unlike auytliing in the British Museum collections ; unfor- 

 tunately only a single skin was obtained, and that one of 

 a young bird, so that it uould be hazardous to describe 

 it as new. The highest altitude at which a bird was 

 obtained was 18,500 feet on the eastern slopes of Mt. 

 Everest, where Mr. Wollaston procured an example of 

 the Alpine Accentor, Laiscnpus collaris nipalensis. 



Personal. 



Mr. T. Chrostowski, of the Polish Museum of Natural 

 History at Warsaw, writes that he is shortly leaving for 

 South America to renew his investigations into the avifauna 

 of that continent, which were interrupted by the outbreak 

 of the war. He will be glad to correspond with any 

 ornithologists interested in Neotropical Birds and to 

 exchange papers with them. His address is as above. 



Notice to Contributors. 



At the last meeting of the Committee of the Union the 

 following resolution was proposed by the Chairman and 

 seconded by Major Sladen, and carried unanimously : 



" In consequence of the great expense incurred in the 

 correction of MS. and proof of the papers sub- 

 mitted to the Editor, authors are warned that 

 they may be called upon to pay for any corrections 

 made other than printers' errors/' 



It has been found that the cost of corrections in proof 

 of 'The Ibis' for 1920 and 1921 was 25 per cent, and 

 28 per cent, respectively on ihe total cost of printing the 

 letterpress, and the Committee feel that this is much higher 

 than it should be and that considerable saving could be 

 made if authors were more careful in the preparation of 

 their manuscript or typescript before sending it to the 

 Editor.
