35329. Subadult (sex not indicated). Grecia (on the lower slopes of 

 the Volcan de Poas), Province of Alajuela, Costa Rica. November 30, 

 1864. Collected by Julian Carmiol. 

 Although greater emphasis was obviously placed by Lawrence on No. 

 34818, yet by the rules adopted for this study No. 35329 must be considered 

 a cotype. Lawrence himself wrote the word "Type" upon the label of each 

 specimen.

 den," Saint Andrew's, Grenada Island, Windward Islands, Caribbean 

 Sea. March 16, 1880. Collected by John G. Wells. 

 For reasons unknown, the specimen was not entered into the museum 

 register until October 10, 1895, when it became No. 151129. Unfortunately, 

 this number was not written upon the label, with the result that, on January 

 24, 1896, it was entered again as No. 151807.

 2: 363 (in key) , January 1874. 

 =Empidonax euleri argentinus (Cabanis) . See Wetmore, U.S. Nat. Mus. 

 Bull. 133:335, 1926; Hellmayr, Catalogue of birds of the Americas 

 5:218, 1927. 

 20970. Adult female. Parana, Province of Entre Rios, Argentina. 

 March 1860. Collected by Christopher Wood? Original number 54. 

 Second U.S. Survey of the Rio Parana ( 1859-1860) . 

 Hellmayr (loc. cit., footnote c) believed Parana to be in Paraguay and, 

 making a personal examination of this type, saw in it all the characters of 

 E. e. euleri, the race of Brazil and Paraguay ! 



There is, however, not the least doubt that the specimen came from the 

 Argentine city of Parana (see data for Rhynchotus arcanus Wetmore, p. 4), 

 where, according to Hellmayr himself, the resident form is E. e. argentinus.
