ON THE GENUS PTILOPUS. 115 



make a few remarks. Sehlegel (Nederl. Tijdschr. Dierk. iv. p. 24, 1871) 

 says that the females of the four species enumerated above offer the same 

 coloration as the males. But of P. musschenhroeki, according to the Leiden 

 Catalogue (Mus. P,-B. Col. 1873, p. 23), there were only the males in the 

 hands of Prof. Sehlegel ; and the female specimen which I possess, from 

 Mafoor, has neither grey on the wing nor red on the throat, and appears to be 

 an adult. Further, of the two female specimens of P. pectoralis which I 

 possess, from Passim and Rubi, neither shows a trace of red on the throat, as 

 all males do (the younger less than the adult) ; but they have the grey on the 

 tertiaries. I therefore do not share in Schlegel's view that the females of 

 these four species are all like the males, but restrict this opinion for the 

 moment to P. pectoralis and P. musschenbroekii, having no personal experience 

 as to the two others." 



Prof. Sehlegel only separates Ptilopus musschenhroeki from P. viridis as 

 P. viridis geelvinkiamis, therefore giving no full specific value to it. Salvadori 

 first did this, in his ' Prodromus Ornithologise Papuasige et Moluccarum ;' 

 and it appears, according to his remarks, that Dr. Meyer also does so, and, 

 in my opinion, correctly. 



Mr. S. C. T. van Musschenbroek, after whom Von Rosenberg named 

 this fine species from the islands of the Geelvink Bay, has been for many years 

 a Dutch official in the East, and is a gentleman of high scientific attainments. 

 He served for years on the island of Java in different official positions, and 

 last at Buitengorz, near Batavia, as Assistant Resident. From there he 

 advanced as Resident (Prefet) to Ternate, the chief place of the Moluccas, 

 near Kalmahan, and a good starting-point to New Guinea. The Dutch 

 Government planned an expedition to New Guinea under his care ; but the 

 war in Atchin, on Sumatra, prevented it. Mr. van Musschenbroek then 

 became Resident at Menado, in North Celebes — that is to say, Govermental 

 Chief of the Minahassa, the countries round the Tomini Ray (Gorontalo),
