FAMILY FRINGILLIDAE 



6l7 



The race floresae of Griscom is based on a single specimen whose dis- 

 tinguishing characters seem to be due to its being in non-adult plum- 

 age. The race lucaris of Bangs, from Costa Rica, also appears to be 

 indistinguishable. Tails tend to be longer in lucaris, but the habits of 

 this bird cause it to be subject to extreme amounts of wear, so that 

 while it might be possible to recognize 2 subspecies eventually, there is 

 not sufficient good material of either this population or of typical hypo- 

 chondriacus to demonstrate the validity of lucaris. Hellmayr (Field 

 Mus. Nat. Hist., Zool. Ser., vol. 13, pt. 11, 1938, p. 613) long ago ex- 

 pressed reservations about lucaris due to specimens not being from 

 comparable seasons.
