which Prof. Ghigi now increases to twenty-six (!) based 
principally on additions recently made by Mr. Oates*. We 
may venture to express our doubts whether these species, 
some of which are based upon very slight characters, are 
really tenable. 
Prof. Ghigi adds chapters on supposed hybrids between 
the different species, which appear to breed together without 
any difficulty, and on the distribution of these Pheasants 
in China, Burma, and Siam, illustrating his essay by an 
outline map (p. 32). 
33. Grinnell on a new Cow-bird. 
[A new Cow-bird of the genus Molothrus , with a Note on the probable 
relationships of the North American forms. By Joseph Grinnell. Uni¬ 
versity of California Publ. in Zool., viii. p. 275.] 
Mr. Grinnell separates, under the name Molothrus ater 
artemisice, the form of Molothrus found in the “ Upper 
Sonoran and Transition zones of the Great Basin Region of 
the Western United States ” from M. ater of the Eastern 
States, as being somewhat larger and having “a proportionally 
longer and more slender bill, similar to that of M. a. 
obscurus.” Outline drawings are given of the bills of the 
three subspecies. 
34. Hartert on new African Birds. 
[On some recently discovered African Birds. By Ernst Hartert, Ph.D. 
Nov. Zool. xvi. p. 333 (1909).] 
Africa has not yet ceased to produce marvels, at least in 
Bird-life, and these marvels not unfrequently find their way 
to Tring, where there are Ornithologists ready to describe 
them. Dr. Hartert now gives us further information about 
Xenocopsychus ansorgei (from Mossamedes), Graueria vittata 
(from Baraka in Congoland north-west of L. Tanganyika), 
Diaphorophyia graueri (from the forests west of Lake Albert- 
Edward), and Lioptilus rufo-cinctus (from the forest south-east
