This is not a Moluccan nor a Papuan species ; still I may mention that, to avoid the confusion with Columba porphyracea, Temm. (1822), it would be better to call it P. roseicollis, Wagl. Besides Java it inhabits also Sumatra, as has been stated by Bonaparte. I have seen many skins from Sumatra, collected by Dr. Beccari. 42. PTILOPUS ORNATUS. The authority of Laglaize for this species being found on Mount Arfak is not correct, as Mr. Laglaize was never there. Mr. Laglaize's specimens, which I have seen, are from Amberbaki, a locality far away from Mount Arfak. 44. PTILOPUS PERLATUS. The locality Aru Islands does not belong to this species, but to P. zonurus. The two are representative forms, one living in Northern New Guinea, Jobie, and Salwatty, and the other in the Aru Islands and in the south of N e w Guinea, on the Fly River, where D'Alber-tis has lately collected several specimens entirely agreeing with those from the Aru Islands. 45. PTILOPUS ZONURUS. Mr. Elliot could have added many quotations to the synonymy of this species; all the references to P. perlatus from the Aru Islands belong to it. Beside the type, I have seen many specimens of this form from the Aru Islands and from the Fly River; and all of them show the grey band at the tip of the upper surface of the tail. P. zonurus has in that respect the same relation to P. perlatus that P. iozonus has to P. jobiensis. It is important to notice that P. perlatus and P. jobiensis are respectively the northern representative forms of P. zonurus and P. iozonus. Mr. Elliot's statement that P. zonurus is barely distinguishable from P. perlatus is rather inconsistent, after he has accepted as distinct P. jobiensis and P. iozonus, which differ exactly in the same particulars as P. zonurus from P. perlatus. 47. PTILOPUS PECTORALIS. The synonymy of this species is not correct. Instead of Columba virens, Less. Voy. Coq. descr. $ \_sic], it ought to be Columba cyanovirens, Less. Voy. Coq. Zool. i. 2, p. 713 (1828). The name of C. cyanovirens was given to the female of P. superbus and to the present species! It is important to notice the mistake, as, if Lesson had really named this species C. virens, this name would have had priority over that of C.pectoralis, Wagl. Isis, 1829, p. 739. From the localities Mr. Elliot has left out Koffiao (Beccari). 48. PTILOPUS VIRIDIS. S. Muller and many others after him have said that this species is also found in N ew Guinea, near Lobo. But this is a mistake which has arisen from S. Muller having (Verh. Land- en Volkenk. p. 22) given the name of Columba viridis to a young specimen of P. pectoralis. |
