of the Genus Tiirdus.

In the Australian region, as I have ah-eady stated, true 

 Turdi are not at present known to occur in New Guinea or 

 Australia. ]Mr. Gray has, however, lately described a Tardus 

 erythropterus from Gilolof ; and a Blackbird occurs in the Sa- 

 moan Islands, which is probably Turdus vanicorensis, Q. etG. 

 In New Caledonia and some of the adjacent islands, a little 

 group of Thrushes is found, which somewhat deviates in struc- 

 ture from the ordinary type, and will probably be ultimately 

 separated from true Turdus. The species of this section at pre- 

 sent known are — Turdus xanthopus, Forster, from New Cale- 

 donia, Turdus vinotinctus {Mei'ula vinitincta, Gould, P.Z.S. 1855, 

 p. 165), from Lord Howe's Island, and T. nestor, Gould, from 

 Norfolk Island. We have, therefore, only five Thrushes in the 

 Australian region. 



In the New World, on the other hand, the genus Turdus is 

 very fully represented. Upwards of forty species are distributed 

 over the different parts of the Northern and Southern continents. 

 In a paper read before the Zoological Society (see P. Z. S. 1859, 

 p. 321 et seq.)y I have given some account of the whole of the 

 members of the family Turdida in the New World, and it will 

 be the less necessary for me to say much about the subject on 

 the present occasion, except so far as is wanted to complete an 

 outline of the general distribution of the genus. 



In the Nearctic region, forming the northern portion of 

 the New World, the following may be taken as restricted to the 

 Atlantic slope : — T.mustelinus,pallasi,fuscescens,swainsoni, and 

 alicice. On the Pacific region opposite, we find T. pallasi re- 

 placed by T. nanus, and T. fuscescens by T. ustulatus, while 

 T. migratorius also occurs, and besides it the well-marked 

 species T. ncevius. On the table-land of Mexico are found pro- 



t See P.Z.S. 1860, p. 350.
