The present family is formed to receive the genus Nestor (5 

 sp.), confined to New Zealand and Norfolk Island. Its affinities 

 are doubtful, but it appears to have relations with the American 

 Conuridae and the Australian Trichoglossidse. With it is placed

 which however very little is known.

 Parrot of New Zealand, Stringops habroptilus (Plate XIII. 

 Vol .1. p. 455). An allied species is said to inhabit the Chatham 

 Islands, if not now extinct. 



General Remarks on the Distribution of the Psittaci.

 distinct families, yet they form so well marked and natural a 

 group, and are so widely separated from all other birds, that 

 we may best discuss their peculiarities of geographical distri- 

 bution by treating them as a whole. By the preceding 

 enumeration we find that there are about 38p h species of known 

 parrots, which are divided into 52 t} genera. They are pre-

 a considerable distance into the temperate zone, these are
