ence in this specimen from the Grey "Wagtail of Europe; and 

 INIr. Cassiu has likewise referred to this species a specimen 

 brought by the United States Expedition from Hakodadi.

Two specimens were preserved from among a number shot on 

 the 6th of August. They all measured about the same. This bird 

 was also collected at Hakodadi by Commodore Perry's Expedition. 



Petrocincla manillensis (Gm.). 



A young male of this tiue Rock-Thrush was killed in August ; 

 it is not an uncommon bird on the rocky peninsula of Hakodadi 

 during summer.

Three specimens of this Thrush, in different states of plumage, 

 were obtained ; they agree with the figures in the ' Fauna Japo- 

 nica.' It seems to be a summer visitor.

My specimen of this fine Thrush was killed at Hakodadi at 

 the end of October; but I observed the bird in considerable 

 numbers in the woods around " Volcano Lake " on the 20th, 

 when they seemed to have but just arrived from the north. 

 Their habits appeared exactly like those of the Missel-Thrush of 

 Europe, and the note of recognition was a similar kind of squeak. 



Mr. Maximovitch places another Thrush, T. daulias, as doubt- 

 ful in his collection*. 



* We have already (Ibis, 1861, p. 2/8, note) recorded our belief in 

 the distinctness of the true Turdus naumanni of Temminck's ' Manuel ' 

 from Turdus fuscatus of Pallas {Turdus naumanni of the 'Fauna Japo- 

 nica'). Capt. Blakiston's specimens of the latter killed in Japan, and of 

 the former obtained at Shanghai, with others in Mr. Gould's collection, 

 aided by the excellent figures and descriptions given of these two oft-con- 

 founded species in the new continuation of Naumann's ' Vogel Deutsch- 

 lands' {confer Ibis, 1862, p. 40), have converted our doubts as to the inac- 

 curacy of referring these two birds to one species into a certainty. The 

 adults of these two Thrushes are very difi'erent, and recognizable at the 

 first glance ; aud, if a little care be taken, there is no difficulty in separating
