stated that '' Mr. Sharpe has separated the Ceylon Azure 

 Flycatcher from its Indian relative {H. azurea) on account 

 of the absence of the black throat-bar and its much smaller 

 nape-patch/' The species found in Ceylon was given in ray 

 Catalogue (P. Z. S. 1872) under the old name of Myiagra 

 azurea (Bodd.).

Sirs, — The little Sparrow-Hawk which, in Bulletin B.O.C. 

 no. 1. p. xxvii, receives the name of Astur [Scelospizias) hvtleri 

 (G.), if it was to be differentiated from A. jjoiiopsis (Hume), 

 ought certainly, as I now fully admit, to have been described 

 and named by Mr. Rothschild and Mr. Ernst Hartert. Until 

 January 26th I had no idea that I was trespassing on the 

 preserves of the Tring Museum, and that the principal part 

 of Mr. Butler's Nicobar collection was, in fact, Mr. Roth- 

 schild^s property. I wish to apologize to these gentlemen 

 for an inadvertence which I regret, the more so as I under- 

 stand they would willingly have bestowed the same name 

 upon the Hawk in question if satisfied of its distinctness. I 

 am also much indebted to them, inasmuch as Mr. Rothschild 

 has generously ceded two specimens of this valuable bird to 

 the Norwich Museum, where it will be duly honoured in the 

 Raptorial collection. 



Yours, &c.,

Sirs, — Padre Ernesto Schmitz, of Madeira, has recently 

 drawn my attention to the name Thalassidroma castro, 

 given by Harcourt in 1851 to the small square-tailed Petrel 

 generally known as Oceanodroma cryptoleucura (Ridgway) . 



Harcourt's description, which is sufficiently full and clear, 

 can apply only to the above species. 



The name T. castro has been hitherto overlooked ; but, on
