Three individuals possessing the same malformation are figured and described. Considering the rarity of such deformity among birds, it is curious to find it occurring with such comparative frequency in one species. One of these examples was originally reported by H. K. Coale (Auk IV, 1887, pp. 331-333) ; the other two are here figured for the first time.
