The examination of specimens for signs of moult brought 

 to light five cases of feathers lacking pigment. In each bird 

 so affected there was but one white feather; in four of the 

 cases the feather was in some part of the neck, and in the 

 fifth in the breast. Four of the specimens are from Indefat- 

 igable Island and one from James. The bird from James was 

 taken in December, and the birds from Indefatigable, in No- 

 vember, January, and July. 



Gallinula galeata: Florida Gallinule 



Albemarle and Chatham islands. 



Florida Gallinules proved to be tolerably common in the 

 large salt-water lagoons fringed with mangroves, in the vicinity 

 of Villamil, Albemarle Island, in November and August. 

 They were wary and secretive. Usually they kept out of gun- 

 shot, and not more than two or three were seen at a time. An 

 apparently immature male was shot by Mr. Hunter on a fresh- 

 water pond at about one thousand feet elevation near Progreso, 

 Chatham Island, on October 17. 



In a high-plumaged male taken on southern Albemarle on 

 March 6, the amount of white on the edge of the wing is ex- 

 tensive, but it is equaled in a specimen from Merced County, 

 California. The tarsi of the Galapagos bird, however, have 

 dried of a variegated orange-and-red color, while those of the 

 California examples have dried chiefly of a dark olive-green. 



The measurements in millimeters of the adult male from the 

 Galapagos Islands are as follows : Wing 183 ; tail 73 ; culmen 

 and frontal shield 47; greatest width of frontal shield 15.3; 

 tarsus 53; middle toe 64. 



The extreme and average measurements in millimeters of a 

 series of seven adult males from Merced County, California, 

 are as follows: Wing 175-190 (182) ; tail 70-74 (72) ; cul- 

 men and frontal shield 40-44.9 (42.4) ; greatest width of 

 frontal shield 10.2-15 (13.1) ; tarsus 48-57 (53.1) ; middle toe 

 63-70.7 (65.8).
