remaining pages of the present number of Dr. Harterfs 

 work, are perhaps three of the most difficult Passerine groups 

 in the whole Palsearctic Ornis, and must have cost the ener- 

 getic author much time and trouble, although they have 

 been lately well monographed by Mr. Hellmayr*. Of Cer- 

 thiidse Dr. Hartert enumerates 19 palsearctic species and 

 subspecies ; of Tichodroma, the second palsearctic genus of 

 this Family, happily only one, although several attempts 

 have been made to separate the local forms. Of Certhia 

 4 new subspecies are described and designated C. familiaris 

 corsa (Corsica), C. f. bianchii (Kansu), C. f. tianschanica 

 (Tianshan), and C. brachydactyla ultramontana (S. Europe). 

 Thus while Mr. Dresser allows only 2 Palsearctic species of 

 Certhia Dr. Hartert gives us 19 separable forms. This is 

 indeed a revolution ! 



Of the Nuthatches only one genus (Sitta) occurs within 

 the Pakearctic area, but the local forms, as we all know, are 

 numerous : Dr. Hartert makes 24 of them — 7 species and 

 17 subspecies. Sitta europcea is divided into 13 subspecies, 

 among which our familiar bird figures as Sitta europcea 

 britannica. S. e. levantina is a new subspecies from Asia 

 Minor and Palestine. What has always been taken for a 

 very distinct species — Sitta whiteheadi of Corsica — is now 

 degraded into a subspecies of Sitta canadensis. This is cpuite 

 a new view to us, but Dr. Hartert has, no doubt, carefully 

 considered the question. It is most remarkable that two 

 birds from such widely separated localities should be so nearly 

 related. 



The Paridse, which come next, are not quite finished in 

 this Part of the work, so we will defer our remarks upon 

 them until the publication of Part IY.
