Zoology of New Guinea. 321 



Lamprococcyx LuciDUs (Gm.), Ramsay, /. c. p. 256. 



I suspect that the bird so named is L. plagosus (Lath.), a 

 different species from L. lucidus (Gm.), which I only know 

 from New Zealand. 



Lamprococcyx meyeri, Salvad., Ramsay, ibid. 



I only knew this species from the Arfak Mountains. It 

 would be interesting to compare the southern specimens with 

 the northern ones. 



Cacomaxtis assimilis, Gray, Ramsay, ibid. 



This cannot be Gray^s species, which never has the under- 

 partsrich castaneous redorrufous. Mr. Ramsaydocsnotthink 

 that the specimens doubtfully referred by him to C. assimilis 

 belong to C. castaneiventris — to which species I have assigned 

 specimens from Naiabui in the south (Prodr. CuculidcE, sp. 5), 

 from the Arfak Mountains, from Salwatty, and from the 

 Aru Islands, which seemed to me the same as the Australian 

 ones. 



Cacomantis dumetorum, Gould, Ramsay, /. c. p. 257. 

 This, in my opinion, is not diiferent from C. tyiiibonomus 



(S. Miill.). 



Centropus spilopterus. Gray, apud Ramsay, /. c. p. 258. 



Mr. Ramsay, following Mr. Sharpe (Jouru. Proc. Linn. 

 Soc. xiii. pp. 81, 310, 491), now assigus to C. spilopterus, 

 Gray, the bird which on previous occasions has been described 

 by me under the name oi Polophilus nigricans, Salvad., Anu. 

 Mus. Civ. Gen. ix. p. 17 (1876), and which has been assigned 

 by Mr. Ramsay to Centropus melanurus, Gould (Proc. Linn. 

 Soc. N. S. W. i. p. 394). I have already stated (Prodr. vi. 

 CuculidcB, sp. 36) that Mr. Sharpe was in error; and I take 

 this opportunity to explain that his mistake arose from 

 the fact of his not having fully adult specimens of C. spilo- 

 pterus in the British Museum. Polophilus spilopterus (Gray), 

 (very badly named) in the adult state is perfectly uniform 

 greenish black ; and it is not such a typical Polophilus as 

 my P. nigricam, which, when fidly adult, has the wings and 

 the tail marked vrith light bars and freckled with rufous.
