interfere on behalf of this bold robber and .expatriator of 
, useful species. Plate iii. is a curious tripartite representation 
sof the Marbled Godwit on its breeding-grounds; and in 
*pl.iv. Mr, Allan Brooks (son: of a former M.B.O.U., we 
believe) gives a pretty illustration of a hybrid between 
Richardson’s Grouse and the Sharp-tailed Grouse. Mr. Wit- 
‘mer Stone (pp. 189-199) has a paper on “‘ Some Changes 
in ‘the Current Generic Names of North-American Birds” ; 
the changes in many cases upsetting the nomenclature 
familiar to us. For the full advantage to be derived from 
this paper, it should be studied along with Dr. J. A. Allen’s 
“The First Species Rule for Determining Types of Genera— 
How it works in Ornithology” (Science, n. s. xxv. pp. 546- 
554), and “The Types of the North-American Genera of 
Birds” (Bull. Am. Mus. N. H. xxii. pp. 279-3884).—H. 8S.

This number contains only three principal papers, the first 
by Capt. B. R. Horsbrugh on Otis cerulescens (pl.), the second 
by Mr. R. Phillipps giving further notes on the Regent 
Bird, and the third by Mr. Meade-Waldo entitled “‘ Some 
Remarks on Birds seen during the Cruise of the ‘ Valhalla, 
R.Y.S.” No special remarks seem necessary, but attention 
may be drawn to the picture of several specimens of 
‘Abbott’s Ibis on Aldabra, accompanying the last article.

[Morfologia dello sterno degli Uccelli Italiani d. prof. dott. Enrico 
Balducci, Roma, 1906. (Boll. Soc. Zool. Ital. pp. 10.) | 
Prof. Balducci is planning the preparation of a general 
work on the sternum in Italian Birds, which will be useful 
‘when complete. The present fragment relates only to the 
Owls, and contains mainly: measurements ‘and outline figures 
of the sterna of the ten Italian species.
