Ridgway on New Forms of Picidae. 1 — Mr. Ridgway here describes 

 11 new subspecies of American Woodpeckers and proposes a new genus, 

 Bdanosphyra, for the Melanerpes formicivorus group. Most of the sub- 

 species are tropical, but the following are North American: (1) Colaptes 

 auratus borealis, the large form of the Canadian and Hudsonian zones, 

 based wholly on size. (2) Colaptes chrysoides mearnsi, from " Arizona, 

 extreme southeastern California and northern Lower California." C. c. 

 brunnescens Anthony, omitted from the last A. O. IT. Check-List, is also 

 here reinstated. (3) Centurus uropygialis brewsteri, from southern Lower 

 California. (4) Phlceotomus pileatus floridanus, from peninsular Florida. 

 This, with the recently described P. p. picinus Bangs, 2 here also recognized, 

 gives four subspecies of P. pileatus, and adds two to the last A. O. U. 

 Check-List. All are based mainly on differences in size, and on the fact 

 that corresponding subspecies are recognized for the corresponding areas 

 in the Dryobates villosus and D. pubescens groups. — J. A. A. 



Oberholser on the Flycatchers of the Genera Hypothymis and 

 Cyanonympha. 3 — The genus Hypothymis consists, as here recognized, 

 of 4 species and 16 additional subspecies, of which 15 are subspecies of 

 H. azurea, for the most part insular forms; 11 of the subspecies are 

 here first distinguished; most of the others were originally described as 

 species. The group ranges from southern India to the Philippines, Suma- 

 tra, Borneo, Celebes, and Java, including the numerous smaller outlying 

 islands. The new genus Cyanonympha consists of Hypothymis super- 

 ciliaris and its subspecies samarensis, from the southern Phillippines. 

 Keys are given to the species and subspecies, and tables of measurements 

 of large series of specimens of many of the forms recognized. The mono- 

 graph is based mainly on the collections made by Dr. W. L. Abbott, with 

 other material in the U. S. National Museum, numbering altogether 

 (including a few borrowed) 205 specimens. — J. A. A.
