Recently published Ornithological Works. 645 



Anyone who has worked at the birds of America — and, 

 alas ! the number who are now so engaged among our Britisli 

 ornithologists is all too few — well knows how indispensable 

 Mr. Ridgway's volumes are^ and will welcome the appearance 

 of the present volume^ and will join with us in hoping that 

 lie may be spared to complete the work. 



Salvadori o?i a Forgotten Paper by Bonaparte. 



[Intorno ad un lavoro del Principe Carlo Luciano Bonaparte. Nota 

 del Socio T. Salvadori. Atti Accad. Sci. Torino, vol. xlix. 1914, 

 pp. 447-451.] 



In this short note Salvadori draws attention to a paper by 

 Bonaparte, which contains a number of new generic names, 

 and which appears to have escaped, or partially escaped, the 

 notice of bibliographers. The title of the paper is 

 " Parallelismo fra le tribu dei Cantori Fissirostri e quelle 

 dei Volucri hianti et dei Nothurni orvero insidenti/' and it 

 was published in the ' Rivista Contemporanea/ vol. ix., 

 February 1857, pp. 209-217. 



The names of the new genera introduced are Hemicecrops, 

 P7-istoptera, and Taperu for certain species of Swallows; of 

 these, the last-mentioned was previously used by Thunberg 

 and is therefore invalid. For members of the family 

 Cypselidse, Achantylops and Pallenia are proposed ; the first 

 has no species assigned to it, and can therefore not be made 

 use of under any circumstances. Finally, Ramphaoratiis 

 and Capripeda are suggested for certain members of the 

 family Caprimulgidse, 



Stresemann on the Edible-nest -producing Swift. 



[Was ist Collocalia fudphcKja (Tliunb.) ? Von Erwiu Stresemann. 

 Verhaudl. Ornith. Ges. Eayern, xii. 1014, pp. 1-12.] 



Mr. Stresemann has discovered, with the aid of Mr. Bartels, 

 in Java, that there are two distinct but closely allied species 

 of Collocalia existing side by side in that island. He com- 

 pares this state of things with Parus palustris and P. atri- 

 capillus, Certhia familiaris and C. brachydactyla, which, 

 though quite distinct species, are difficult to distinguish.
