwan to visit in the latter part of February, 1924, the 

 independent lama kingdom of Muli or Mili on the Litang Eiver. 

 This' was the only work done outside of Yunnan and ended the col- 

 lection of birds for the trip. 



The result of the year's bird collecting was something over 1,600 

 excellent skins, which were splendidly packed and reached their 

 destination in Washington in fine shape. 



Doctor Rock has issued ^ two beautifully illustrated articles dealing 

 with the country traversed. A staall map that he has published 

 of the northern part of the territory explored indicates most of the 

 localities mentioned in the following report. 



Three birds in this collection have turned out to be apparently 

 unnamed.^ The collection as at present worked out contains 244 

 forms, which is a remarkable showing for a collector busied largely 

 in the procuring of plants. 



J. D. La Touche has published ^ an account of a collection made 

 by hitoself in southeast Yunnan, wherein is given a list of the 

 important papers on the ornithology of the Province, which need 

 not be repeated here. Since his paper was written three large addi- 

 tional collections have been received by the Tring Museum and 

 reported upon by Lord Rothschild.* The birds collected by the 

 Stotzner expedition have been worked out at the Dresden Museum 

 by various specialists,^ but only the early parts of the report had 

 reached the United States when this manuscript was completed. 

 The route on this last expedition seems to have been "more to the 

 north through Szechwan. The two volumes of the Fauna of British 

 India, Birds, second edition, by Stuart Baker, so far published 

 completes the list of important ornithological papers and works on 

 this part of China in recent years. 



The present list is published as a record of the fine collection made 

 by Doctor Rock, trusting it may add something of interest to the 

 distribution and taxonomy of the birds of this part of China, as yet
