ORTALIS VETULA PALLIDIVENTBIS Ridgwar

Adult (sexes alike). — Similar to the adult of Ortalis vetula vetula but 

 paler below, the abdomen dull whitish isabelline, darkening on the sides, 

 flanks, thighs, and under tail coverts to isabelline; the breast less olive- 

 brown, more ashy olive; and the tips of the rectrices not pure white but 

 washed with isabelline to pale buffy. 



"This designation appears to be proper, inasmuch as the name leucogastra was 

 originally proposed as a new name for Penelope albiventer Lesson from Realejo, 

 Nicaragua (Proc. Zool. Soc. London, 1843, 105).
