slightly granular. In form they are long elliptical with measurements 

 of 25.8 X 18.6 and 26.5 X 19.1 mm. In another set from the Mazaruni 

 River, Guyana, collected October 6, 1936, the 2 eggs are cream-buff, 

 very faintly granular and long elliptical in form, with measurements 

 of 26.1 X 18.8 and 27.9 X 19.3 mm. These all average slightly smaller 

 than several from Cuba and Jamaica in the National Museum collec- 

 tions. The latter range from 27.2-28.0x20.6-21.6 mm. 

 In Bocas del Toro this species is called paloma chocolate.
