to white, gradually and evenly marked there as elsewhere. Beak and

Notes on Aptoso-Chromatism. 
BY WALTER IIOXIE, FROGMORE, S. C. 
I have had several interesting letters since the 
appearance of my article in the April O. and O., 
and as perhaps more of its readers may feel at 
least a curiosity to know something more of my 
method of studying Aptoso-chromatism I subjoin 
the notes taken to-day on those of yesterday’s 
specimens. 
Sanderling $ , 1928, 4-23. Moult nearly com- 
plete. No signs of breeding plumage except a 
few feathers on the upper parts. Breast and neck 
pure white. Testes minute.
