1877.] DR. O. FINSCH ON BIRDS FROM NIUAFOU ISLAND. 783 



2. DOMICELLA FRINGILLACEA (Gm.). 



Native name Hega, Hiibner. 



Three specimens (October 18/6); not differing from those from 

 Eua. A young bird shows on\y a few red feathers on the vent ; but 

 the red and blue on the head is the same as in old birds. 



3. EUDYNAMIS, sp. ? 



Mr. Hiibner {in lift.) mentions having heard the call -note of a 

 Eudynamis, which, no doubt, will turn out to be E. taitiensis 

 (Sparrm.). 



4. COLLOCALIA, sp. ? 



There is no specimen of this genus in the collection ; but Mr. 

 Hiibner writes: — "The Beha-beka {Colloccilia) breeds in a hole of 

 a rock on the lake in the interior of Niuafu, I always found two 

 eggs or young ones in each nest. The natives laughed when I told 

 them I wanted to obtain eggs of these birds, as they believed them 

 not to lay eggs at all." 



5. Aplonis tabuensis (Gm.). 



Native name Megi, Hiibner. 



Three specimens (October 1876). The underparts look a little 

 more brownish ; but this may be caused by the specimens not being 

 in full plumage and partially moulting ; otherwise there is no differ- 

 ence from Eua birds in colour or dimensions, except that the bill is 

 a little shorter ; but this may also be a sign of immaturity. 



6. Ptilonopus porphyraceos (Forst.). 



Native name Kulu-kulu, Hiibner. 



Two specimens, adult, male and female (October 1876) ; are 

 exactly like specimens from Eua. 



This species is easily distinguishable from Pt. fasciatus, Peale 

 (who first obtained that species on the Navigators'), by the dark 

 purplish-violet spot on the middle of the vent, which in Pt. fasciatus 

 is dark purplish-vinaceous. All the specimens which I have in- 

 spected from Upolu and Uea (Wallis Island) agree in this respect ; 

 but I have no specimens from the Vitis for comparison. According 

 to Mr. Layard (P. Z. S. 1876, p. 49.5) the Viti bird is of a different 

 species, which he erroneously calls Pt. apicalis, Bp. As Bonaparte 

 established his species on a specimen from Vavao (Tonga Island), it 

 belongs undoubtedly to Pt. porphyraceus, whereas the name fascia- 

 tus, Peale, should stand for the Navigators' bird, having been founded 

 on specimens from this locality. If the Vitian Ptilonopus is really 

 different from Pt. fasciatus andPt. porphyraceus, it must be renamed. 



7. Carpophaga pacifica (Gm.). 



Not in the collection, but observed by Mr. F. Hiibner. 



8. Megapodius STAiRi, Gray, P. Z. S. 1861, p. 290 (Samoa!). 



M. pritchardi, P. Z. S. 1864, p. 41, pi. vi. (Nina-fou).
