Inasmuch as Galapagos specimens exhibit considerable in- 
dividual variation in the dimensions of the bill and in the depth 
of the fork of the tail, it is evident that long series from the 
Eastern Atlantic, Galapagos, and Hawaiian islands must be 
compared before it can be determined whether or not this 
species is subject to geographic variation in size.* Further- 
more, the depth of the fork of the tail is an unreliable measure- 
ment, unless the rectrices are fully grown and unworn. 
No. 496 C. A. S., male: Wing 153 mm.; tail 66.3; fork of 
tail 6; culmen 14.3; depth of upper mandible 5; tarsus 21.1; 
middle toe and claw 21.8. 
The two eggs of certain identity, referred to above, are 
white, more or less discolored through incubation. One of 
them is ovate in form, inclining to elongate ovate, and the 
other is elliptical ovate. ‘They measure respectively: 32.4x 
23.4 mm. ; 33 x 21.4 mm.
