TYPE SPECIMENS OF BIRDS 53 



=Falco sparverius loquaculus (Riley) , fide Friedmann (ms) . 

 169029. Adult male. Isabel II, Vieques Island, Caribbean Sea east of 

 Puerto Rico. February 8, 1899. Collected by Arthur B. Baker. 

 Original number 91. Received from the U.S. Fish Commission. 

 Falco sparverius aequatorialis Mearns 

 Auk 9 (3) : 269, 1892. 

 101309. Subadult male. "Guayaquil, Ecuador," error="the interior of 

 Ecuador" [fide Jones, in epist. of November 11, 1884). Entered into 

 the museum register on January 5, 1885. Received from William H. 

 Jones, who acquired it, with other birds, from "Mr. Cartright Agt. 

 P.S.N. Co. Guayaquil as a gift" {in epist. cit.) . 

 While Mearns intended to base his description on two cotypes (male and 

 female). Chapman (Bull. Amer. Mus. Nat. Hist. 34:376-377, 1915) has 

 shown that the female. No. 67349 from "Ecuador," is in fact an example of 

 F. s. caucae. 

 Tinminculus sparverius var. Australis Ridgway 



Proc. Acad. Nat. Sci. Philadelphia, p. 149, footnote (not earlier than 

 December 27) , 1870 (=1871 ? ) . 

 =Falco sparverius eidos Peters. See Peters, Checklist of birds of the 



world 1:305, 1931. 

 50942. Adult female. Brazil. Entered into the museum register on 



May 5, 1868. Collected by Frederico de Albuquerque. 

 Ridgway 's first use of the name australis was essentially a mere renaming 

 of Falco gracilis Swainson 1838, not Lesson 1830, nor Temminck 1821, but 

 in Baird, Brewer, and Ridgway (History of North American birds 3: 166, 

 1874) it appeared again with a formal description and the listing of three 

 specimens that might stand as cotypes. Richmond was accordingly led to 

 treat Ridgway's australis as independent of Swainson's gracilis and set aside 

 No. 20937, the first-named, as the type. 



A study of the three specimens is interesting. The first. No. 20937, was 

 taken in September 1860, not on the Parana as stated, but in Uruguay or 

 on the Uruguay River, and is a representative of F, s. cinnamominus Swain- 

 son (or, strictly speaking, cinnamoninus > eidos) . No. 50942 is from Bra- 

 zil and is F. s. eidos Peters. No. 16570, from Bogota, is F. s. intermedins 

 Cory. 



I am in complete agreement with Cory (Field Mus. Nat. Hist. Orn. Ser. 

 1:317 [footnote], 319, 1915) that australis of Ridgway should be held to 

 have the same type specimen as gracilis of Swainson, but Ridgway's peculiar 

 treatment of his name could lend legalistic grounds to one who, like Rich- 

 mond, cared to take a different view. Since Ridgway's series was composite, 

 a reviser could select either No. 20937 or No. 16570 as the type, thus making 

 Peters's name eidos (new name for australis Ridgway, not Hombron and 

 Jacquinot 1841, nor Gmelin 1788) a mere synonym of either cinnamominus 

 or intermedins, and leaving the bird of Bahia again without a valid name.
