98 On Fijian Species of Pachycephala. 



cifically distinct. But this is not a case in point. Dr. Gadow's 

 contention is that there is no difference between examples from 

 Kandavu and others from Ngau. He is not willing to admit 

 even a subspecific difference between them. I take quite 

 another view of the question. I do not regard the two 

 species as very closely allied. The affinities of P. kandavensis 

 are not with P. vitiensis, which has black rectrices, but with 

 P. chlorwa, a species inhabiting the New Hebrides and 

 agreeing with P. kandavensis in having an olive tail. 



As regards Mr. Ramsay's description, it seems to me to be 

 a good one, and as Dr. Gadow does not point out where it is 

 defective it is impossible to guess which part of it he has 

 misunderstood. Besides the diff"erence in the colour of the 

 tail, which is very marked, P. kandavensis diverges from 

 P. vitiensis in having a broader black pectoral collar and a 

 much more distinct yellow nuchal collar. 



Male. Yellow supraloral patch absent ; rectrices olive ; 

 throat white, separated from the lemon-yellow of the rest of 

 the underparts by a complete though narrow black collar. 



Pachycephala vitiensis. 



The Ngau Bush Shrike was discovered by Dr. Rayner 

 during the cruise of the ' Herald' (1845-1851) on the island 

 of Ngau (Gray, ' Birds of the Tropical Islands of the Pacific 

 Ocean,' p. 20), and the types are in the British Museum. 



So far as I know, the types are unique. Dr. Gadow refers 

 Pachycephala optata (Hartlaub, Ibis, 1866, p. 172) to this 

 species ; but since the type of Hartlaub's description came 

 from Ovalau there can be no doubt that it belongs to Pachy- 

 cephala neglecta. On the next line but one Dr. Gadow 

 contradicts himself, the Pachycephala vitiensis iemoXe (Finsch 

 and Hartlaub, Fauna Centralpolynesiens, p. 73) which he 

 had just admitted to be that of this species being there 

 denied to be so. The last three references are also wrong. 

 The first of these (Layard, Ibis, 1876, p. 146) relates to a bird 

 which is said to have a yellow throat, and to be only known 

 from Viti Levu, and can therefoi'e only refer to P. graeffii. 

 The second (Layard, Ibis, 1876, p. 392) refers to a bird
