TYPE SPECIMENS OF BIRDS 237 



Dendrocolaptes certhia ridgwayi Hellmayr 

 Nov. Zool. 12 (2) : 282, September 20, 1905. 

 =Dendrocolaptes certhia ridgwayi Hellmayr, but see Zimmer, Amer. Mus. 



Nov. 753:2-4, 1934. 

 112283. Adult male. Diaraantina (near Santarem and east of the mouth 

 of the Rio Tapajos), State of Para, Brazil. July 11, 1887. Collected 

 by Clarence B, Riker. 

 Dendrocolaptes certhia ridgwayi is a new name for Dendrocolaptes ob- 

 soletus Ridgway, not D. ohsoletus Lichtenstein, 1820, and has the same type 

 specimen. Hellmayr (Catalogue of Birds of the Americas 4: 259, 1925) 

 synonymized his name with Dendrocolaptes certhia concolor von Pelzeln, 

 but Zimmer {loc. cit.) has shown that specimens from the vicinity of Dia- 

 mantina are in fact D. c. concolor X medius. Thus, while the intergradient 

 population is perhaps unworthy of a special designation, yet for convenience 

 it may be known by Hellmayr's name. 

 Dendrocolaptes validus costaricensis Ridgway 

 Proc. Biol. Soc. Washington 22: 73, April 17, 1909. 

 =Dendrocolaptes picumnus costaricensis Ridgway. See Peters, Checklist 



of birds of the world 7 : 34, 1951. 

 210393. Adult male. Laguaria ("a point high up in the Dota Moun- 

 tains . . . south of Santa Maria [de Dota] and El Copey, and probably 

 nearly 10,000 feet above the sea," fide Carriker, Ann. Carnegie Mus. 

 6: 345, 1910), Province of San Jose, Costa Rica. June 4, 1908. Col- 

 lected by Francisco Basulto. [U.S. National] Museum-Zeledon Expedi- 

 tion (1908). 

 Carriker {loc. cit.) gives the type locality as "Lagunaria," but all of 

 Basulto's original labels distinctly spell the word as I have done above.
