Pendulinus xanthomus 



Var. : Dubusii Reed from J, Verreaux 



Dubois under the LiS name of 



Type Xanthomus Dubusii. 



Loc. Panama 7108 



In the Dubois handwritten register this specimen and 

 7108b vrere originally listed as from "Cote ferme" - 

 this crossed out and "Isthmus de Panama" substituted. 

 A footnote remark says "it is characterized 

 especially by the black spots on the back". 



Mounted bird in good condition; yellow eyes; plumage 

 v/om with resultant narrov/ edgings to v;ings. I am 

 inclined to believe it a female - even though 

 catalogued as "d" - this because of the slightly im- 

 pure yellow of back & upper rump and rusty tinge to 

 ends of primaries. 



Wing coverts basally extensively black; outer primaries 

 edged v;ith viiite only beneath primary coverts (con- 

 cealed). Greater coverts and secondaries very 

 narro^vly edged with v/hite - this latter condition, in 

 part at least, due to wear. 



7108b (w.89) In the accompanying bird - a $ so marked 

 wear is even more evident, but traces of black back 

 spotting remain. Otherwise similar to type save that 

 wing coverts (lesser <St middlej have only traces of 

 black. Brussels July 13, 1939* 



Dubus has both birds marked as "type" but he describes 

 only the "male" and his wing measurement (exactly 

 mine) corresponds to only 1 specimen.
