general colouring, and to Trihonyx in the structure of its feet ; while in the feebleness of its 

 ■s and the structure of its tail it differs from both. (See page 192.) The recent discovery 



win: 



therefore, in the South Island, of an example of Tribonyx mortieri which has been brought to 

 England, and is now living in the Zoological Society's Gardens, is a very interesting fact in 



geographic natural history. 



The former acquisition by the Society of a similar bird, in July 1867, led to the discovery by 

 Dr. Sclater that the species figured and described by Mr. Gould in his ' Birds of Australia ' under 

 that name was not the true Trihonyx mortieri of Du Bus (Bull. Acad. Sc. Brux. vii. p. 214), 

 but a distinct bird, characterized by its smaller size, and by the absence of white stripes on the 

 wing-coverts. Dr. Sclater accordingly proposed the name of Trihonyx gouldi for the latter 

 species (Ann. N. H. 1867, xx. p. 122), and gave the following distinguishing characters for 

 T. mortieri:

For the purpose of illustrating the difference in the plumage, an excellent woodcut of this 

 species was given in the 'Proceedings' of the Zoological Society (1867, p. 816); and by the kind 

 permission of the Publication Committee I am allowed the opportunity of reproducing it here. 



The bird now in the " Gardens " was brought home (with other birds from New Zealand)
