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 Caw-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 

 artemisia, 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), 

 Diaphoroj/h'jia graueri (from the forests west of Lake Albert- 

 Edward), and Lioptilus rufo-cinctus (from the forest south-east
