The wings of seven birds from Matto Grosso vary from 

 205 to 239 mm., while in a series of five males from 

 Colombia the variation ranges from 228 to 249 mm.j and 

 the shape of the wing as shown in a text-fignre is very 

 different in the two extreme cases. Mr. Chapman believes 

 that the short-winged individuals are young birds in their 

 first winter, and that as they grow older the wings, as well 

 as the tail and culmen, increase in length. Ostinops clecu- 

 manns is certainly a species of considerable interest, and 

 deserves further study. 



Christiani on a new Hock-Pipit. 



[Den vestnorske Skterpiber (Ajithus j)etrosus sc/u(pler{, subsp. aov.). 

 Af A. Christiani. Daiisk. Ornith. Forenings Tidsskrift, 1920,

Mr. Christiani here describes a new subspecies of Rock- 

 Pipitj Anthus petrosus schi^lern, from western Norway. The 

 types are from Floro Island near Trondhjem, and Skaer- 

 gaaden near Bergen. The chief distinguishing character is 

 apparently a slight colour-difference in the vinous of the 

 chest. In a further note on the Faroe Island form, A. p. 

 kleinschnidti, described by Dr. Hartert^ Mr. Christiani states 

 that the first observer who pointed out its peculiarities was 

 J. C. H. Fischer (Journ. Ornith. 1861, p. 432), and not 

 Pastor Kleinschmidt as stated by Hartert.

The second and concluding portion of this little book, 

 which is one of Warne's 'Wayside and Woodland^ series, 

 is hardly up to the level of the first volume (c/. Ibis^ April 

 1920). This is, however, chiefiy due to the nature of the 

 subject-matter, and not to any lack of skill in the author. 

 The families treated are those from the Anatidae to the 

 Tetraonidpe, and it is easy to understand that few persons 

 can visit the breeding-haunts of every species, or Avrite with
