212 Recently Published Ornithological Works. 
J. Stevenson Hamilton, Warden of the Transvaal Game 
Reserve, found the avifauna similar to that of the Transvaal 
Low Country, rather than to that of more northern districts. 
A third paper consists of Notes from Cape Colony by Mr. 
L. E. Taylor, and includes details of the nesting of various 
species, such as Aquila verreauxi and Sula capensis, besides 
observations on the distribution and capture of rare forms. 
Next Mr. A. Ilaagner furnishes us with miscellaneous notes 
from the Transvaal Museum, among which we may remark 
that the writer considers Plectropterus niger inseparable 
from P. yambensis, while he describes as new Bradypterus 
congoensis from West Pondoland, a form akin to B. sylvaticus. 
Easily, Mr. F. Pvm gives a lengthy catalogue of the birds of 
the Kaffrarian frontier near Kingwilliamstown.

[Notes of a Botanist on the Amazon and Andes. By Richard Spruce, 
Ph.D. Edited by A. R. Wallace. 2 vols. London: Macmillan & Co., 
1908.] 
Although the late Dr. Spruce’s Journals (recently edited by 
Dr. Wallace) are, of course, mainly devoted to botany, there 
are occasional references to birds in the narratives of that 
great traveller and collector. Amongst these is an account 
of the migration of the Wood-Ibis ( Tantalus locula/or) as 
observed by Dr. Spruce in several places between the 
Amazon and Orinoco, which is of such interest that we 
venture to reproduce it in this Journal :— 
“ The most remarkable migration that I have myself 
witnessed in South America is that of the great Wood-Ibis 
(Tantalus loculator\ called ‘Jabiru’ in Brazil, ‘Ganau'’ in 
Venezuela, between the Amazon and the Orinoco—a distance 
of from 300 to 500 miles in a straight line, but a thousand 
or more following the courses of the rivers. The migrations 
are so timed that the birds are always on the one river or 
the other when the water is lowest and there is much sandy 
beach exposed, affording the greatest extent of fishing- 
ground. In the years 1853 and 1854, when I was at San 
Carlos del Rio Negro (lat. 1° 53^' S.), I saw them going
