1873, p. 696, pi. Ivii.)? in the Catalogue of the Leyden Museum (Mus. P.-B. 

 ColumhiB, p. 27) writes : — 



" General tint green, slightly bronzed on the sides of the head. Least 

 primaries with a large apical patch of a green-greyish white colour. Under 

 tail-coverts and abdomen citron-yellow. Male adult easily known by the 

 following characters — breast and abdomen of a fine purple-lilac, a large fine 

 citron-yellow band on the breast, passing below into white, and a dark violet 

 patch on the lores." 



Herr von Rosenberg only gives the following note in his ' Reistochten,' 

 published in the year 1875, p. 143 : — 



" Male. Green ; the halfmoon-formed breast-shield lively citron-yellow, 

 with a broad white band below ; in the middle of breast and on the belly a 

 light-purple-lilac patch ; on the lores a little dark-violet patch ; abdomen 

 and under tail-coverts pale citron-yellow. 



''Length. Wings 3" 11'" to 4" 3'", tail 2" 1'" to 2" 3" 



" Habitat. Mafoor and Schouten Eilanden." 



In the letterpress of his interesting work the traveller says, in the 

 chapter on Mafoor, p. 37 : — 



" Among the two Parrot-Pigeons, the one of which I named Ptilopus 

 speciosus, the other P. musschenbroekii, the former is conspicuous by its grey 

 colour. It is related to P. rivoli, but has a golden-yellow shield on the 

 breast. P. musschenbroekii is unlike P. viridis from Amboina. According to 

 Prof. Schlegel, in Nederl. Tijdschr. v. d. Dierk. iv. p. 23, P. musschenbroekii 

 is only a variety of P. viridis*. Both species, which I again found on Soek, 

 together with my Lamprotornis magniis, are less common." 



* Later (Mus. P.-B. Columba, J873, p. 23), Prof. Schlegel called the species Ptilopus viridis 

 geelvinkianus, showing that he considers it, if not a species, something more than a variety.
