Vo. II, Pr. IT] LOOMIS—A REVIEW OF THE TUBINARES 81 
of breast, and upper and lower tail-coverts are much coarser 
in some examples than in others. Their relative prominence 
also varies, giving the surfaces as a whole a lighter or darker 
appearance. The general aspect of the lower parts is lighter in 
some specimens and darker in others. In the extreme light 
manifestation, the breast, abdomen, and sides are finely vermic- 
ulated with white and gray, growing darker laterally and 
posteriorly. In the extreme dark style the vermiculations are 
coarser and the flanks and abdomen are nearly uniform dark 
gray. The tail is smoky-brown, becoming white on the con- 
cealed portion. ‘The colors of the naked parts of the adults 
in life were as follows: Bull yellow; bare skin in interramal 
space azure blue; iris dark brown; orbital ring black; feet pale 
bluish” (Gifford). No. 1237 C. A. S. has thirteen rectrices. 
One specimen, obtained June 28, is in good feather, and is 
apparently just finishing a moult. In two other summer speci- 
mens the plumage is in fair condition, but in the rest of them 
it is worn. The autumn specimens are generally much worn, 
and many of them are replacing the feathers of the breast and 
abdomen, the postnuptial moult having commenced. 
In the subjoined table are the dimensions in millimeters of 
twenty-two males and forty females.

In the flesh the length of five males in millimeters was 890, 
890, 905, 920, 935 and of four females 850, 865, 870, 870. 
The extent in a single male was 235 cm. and in a female 
232 cm. 
It is apparent from the measurements given above that the 
females average smaller than the males.
