284 Recently published Ornithological Works. 



Mr. Harting gives us here the substance of one of the 

 '' Davis Lectures/^ which he delivered at the Zoological So- 

 ciety's Gardens on June 24th last year. 



43. Lawrence on a new Chrysotis. 



[Description of a new Species of Parrot of the Genus Chrysotis, from 

 the Island of Dominica. By George N. Lawrence. Proc. U.S. Nat. Mus. 

 vol. ii. p. 254.] 



The species is named C. nichollsi, after Dr. Nicholls, who 

 discovered it, and belongs to the group of C. bouqueti. The 

 existence of a second large Chrysotis in Dominica is very 

 singular. 



44. Nehring on Prehistoric Bone-deposits. 



[Die Raubvogel und die prJihistorischen Knoclienlager. Von Dr. A. 

 Nehring. Corresp.-Blatt der deutschen GeseU. f. Anth., Eth. u. Urge-' 

 schichte, 1879, p. 57.] 



Dr. Nehring discusses the question how far birds of prey, 

 and especially Owls, can be considered to have contributed to 

 the formation of bone-deposits in caverns. He comes to the 

 conclusion that they have played a not unimportant part in 

 this matter. 



45. Reinhardt on Loxia leucoptera. 



[Er Loxia leucoptera, Gm., virkelig trufien i Danmark ? . Af J. Rein- 

 hardt. Vidensk. Med. Kjobenhavn, 1881.] 



Prof. Reinhardt discusses the four alleged occurrences of 

 the North- American Loxia leucoptera in Denmark. He comes 

 to the conclusion that two of these birds are really L. bifas- 

 ciata, and that the other two cases cannot be depended upon. 



46. Reinhardt on Lanius major. 



[Om Lanius major, Pall, og dens Forekomst her i Landet. Af J. Rein- 

 hardt. Vidensk. Med. Kjobenhavn, 1879-80.] 



Two examples of Lanius major of Pallas occurred in Den- 

 mark in 1874 and 1875, and are now in the collection of 

 Danish birds in the ]VIuseum of Copenhagen. Prof. Rein- 

 hardt discusses at some length the relationship of this form 

 to the nearly allied L. excubitor.
