TOWNSEND AND WETMORE: THE BIRDS. 173 



8. IXOBRYCHUS SINENSIS BRYANI (Seale). 



Ardeita bryani Seale, Occas. papers Bernice Pauahi Bishop mus., 1900, 1, 

 no. 3, p. 27. (Guam). 



An immature male of the Little yellow bittern was taken on Guam, 

 24 February, 1900. Comparison of a large series of these small 

 bitterns in the U. S. N. M. from various localities (including adult 

 birds taken on Guam) shows that the bird described by Seale as 

 Ardctta hryani may be recognized as a valid form of the widespread 

 Ixohryckus sinensis.
