Colombo, The Colombo Museum, [1914]-1920. Four papers in one. 8vo (23.3 x 14.8 cm). 207 [32; 82; 60; 33] pp.; 4 [0; 2; 1; 1] plates. Contemporary half calf over red cloth boards. Gilt title on the spine.

In the third paper, the author describes the last two papers as "instalment[s] of the rough draft for the handbook on the birds of Ceylon". That work was published in 1925 but does not contain all the data presented here. The first paper is mainly on distribution of bird genera, then (and now) occurring on Ceylon in time and space. All three works are published in Spolia Zeylanica, the Bulletin of the Ceylon Museum, Volume 10, together with several other contributions to the natural history of what is now Sri Lanka. Joints rubbed, otherwise very good. Rare.
