coutributioiis on ornithology. One of these by Mr. W. H. 

 Workman deals with the migration ot: Woodcock, and is 

 based on Captain Douglas' paper on the same subject 

 published in the ' Proceedings ot" the Zoological Society ' 

 for 1917. The investigations were conducted on the estates 

 of Colonel W. W. Ashley, M.P., in co. Sligo, and large 

 numbers of breeding birds were ringed. A considerable 

 proportion of these were recovered on the estate in the 

 immediate neighbourhood of the place of ringing, and there 

 can be no doubt that the greater number of the birds bred 

 on the estate are non-migratory and resident ; in addition 

 there are a good many which arrive from the north for the 

 winter months, and a third category is formed by those 

 w^iich are bred on the estate and migrate southward. 



The other bird-paper is by Mr, J. P. Burkitt, and deals 

 with some interesting observations he has made on the 

 subject of the return of the same individual pair of birds 

 to the same nesting-spot each year. He also writes at con- 

 siderable length on the subject of "frame-nests," in some 

 cases khown as ''cocks' nests. ^' These nests never have 

 any lining, and Mr. Burkitt believes that they are con- 

 structed by unmated cock birds. In some cases later on 

 a mate is obtained and the nest is at once completed, and 

 the eggs laid and incubated. Mr. Burkitt's observations 

 were made chiefly on the Whitethroat and the Wren.

The editors of this Journal and the Anglo-Siamese com- 

 munity of Bangkok deserve all congratulations on the 

 couipletiou of their second volume, which contains many 

 papers on various subjects of zoology and botany relating 

 to Siam. The most important contribution relating to 

 ornithology is the junior editor's list of the birds of 

 Bangkok, of which two instalments appeared in the pre- 

 vious volume, and two are now added, bringing the list,
