" Mallett" of the natives. 



Wild Jungle-fowls have not yet been recorded from the Pelews. 

 Mr. Kubary notices the very rare occurrence of half-wild fowls in 

 the interior of Uap.

 & 117. 



One specimen from Pelew {Capt. Heinsohn), two from Mackenzie 

 {Capt. Peters), and three from Uap {Kubary). 



As regards the specific distinctness of this species from Ch. plu- 

 vialis we must refer to what we have said (Joum. f. Orn. 1870, 

 p. 139). The specimens contained in this collection confirm our 

 opinion, as will be shown in the following measurements : —

Specimens from Pelew {Capt. Heinsohn), Mackenzie {Capt. Peters), 

 and Uap {Kubary). Some of them still show signs of the summer 

 plumage ; others are in the perfect winter dress.

31. Ardea sacra, Gmel. ; Hartl. P. Z. S. 1867, p. 831 ; H. &F. 

 ibid. 1868, pp. 8& 118. 



Fourteen specimens from the Pelews {Capt. Peters) and Uap 

 {Kubary) ; amongst them eight slate-coloured specimens, five white 

 ones, and one in the reddish-brown plumage of the young bird. 



The great variation in colour and size which this species exhibits 

 we have already explained several times, especially in our paper on 

 the birds of the Tonga Islands (Journ. f. Orn. 1870, p. 136). We 

 have also stated that the white birds are by no means young ones. 

 The large collection before us confirms all these statements fully. 



There are two slate-coloured females, one with a narrow interrupted, 

 the other with a broad well-defined white stripe on chin and throat, 

 shot in December 1870, on which Mr. Kubary notices on the label, 

 " ovaries with full-developed eggs, some more than 2"' long ;" whereas 

 he remarks on a uniform white male shot at the same time, " testi- 

 cles very large." This latter male specimen is in full plumage, with 

 full-grown scapular feathers, whereas one of the slate-coloured females 

 shows still some moulting-feathers.
