36 NOVITATES ZOOLOGICAE XXII. 1915. 



also with a skin from the late GodefFroy Mnsenm, collected at " Naunka," 26. v. 1879, 

 by Th. Kleiuschmidt. The distribution of this very rare species is iuterestiag. It 

 is only known from the Credner Islands, Uatom (a small island to the north of the 

 Gazelle Peninsnla), and from " Nannka" : where this place is, we cannot find ; it is 

 not likely to be " Nanuk," inland in the Gazelle Peninsula, as M. sdatcri was not 

 found there by Dr. Dahl, nor anywhere else on the groat island of New Britain. It 

 appears to be a bird of outlying small islets, and it is most interesting to find it on 

 Damj)ier Island, far west of the New Britain group of islands.

 6623, 6626, 6627, 6794, 6795, 6806). 



It is very curious that this bird, which we have hitherto only had from south- 

 eastern New Guinea and the D'Entrecasteaux Islands, occurs on Damijier and 

 Vulcan Islands.

Erylhrura trichroa goodfellowi O.-Grant, Bull. B. 0. Clnli xxi.x. p. 29 (1911 — Moroka Mouutaias, 

 British New Guinea). 



The races of E. trichroa have now reached the number of seven ! Five of them 

 have been discussed by one of us in Nov. Zool. 1900, pp. 6 and 7. Since then 

 Mr. Ogilvie-Grant described a bird from the Moroka Blonntains, British New 

 Guinea, and Stresemann one from Ceraui. Mr. Grant {Bull. B. 0. Club x.x:ix. p. 29) 

 compared his new race only with " E. trichroa Kittl.", instead of the two geo- 

 graphically nearer, E. trichroa papuana from Arfak and E. trichroa modesta from 

 the Northern Moluccas. From modesta his goodfellowi differs only in the less 

 yellowish tinge of the plumage and the deeper blue of the forehead and ear-coverts, 

 bnt some Moluccan skins are hardly separable ! The type oi E. t. papuana Hart, 

 differs by the great extent of the blue on the crown (see original description), and 

 has a huge bill. A similarly large bill and equally long wing is found in some 

 specimens from the mountains of British New Guinea, in the Tring Museum, but 

 not one of those before us has the blue equally far extended on the head. It seems, 

 therefore, that we have to distinguish seven races, as follows : 



E. trichroa trichroa (Kittl.) — Caroline Islands. 



E. trichroa modesta Wall. — Northern Moluccas. 



E. trichroa pinaiae Stres.— Southern Moluccas (Cerani) : the differences stated 

 by Stresemann are obvious, but the new race has been rather daringly described 

 from only one adult and one semi-adult male ! 



E. trichroa papuana Hart. — Arfak, New Guinea. 



E. trichroa goodJ'eUowi O.-Grant.— Mountains of British New Guinea, prob- 

 ably nearly the whole of Eastern New Guinea, as we have received a series from 

 Vulcan and Dampier Islands, which we cannot separate from those of British Papua.
