The example from Simunjon is in the plumage of 31. tristis verus, ap. Malh. (Monogr. ii. Ibis, 1872, 

 p. 10) ; and a Banjermassing specimen displays the same characters. The first, although marked ^' ^^^' 

 a male, wants the usual red cheek-stripes; the South-Bornean bird displays only traces of red 

 feathers on the cheeks. Malaccan examples frequently exhibit one or other of the jieculiarities 

 insisted upon by Malherbe as being characteristic of M. tristis (Horsf.), notably the dark breast 

 and under surface generally. All the individuals with the under surface coloured fulvous, with 

 brown cross bands, Malherbe has separated under the title of P. grammithorax {torn. cit. p. 13). 

 That author, however, admits that it is impossible to indicate with precision the separate localities 

 they inhabit. The Marup specimens are in the plumage of P. f/rammithoraw, and they do not 

 differ from some Malaccan and Sumatran examples. The probabilities are that the dark-breasted 

 individuals, M. tristis (Horsf.), are birds not arrived at maturity, and that when in adult plumage 

 they assume the garb which induced Malherbe to regard them as belonging to a distinct species, 

 P. grammithorax *.

" Marup, ? , iris crimson." 



Prince Bonaparte (/. c.) separated the large Bornean Crow Pheasant ; but this example 

 agrees so closely with Malaccan and Sumatran individuals that I cannot recognize its specific 

 distinction. C. eunjcermis can always be distinguished from the continental C. rufipennis, Illiger, 

 by its larger size, by the tail of the full-plumaged bird (?) being blue and not green, and by the 

 interscapular ij region of the bach being coloured like tlie wings. Even in young birds with 

 striated plumage, this part of the back will be found to have some rufous feathers. I have not 

 been able to determine with any certainty whether the rectrices pass from green to blue, or blue ibis, 1872, 

 to green ; but in one stage they are certainly blue, which never occurs in C nijipennis. P- '^^''■ 



If, on comparison, the Javan Centrococcyx [C. bubutus, Horsf. Tr. Linn. Soc. xiii. p. 180, 

 sp. 2) prove to belong to this species, Horsfield's title will have precedence. Both Moore and 

 Cabanis unite it with the continental form ; but, judging from Horsfield's plate and description 

 (Zool. Res., C. phiUppensis, yax. javanica), it is the Malayan species or else nearly allied to it.

" Jambusan, 2 , iris brown." 



In almost perfect plumage. Identical with Javan, Malaccan, and Celebean examples. 



* This view is supported by the fact, above mentioned, that the Simunjon male wants the usual red cheek-stripes. 

 Mr. Everett's notes of the sexes throughout his collection appear to have been made with scrupulous accuracy,
