BIRDS OF NOETH AND MIDDLE AMERICA. 891 



rump; wings fuscous, the quills, greater coverts, and primary coverts 

 edged with brownish gray, the outer web of outermost primary nearly 

 all white; lesser wing-coverts and upper tail-coverts cinnamonieous; 

 tail black, the two middle feathers fuscous, margined with brownish 

 gra}", the exterior web of outermost pair of rectrices edged with 

 white; occiput, cervix, and sides of neck pinkish cinnamonieous; 

 crown, ''horns," lores, cheeks, and jugular crescent black; auriculars 

 yellowish white washed with grayish; forehead, superciliary stripe, 

 and postocular streak yellowish white; chin and throat pale primrose 

 yellow; flanks, thighs, and sides of breast and of body light bro\vnish 

 cinnamon; rest of lower parts, including lining of wings, white. 



''This new race is in color very similar to Otocoris alpestris leuco- 

 laema, but is more grayish above, at least when in good plumage; 

 and has the eyebrow usuall}^ more j^ellowish; furthermore, the 

 greatly inferior size of Otocoris a. enertera distinguishes it at once. 

 From Otocoris alpestris actia, whose range it approaches most closely, 

 it differs very much more than from either Otocoris a. ammopliila or 

 0. a. leucolaema, being strikingly paler and more grayish throughout, 

 as well as somewhat smaller. 



"The t}^e specimen above described still retains some of the 

 brownish gray edgings of crown, jugulum, and cervix, but otherwise 

 represents the perfect breeding plumage. Wlien badly worn, 0. a. 

 enertera looks more like 0. a. ammopliila than when in fresh condi- 

 tion, though it is still more grayish and pinkish above, and of course 

 smaller. Otocoris alpestis enertera appears to be non-migratory; and 

 its range, so far as known, extends in Lower California from Santa 

 Rosalia Bay to the neighborhood of Magdalena Bay."

Page 335: Famil}- Tyrannidae. Since that portion of the present 

 volume covering the Tyrannid?e was printed several important papers " 

 by Count von Berlepsch, bearing exclusively or in part on this group 

 of birds, have been published in the Proceedings of the Fourth Inter- 

 national Ornithological Congress (date of publication, Februar}^, 1907), 

 citations from which are here given in regular order.

 Fourth International Ornithological Congress, 1905 (published February, 1907). pp. 

 372-448. (An elaborate and most valuable paper, which the author of the present 

 work is very sorry not to have seen earlier. Count von Berlepsch includes in Elaenia 

 the genera Myiopagis and Elainopsis.)
