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

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 Figure 49.—Wedge-tailed Grass-finch, Pinzon Yerberero Coliacunado, Emberi- zoides herbicola Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Wetmore, Alexander, 1886-1978.
