100 DRS. HARTLAUB AND FINSCH ON BIRDS [Jan. 16, 



with the type-specimen described by us. We are now of opinion 

 that this plumage is not that of the young bird, but of the old.

Three specimens from Mackenzie Island (Capt. Peters), and two 

 from Uap (Kubary), where this species had not been previously ob- 

 served. 



One specimen, determined as female by Mr. Kubary, agrees in 

 colour with the old male ; a young one (marked as male) is of a 

 uniform sooty brown, with slight metallic reflexions on the upper 

 parts. " Iris yellow " {Kubary). 



The dimensions vary very much in this species, but do not equal 

 those of the allied C. corvina, Kittl., from Ualan.

An old specimen from the Pelew Islands (Capt. Heinsohn) proves 

 to be specifically identical with our common Cuckoo. In comparing 

 this specimen with an old male from Germany, we can notice only 

 that the white underparts are tinged very faintly with yellowish, and 

 that the dark cross bands on the under tail-coverts are less marked. 

 The zigzags on the anal region are absent. 



I have also seen in the Leyden collection a specimen labelled 

 "Lugon," which was entirely similar to the European bird.

The occurrence of the Common Cuckoo in the Pelews is a new fact 

 in the geographical distribution of this species.

 Cuculus himalayanus, Swinh. P. Z. S. 1863, p. 265. 



Three specimens from the Pelews (Capts. Heinsohn and Peters) 

 are nearly in full plumage — one changing the feathers of the upper 

 parts from brown into dark slate, and two young ones in the dark 

 rufous plumage barred with dark. I have for comparison only an 

 old specimen from Amboina at hand, which shows no difference.
