 Thryophilus ruf albus castanonotiis Ridgway 



Proc. Boston Soc. Nat. Hist. 23: 386, March 1888. 

 =:Thryothorus rufalbus castanonotiis (Ridgway). See ileilmayr, Cata- 

 logue of birds of the Americas 7: 172, 173, 1934. 

 32694. Adult male. "Cote ferme"::=Panama. Entered into the museum 

 register on Mar. 18, 1864. Received from the Maison Verreaux, Paris. 

 Ridgway's Thryophilus rufalbus castanonotus was a mere substitute name 

 for Thryophilus rufalbus, var. rufalbus Baird (Revievv' of American birds 

 1: 128, 129, 1864), not T[hriot.horus]. rufalbus Lafresnaye, 1845. Ridgway 

 gave no description of his own, but instead, a clear indication to Baird's, 

 and we are therefore compelled to consider Baird's specimens the types of 

 Ridgway's new name. 



Baird's series consisted of four specimens, of which one. No. 32692, a 

 male from Bogota, is a representative of Thryothorus rufalbus minlosi (von 

 Berlepsch) , and accordingly not to be listed here. Two others, a male and 

 a female from the "Panama R.R.," each with original number 93, are pre- 

 sumably now in the American Museum of Natural History as part of the 

 Lawrence Collection. 



Thryothorus rufallius castanonotus Ridgway 

 Proc. U.S. Nat. Mus. 10: 508, Aug. 6, 1888. 

 =Thryothorus rufalbus castanonotus (Ridgway), March 1888, fide 



Deignan (MS.). 

 81783. Adult female. Angostura, Province of Cartago, Costa Rica. 

 July 1875. Collected by Jose C. Zeledon. Original number 732. 

 Received from Robert Ridgway, of whose private collection it once 

 formed part. 

 This name is accompanied by a formal description, with a reference to No. 

 81783 as "type." Since No. 81783 was not a cotype of Thryophilus rufalbus 

 castanonotus Ridgway, March 1888 {vide supra), Thryothorus rufalbus 

 castanonotus Ridgway, Aug. 6, 1888, must be considered an entirely new 

 name, which only accidentally happens to ai)ply to the same race as its 

 earlier homonym. 

 Thryothorus brunncus Lawrence 



Ann. Lye. Nat. Hist. New York 8: 178 (not earlier than Oct. 23), 1865. 

 =Thryothorus thoracicus thoracicus Salvin. See Hellmayr, Catalogue of 

 birds of the Americas 7: 175, 176, 1934.
