This species is quite distinct from any hitherto described. 

 It is smaller than even O. thoracicus, to whicii it is perhaps 

 most nearly allied. The white throat and belly, the strongly 

 marked flanks, together with the deep rufous colour which 

 encircles the whole of the anterior part of the body, neck, and 

 head, r*ender it a conspicuous species. 



XXXVII. — Letters, Announcements, &^c. 

 The following letters, addressed " To the Editor of ' The 

 Ibis,^ " have been received : — 



Sir, — I beg leave to oflFer the following short notes on several 

 species of birds found in Corsica as an appendix to Mr. C. 

 B. Wharton's paper on the ornithology of that island {antea, 

 p. 17). I also add the names of seven species which came 

 under my notice in the years 1865-66, as well as seven extra 

 species observed in 1875. 



The only general observation I should like to make is that 

 a considerable proportion of the individuals of the different 

 gpecies seems as though they only made Corsica a temporary 

 halting-place on their journey northwards; and I feel con- 

 fident that if a really perfect and trustworthy list of Corsican 

 birds could be noted, say during a term of three or more years, 

 the number of species would be found to be comparatively 

 limited, and that of the spring migrants bear but a small pro- 

 portion to the entire list. In the case of several species, both 

 Mr. C. B. Wharton and myself would come across a con- 

 siderable number of individual birds during a few consecutive 

 days, after Avhich they were suddenly lost sight of. Could 

 any ornithologist be found who would furnish us with a list, 

 such as I have already csuggested, of the birds of Corsica and 

 Sardinia, coupled with a very accurate record of dates, eleva-
