 and being rather bigger. The other two have only a faint 

 trace of the lilac, and in both the base of the lower mandible

Very few individuals of this Parrot were observed ; in 

 flying it resembles au Amazuna, but looks smaller and darker,

The March specimen is apparently young, as it is much 

 richer in colour than the January bird. 



This Owl was fairly common in all the rougher grass- 

 lands, M'hcre it was flushed from the ground, and two that 

 I put up left the remains of a half-eaten " Tuco tuco " 

 {Ctenomys) behind them. It breeds in this district, tlie 

 nest being a mere flattened place under a tuft of grass, 

 I brought home three eggs, and there is a clutch of two 

 in Miss llunnacles' collection, taken on the 28th of January
