FiNSCH. — New Zealand Birds. 209 



Himantopus novce-zealandice, Gould. 



This is the iinicolour black one, and the same as H. melas, Homb. and 

 Jacq. The pied stilt, therefore, named H. novce-zealandice by Capt. Hutton, 

 ("Cat. Birds N.Z.," p. 29), will be nothing as a state of the black species, 

 whereas H. novce-zealandice, Potts {Trans. N.Z. Inst., Vol. II., p. 70), is pro- 

 bably H. leucocephalus, Gould. 



Trin^a canutus, Hutton (" Cat. Birds IST.Z.," p. 30). 



This, I expect, will turn out to be Tr. crassirostris, Temm. and Schleg, 

 (Faun, jap, pi. 64), the larger eastern representative of canutus. 



Ocydronius troglodytes, Gml. ; 0. australis, Finsch, " Journ. f. Orn." 

 1870, p. 352. 



This species has been hitherto confused with australis, Sparrm. I shall 

 treat of all the New Zealand Ocydronii (four species) extensively in my 

 paper, with full descriptions and their corrected synonymy. 0. troglodytes is 

 the largest, and easily recognizable by its olive brownish-yellow colouration, 

 and is the bird figured by Gray (" Ereb. and Terr." t. 14). 



Ocydromus australis, Sparrm. 



Considerably smaller, and of an olive, rufescent-brown, ground colour ; 

 tail feathers barred regularly with black and rufous brown. 

 I received one specimen from Dr. Haast. 



Ocydromus fuscus, Du Bus. 



I examined one of the types of 0. nigricans, Bull. There can be no doubt 

 of its identity, as I declared already. 



Rallus pectoralis. Less. 



Specimens from the Okarita Lagoon, sent by Dr. Haast, agree perfectly 

 with others from Australia, the Pelew and Samoa Islands. 



Mr. Potts' new R. pictus (Ibis, 1872, p. 36) based upon a specimen from 

 the same locality, has no claim as a species. 



Lestris parasitica, Hutton (" Cat. Birds N.Z.," p. 40) 

 Is apparently not this species, but L. longicaudatus, Briss. (Buffoni, Boie 

 — spinicauda. Hardy nee Layard.) 



Larus novce-hollandice, Steph. (Z. scopidinus, Finsch, Hutton, Potts.) 



I shall describe all the plumages of this very confused species and settle 



the synonymy. 



The larger L. jamesoni, Gould, is not yet separated exactly, although 



there exists a great variety in size, especially in the bill. 



Larus pomare, Bruch. " Journ. f Orn.," 1855, p. 285, nee 1855, p. 103. 

 To this species belong L. melanorhynchus. Bull. ; L. bulleri et jamesoni, 



B 1
