with tliose in New Zealand, without being able to discover any constant 

 difference sufficient to establisb them as new species. The remarkably small 

 specimens from Auckland Islands might claim a place as a first defined 

 species, were it not for the, comparatively speaking, great contrast they 

 exhibit to each other in transition. The species differs in measurement to 

 an extraordinaiy degree. The length of wing sometimes varies as much 

 as 16'". 



2. Flatycercus auriceps, Kuhl. 



= CyanorampJitis mcdiierhi, Sou. 

 abounds in the Middle and North Islands (Eamsay), South Island,* and 

 Auckland Isles (Antarctic Exped.) The specimens from the last-named 

 district form, according to De Souance, a distinct species (PL mallierhi), 

 which, however, according to my examinations, agree perfectly in kind. 



3. Flatycercus forsteri, Knsch ("Parrots," II., p. 287). 



== PI. pacijicus, Forst. (" Descr. anim.," p. 73, No. 80). 

 differs from PI. novcB-zecdandice, Sparrm., in the absence of red spots on the 

 tail. The future will show whether this difference is in reality always con- 

 stant. Yery little, in fact, is known as yet about this parrot ; I know of only 

 one specimen in the British Museum, which agrees almost perfectly with 

 Forster's description. Perhaj)s it is PI. novce-zealandicd, changed by age. 



The remaining allied species, which belong to the sub-genus Gyanoram^ 

 pirns., are — 



Flatycercus unicolor, Vig., of unknown origin, but for the present hj no 

 means to be effaced, according to Mr. BuUer's intention. 



Flatycercus pacijicus, Eorster, ("Descr. anim.," p. 238), from the Society 

 Islands (Tahiti) ; and 



Flatycercus idieteanus, G-ml., New Hebrides (Tanna), or Society 

 Islands (14). 



Eam. CucuLiDJE. — I cannot find out where Mr. Grould made this remark; 

 In his "Birds of Australia" (folio), he expresses his regret that the nest of 

 the Euclynamys flindersi is still unknown, and again in his " Handbook of 

 the Birds of Australia," Yol. I., p. 632. Nevertheless, in describing the 

 genus Eudynamys, he says explicitly, "all species are parasitical." 



Since Ave are tolerably well acquainted with the range of Eudifnamys 

 faiteftsis, we can say, approximately, where it hibernates; In any case it 

 must be on some of the warm islands, the Friendly, Society, Marquesas^ 

 Yiti, and Samoa group, which hitherto have been knovra. to be frequented 

 by the species. 



Ghrysococcyx lucidus, on the other hand, must frequetit other districts
