cal with pallidus of Hodgson,) niveus and Kienierii, all of which are in 

 the Asiatic Society's Museum, approaching the restricted Aquil(S in all 

 except its lengthened tarsi. The four species of true Nisaetus here 

 mentioned, I must further add in reference to Mr. Jerdon's sugges- 

 tions on the subject, are quite distinct from each other ; but I am 

 not satisfied of the identity of A'', cristatellus apud Elliot, with the bird 

 so named in Jardine and Selby's ' Illustrations of Ornithology'. 



Rhipidura hypocantha, Blyth, noticed in the description attached 

 to Plate II, has been justly separated by Mr. Hodgson by the generic 

 appellation Chelidorynx. 



Plate III. — Respecting the species here figured (which I still prefer 

 to class in Phcenicophceus, as this group is recognised in my monograph 

 of eastern Cuculidce), Mr. Jerdon has mistaken my meaning in the 

 passage which he quotes. What I intended by the expression — 

 " No doubt the present species is alluded to in both cases," was, 

 that the Indian bird referred to by Levaillant and the Ceylon bird of 

 Daniell, were identical with Mr. Jerdon's species, but certainly not 

 with the African Serisomus cristatus. I may add, that the Ph. 

 tristis, Cuv. Melius tristis of Lesson, and my Ph. longicaudatus has 

 just been obtained in the vicinity of Calcutta i and that a third 

 species, the Ph. Sumatranus (Cuculus Sumatranus, Raffles, and appa- 

 rently Melias Diardi of Lesson,) is common on the hill ranges of Assam. 

 The Zanclostomus sirker appears to me to be very decidedly separable 

 from the above group, and to be rightly classed by Mr. Jerdon. 



Plate VI. — Prima cursitans of Franklin. Both this and the various 

 other Indian Prinice of authors, certainly do not appear separable as a 

 group from the African Drymoicce, numerous species of which are 

 figured in Dr. A. Smith's ' Zoology of South Africa.' 



Plate VII. — The Asiatic Society has recently received from Mr. 

 Hodgson, a female specimen of Tchitria Paradisea, in similar parti- 

 coloured plumage to that of the male figured by Mr. Jerdon. As 

 the middle tail-feathers of this specimen are full grown, and do not 

 exceed those of an ordinary female, instead of being greatly elongat- 

 ed as in the male, this circumstance may help to convince Mr. 

 Jerdon of the accuracy of my former statement, that " both sexes 

 attain the white garb with full maturity," albeit the sex of a white 

 female may not have yet been ascertained by actual dissection.
