MR. P. DERANIYAGALA, director of the National Museums of Ceylon, writes, pointing out that in the obituary notice of Hugh Whistler appearing in NATURE of August 21, 1943, no reference is made to his last major work, the avifaunal survey of Ceylon by the British and Colombo Museums. Whistler worked out the collections, and the results are now being printed in the Colombo Museum journal, Spolia Zeylanica; they should be published by about May.
