 minuta, Leimonites tcmmincki, Acroceplialus turdoides, Nycticorax 

 griseus, Puffinus major, Columha livia, Turtur auritus, Corvus

 Heematopus ostralegus, Bernicla hrenta, B. rufcollis, Himantopus 

 candidus, Limnocinclus pectoralis, Tryngites rufescens, Limicola 

 pygmoiu, Herodias garzetta, and Procellaria glacialis. Though 

 not responsible for the actual coinage of many of the generic 

 names quoted above, IMr, Gould seems only too ready to make 

 them pass current. We believe that it would not be possible 

 to indicate any precise characters by which several of the above- 

 mentioned genera may be distinguished.

4. Descrip)tion of a supposed new species of Pigeon. Ann. & 

 Mag. N. H. ser. 4, vol. v. p. 62 (1870). 



A new generic name, Otidiphaps, is proposed for a singular 

 Pigeon, supposed to be from '^ one of the islands of the Eastern 

 Archipelago or New Guinea,^^ and the species is called 0. nobilis. 

 Though the bill is stated to be longer than the head, straight and 

 Plover-like, and not toothed, Mr. Gould expresses his opinion 

 that this form is allied to Didunculus [cf. P. Z. S. 1870, p. 4).

 4, vol. vi. p. 224 (1870).

 Fernandez group of Islands. Ann. N. H. ser. 4, vol. vi.

 The species here described is called Eustephanus leyboldi, 

 specimens having been procured by Mr. Leybold of Santiago, 

 Chili, from the little island of Mas-afuera {of Sclater, anteu, 

 p. 178 et seq.).
