from C. albertisii as follows : the large bare space round the e3'es, which doubtless 

 was the reason for the creation of the genus GijmnojiIi(i/ig, is replaced by a very 

 small bare patch ; the throat and sides of head are whitish instead of dee]) purj)lish- 

 chestnut, the abdomen is much lighter — rather bufi'y than chestnnt ; the upperside, 

 and especially the head and neck, are very much lighter ; the tail wants the wide 

 grey tip. 



We have of ('. albirtisii the following specimens : — 



1 Serui, Jobi (Uoherty coll.). 



3 Arfak (from Brnijn's hunters). 

 3 Konstantinhafen (J. Knbary coll.). 

 3 ? Sattelberg (Erik Ny man "coll.). 



2 Moroka district, British Xew Guinea (H. 0. Forbes coll.). 



3 Goodeuough Island (A. S. Meek coll.) 



02. Columba albigularis (Bp.). 



This pigeon belongs doubtless to the same species as C mrtallicu, griseigidaris, 

 leopoldi, and several others. They are all the same bird in differently attired 

 forms, representing each other on the various islands which they inhabit. The 

 white throat of C. alhiyidavii is rejjlaced by a pale grey one in C. grisi'igularis, 

 and by a dark slaty-grey one in G. leopoldi, which may be descriljed as a 

 somewhat smaller albigularis with rufous abdomen. Probably ('. castaneiwjjs, 

 vitiensis, hypoenochroa, nitens, janthina, and perhaps still more, belong to this same 

 group ; the oldest S]iecific name wonld then probably be me/allica. For a full 

 discussion we have not at present sufficient material. Of albigulai-is we have the 

 following 19 skins : — 



4 adults, 1 pull. Soa Island, Little Key group (H. Kiihn coll.). 

 cf ad. Maar, Ceram-lant (H. Kiihn coll.). 



5 Mysol (H. Kiihn coll.). 



cJ Mansinam (from Brnijn's hunters). 



2 pull., Dutch New Guinea (from feather-dealers). 



? Konstantinhafen (Knbary coll.). 



¥ Milne Bay, S.E. Xew (juinea (A. S. Meek coll.). " Iris light yellowish-red ; 

 feet purple-red ; bill purple-red with lavender-grey tip." 



2 c? Mt. Cameron, Owen Stanley range (A. S. Anthony coll.). 



? St. Aignan, Loiiisiade group (A. S. Meek coll.). 



2 Tagnlandang, collected by Cursham's natives. (Cf. Meyer and "Wiglesw. 

 Birds of Celebes, 11. p. 634.) 



1 Gnnoiig Api, collected by Cursham's natives. (Ibid.) 



? Snla Mangoli, W. Dohert)'. (Cf Nov. Zool. V. p. 13(i, where Mr. Hartert 

 has discussed this specimen at length.) 



A series from Sula Mangoli would be most desirable Cor comjiarison with 

 specimens from other countries. 



The Genus MACROPYGIA. 



Being much interested in this genus, we have ventured to review it entirely, 

 as far as we are acipiaiuted with its members. Also here, like everywliere, we 

 find a number of well-defined grou])s which we consider to deserve full specific 

 rank, while a great many others are merely representative forms of each other.
