100 CUCULUS AUDEBERTI. 



The whole underpart of the Madagascar species is of an 

 uniform pure white, without the least trace of longitudinal 

 streaks on the chest, or transverse bands on the breast, 

 flanks , and belly ; nor is the chest by no means washed with 

 rufous. The feathers of the shanks equally white and only 

 marked , instead of by numerous regular bands ,by a few dark 

 transverse spots. The under tail-coverts , one inch longer 

 than in Guculus sparveroides , show , on the contrary , 

 each , several large and complete transverse black bands , 

 whereas in the Indian species this marking occurs only 

 accidentally and is , moreover , reduced to a few obsolete 

 and imperfect transverse spots The under coverts of the 

 wing are pure white, and not of a rufous colour, transversed 

 with brownish black bands. The black bands , so conspicuous 

 on the inner webs of the quills in the Indian bird are entirely 

 wanting in the species of Madagascar. The dark colour 

 of the upper parts is , in our new bird , more dusky , 

 without any reddish hue or ashy tinge. The tail-feathers 

 show the usual terminal large black band, but it is bor- 

 dered , at the end , with white , and followed by a white 

 spot, but the other bands, four or five in number, which 

 render the tail-feathers of the Indian species so conspicuous , 

 do not exist in our new bird. Last of all, it must be 

 observed, that the bird has the extremities of both series 

 of quills , and of the great wing-coverts margined with pure 

 white, and that the bill is stronger and much larger at 

 its base , and that the nostrils have not a sort of tubular 

 aspect but that of a simple oblique split. 



Mr. Audebert , to whom this species is dedicated , found 

 the iris of the eye of an uniform black color.
