Fringillidie and covering part of the Alaudidae, comprising the species 

 numbered 185 to 394. It well merits the high praise accorded Part I, already 

 noticed,^ maintaining of course the same characteristics as regards scope 

 and method of treatment. The present brochure includes 80 species and 

 130 additional subspecies, of which 20 of the latter are described as new, 

 and manj others are indicated as new and given consecutive numbers but 

 are not formally named. As the number of forms treated is 210, about 

 ten per cent of the whole are characterized as new. Of the genus Loxia 

 three species are recognized, with eight additional subspecies, exclusive 

 of four North American forms mentioned in footnotes, making fifteen 

 recognized forms in all. These include three new subspecies of the L. 

 curvirostra group, — one from Spain, one from Scotland, and another 

 from England. In place of L. curvirostra minor for the common Red 

 Crossbill of northeastern North America Mr. Hartert adopts L. curviros- 

 tra atnericana (Wilson, 181 1), americana Wilson having forty-two years' 

 priority over mijior Brehm (1853) ; but a previous Loxia americana 

 (Gmelin i7S9)"renders Wilson's name untenable. 



In the account of the Alaudida; Otocoris is not yet reached, but in some 

 of the other genera of the family there is a striking array of subspecies, 

 Galerida cristata having twenty-one (plus three doubtful), and_G. theklce 

 eight, and a number of other species of the family have each six to 

 eight or more, indicating the unusual plasticity of the family. — J. A. A. 



Kirtland's Warbler. — Two papers have recently appeared dealing with 

 this rare warbler, one of which, by Prof. Charles C. Adams,"^ treats of its 

 migration route, the other, by Mr. Norman A. Wood,^ of its breeding 

 area. As stated by Mr. Adams : "During the past year more has been 

 added to our knowledge of this bird than during all of the preceding 

 fifty-three years which have elapsed since its discovery." Mr. Adams 

 confines his paper to a consideration of the spring migration records, the 

 species wintering in the Bahamas and breeding in northern Michigan. 

 Dr. L. Stejneger is quoted on the importance of determining the route of 

 this warbler, and the light its discovery would throw upon the problem 

 of "the road by which in past ages part of our fauna entered their pres- 

 ent habitat" (Am. Nat., Vol. XXXIII, 1S99, p. 68, in a review of Butler's 

 ' Birds of Indiana'). Professor Adams considers first, and at some length, 

 the migration routes and breeding area of the Prothonotary Warbler, 

 taking Louck's paper on this species (Bull. Illinois State Lab. Nat. Hist., 

 IV, 1895, pp. 10-38, and Osprey, II, 1898, pp. 99, iii, 129, ) as the basis of 



iPor notice of Part I, see Auk XXI, 1904, pp. 94, 95.
