than the middle toe, and of equal length ; the claws of the 

 middle toe large, and pectinated on the sides, those of the 

 other toes small. ^U^M^.' .

GENERAL colour variegated rufous- white, yellowish, and 

 reddish-brown ; scapularies marked with oblong blackish- 

 brown spots ; on the throat in front a triangular white mark ; 

 the four external wing-feathers brownish-red, each with a 

 white patch. Tail banded with brownish-black. Length, 

 9" 3'" ; wing, 6" 3"' ; tail, 4" 6"'. 



Mr. Swainson, in alluding to the difficulty of describing the singu- 

 larly variegated, dull-coloured plumage of this family of birds, makes 

 the following remarks : " We might almost say, that in regard to 

 colour, if a person has seen one species of Caprimulgus, he has seen 

 all. There are, it is true, trifling variations, but these are sometimes 

 so slight that none but an acute ornithologist would detect them ; 

 while, from' their very nature, they are so difficult to describe, that the 

 most laborious descriptions fail to convey their differences to the mind 

 of the reader ; the different shapes of the marks, bands, and spots, the 

 manner in which they are blended, and the diversity of tints under 

 which the different colours of brown, grey, rufous, and whitish appear, 

 often upon a single feather, in these parti-coloured birds, defy all clear 

 description, and render it impossible by these indications only, to 

 discriminate the species." 



Fully coinciding in these views, which apply equally to most of the 

 partridges, I purpose simply to indicate our species of goatsuckers by 

 some particular point in their appearance, referring the student to 

 those works in which more elaborate descriptions have been given. 



Dr. Smith says that this species may be readily distinguished by a 

 number of strongly-marked and well- defined oblong, liver-brown 

 spots, each more or less distinctly edged with white, or light buff,
