Thryophilus taenioptera [sic^ Ridgway 

 Proc. U.S. Nat. Mus. 10: 518, Aug. 6, 1888. 

 :=Thryothorus leucotis taeniopterus (Ridgway) . See Giiscom and Green- 

 way, Bull. Mus. Comp. Zool. 87: 301, 1941.

 of the Rio Tapajos), State of Para, Brazil. June 29, 1887. Collected 

 by Clarence B. Riker. Original number 4.

 Thryothorus superciliaris Lawrence 



Ann. Lye. Nat. Hist. New York 9(7): 235, June 1869. 

 =ThryothoTus superciliaris superciliaris Lawrence. See Hellmayr, Cata- 

 logue of birds of the Americas 7 : 167, 1934. 

 54099 (not 54100). Adult (sex not indicated). Puna Island (in the Gulf 

 of Guayaquil) , Province of Guayas, Ecuador. Entered into the museum 

 register on February 15, 1869. Collected by J. F. Reeve. 

 In the original description, Lawrence stated that he had seen three speci- 

 mens, and that No. 54100 was the type. No. 54100 is now in the American 

 Museum of Natural History, where it is No. 39409; on the reverse side of 

 its label, m Lawrence's handwriting, is the word "Typical." On the reverse 

 side of the label of our No. 54099, again in Lawrence's hand, is the word 

 "Type." It seems certain, then, that the skin in Washington is the true type, 

 and that the number "54100" appeared in print as the result of a lapsus 

 calami.
