63. Hellmayr on the Nuthatches. 



[Genera Avium, conducted by P. Wytsnian. Part XVI. Sittidae, by 

 C. E. Hellmayr, Brussels, 1911.] 



In tliis essay four genera of the Family of Sittidse — Sitta, 

 Callisitta, Neositta, and Daphceno sitta are recognised. Under 

 Sitta 46 forms are enumerated, but most of these are sub- 

 species. Our familiar Nuthatch is called Sitta europcea 

 britannica. Sitta ivhiteheadi, of Corsica, is placed as a sub- 

 species of Sitta canadensis. We admit that the two forms 

 are closely allied, but we think that the Corsican bird ought 

 to stand as a separate species. 



A nicely drawn plate represents the beautiful Callisitta 

 formosa and contains details of other species. 



64. Hellmayr on the Regulidse. 



[Genera Avium, conducted by P. Wytsman. Part XVII. Regulidae, 

 by C. E. Hellmayr. Brussels, 1911.] 



In the Family Kegulidfe the author includes four genera — > 

 Leptopacile, Reyidus, LopJiobasileus, and Polioptila. As 

 regards the first three of these we suppose there is 

 no doubt that they are near allies, but whether Polioptila 

 should be assigned to the Regulidse is, we think, a little 

 doubtful. Its distribution is so utterly different from that 

 of the other genera. Herr Hellmayr catalogues 25 forms 

 of Polioptila, but the majority of these are subspecies. lu 

 a good plate accompanying this part are figures of 

 Polioptila schistuceigula and Reyulus tristis. 



65. Hellmayr on neiv or rare Birds fro^n Peru. 



[Ueber neue imd seltene Vogel aus Sudperu. Von C. E. Hellmayr. 

 Verb. Oru. Ges. Bay. xii. Heft i.] 



Herr Hellmayr describes, in his usual careful and accurate 

 manner, some new or rare birds from a collection made by 

 jMessrs. H. and C. Watkins at or near Carabaya, in Southern 

 Peru. Two new species are Automolus watkinsi and Tham- 

 nophilus mareopatcR. Three specimens of the rare Coerebine 

 form Oreomanes fraseri were in the collection. They were
