Falco vitticaudus Max von Neuwied TYPE 



Beitrag© zur Nat. von Brasilien, 3, 1830, 178. 



No number. Leiden. V/ing 268, tail 171, cu.lmen froia. 

 cere 29.3, depth of maxilla at cere 12, U, tarsus 

 36»0, middle toe minus claw 27»2. Gray tail tip 

 9 mm. ; subterminal black band 60 mm* ; white band 

 70 mm. 



Mounted bird in good state of preservation; eyes vdth 

 bluish white iris. No sex indicated, but probably 

 a male by sex. 



Plumage uniform dark plumbeous, slightly darker than 

 as pictured in Temminck's plate 103. 



This is the first of the three cotypes figured by 



Temminck under the name of " Falco uncinatus Illiger 

 (PI. col. 18° liv. , JB2U, pis. 103, 10^, 115 ^ text). 

 It was sent to Temminck by von weuwied under the MS. 

 name of Falco vitticaudus [ at probably the same time 

 that von Neuwied sent Temminck notes on colors of 

 soft parts (see footnote to 3rd page of text). Six 

 years later von Neuwied issued his ov<ti description 

 vdth the specific reference to plate 103, together 

 with the statement that Temminck's description was 

 a composite of two distinct species. His action 

 necessarily restricts the name uncinatus to the 

 species figured in plates 10 i^ and 115.
