 Pisorhina choliba (Psubsp.) Berlepsch & Hartert, p. 116. 



Not common, but noted at all points visited along the Orinoco. 



Eye lemon yellow; bill greyish horn color; feet dusky brownish. 



A nest of this species containing a single fresh egg was found 

 at Quiribana de Caicara, April 6, 1898. The nest was a natural hollow 

 in a limb of a scrub oak, about one metre and a half from the ground. 

 No nesting material had been taken into the nest cavity. A second 

 nest similarly placed was found at Agua Salada de Ciudad Bolivar, 

 April 1 8, 1907. This nest contained a single egg which was taken 

 together with the female parent bird. The egg is white, short ovate 

 in form and measures 35 x 29.5 mm. 



RHINOPTYNX CLAMATOR (Vieillot). 

 Bubo clamator Vieillot, Ois. de 1'America Sept. p. 52. PI. 20. 1807. 



This species was noted at various points along the middle Ori- 



'While no specimens were obtained. I feel that a third additional species should be added. Several 

 times at Las Barrancas an owl was observed that I identified as Pulsalrix perspicillata.
