at Torquay, who has numerous specimens, assures me that he 

 can find it on Dartmoor throughout tlie year. 



Again, as regards the Rock Martin {Cotyle rupestris, Boie), 

 though I am aware that writers on ornithology put it down 

 (perhaps from analogy) as a migrant, I have not been able to 

 ascertain any satisfactory proof of this habit. Mr. Moggridge 

 bears testimony to its winter residence at Mentone ; my friend 

 Mr. Simpson assures me it spends the winter where it breeds, at 

 Missolonghi in Northern Greece. I have seen it myself all the 

 winter in the rocky gorges of the Morea, among the hills and 

 rocks of Judsea, and throughout the Atlas range of North Africa, 

 where I have noted it during every month from September to 

 July*. On the other hand, I have been unable to ascertain satis- 

 factorily a single locality where it is found only in summer. I 

 trust that your world-wide contributors will soon be able to clear 

 up these and all other doubtful points in the history of our 

 bird-fauna. I am. Sir, yours &c.,

To the Editor of ' The Ibis: 



SiR^ — I send you the following note on Accipiter gularis of 

 the 'Fauna Japonica,' and Accipiter virgatus of Temmiuck. 



In Mr. Swinhoe's interesting paper on the Ornithology of 

 Formosa, published in the last Number of ' The Ibis,' reference 

 is made, in page 213, to an opinion which I expressed that the 

 above two species might prove identical. 



I have subsequently had the opportunity of consulting Prof. 

 Schlegel's description of the two species in the fii-st part of his 

 valuable Catalogue of Birds in the Leyden Museum, and, after 

 doing so, I have very little doubt that this opinion is erroneous, 

 and that the learned Professor is correct in considering the two 

 species as distinct. 



The specimen obtained by Mr. Swinhoe in Formosa, being 

 immature, cannot be identified with certainty by any distinctive 

 marks of coloration in plumage, these being only found in the 



* It is also a permanent resident on the Rock of Gibraltar. See our 

 remarks on this bird in "Vacation Tourists," 18()1, p. 205. — Ed.
