the Sulu Islands. Mr. Hartert describes a desert form of 

 Turtiir communis from Pao^ Persian Gulf, as Tiirtur turtur 

 arenicola, and an additional specimen of Caprimulgus eximius 

 {cf. Ibis, 189.2, p. 279) from Nubia. Finally, E. and CI. Hartert 

 give an account of the "most beautiful collection of Humming- 

 birds that has ever reached Europe.'" This is the series formed 

 by Mr. O. T. Baron, mostly in Ecuador and partly in Mexico 

 and California. The specimens have been all mounted by the 

 collector ^' from the flesh, in the most life-like positions,^' 

 and are accompanied by a number of nests and eggs and 

 Mr. Baron^s field-notes. From Ecuador are examples of 

 8() species, amongst which four [Clialybura intermedia, 

 Eutoxeres baroni, Phaethornis berlepschi, and Eriocnemis 

 evelince) are characterized as new, and two [Metallura atri- 

 gularis and M. baroni), recently described from the same 

 collection by Mr. Salvin, are figured. From Mexico and 

 California there are representatives of 25 species. 



39. Ogilvie-Grant on the Game Birds. 



[Catalogue of the Game Birds {Pterodetes, GallitKe, Opisthocomi, 

 Hemipodii) in the Collection of the British Museum. By W. K. 

 Ogilvie-Grant. London, 1893.] 



The twenty-second volume of the great Catalogue of Birds 

 is now before us, and we will make a few remarks on it as 

 we turn over its pages. It treats of four Orders of Birds, 

 which are easily distinguished by their osseous structure, 

 but are no doubt nearly allied groups — the Pterodetes, 

 Gallinse, Opisthocomi, and Hemipodii, the mass of the 

 species belonging to the great order Gallinse. Mr. Grant 

 recognizes 17 species of Pterodetes, 384- of Gallinse, I of Opis- 

 thocomi, and 24 of Hemipodii. These 426 species are repre- 

 sented in the National Collection by 7021 specimens, of which 

 102 are types. With the exception of Pteroclurm pyrenaicus, 

 which is a barely separable subspecies of P. alchata, the Sand- 

 Grouse are easily distinguishable inter se, and present but slight 

 difficulties. Very different is the case with the true Grouse, 

 which we agree with the author in placing as a distinct family 

 at the head of the Alectoropodous Gallinse. Here are found
