The country around Cerdas is not flat,Tout tolling and 
somewhat rough in places,hut with long wide valleys. 
The higher portions have very little puna grass and 
Tola,hut much low,tough thorny plants,while in the 
valleys there is much Tola. We covered a large area of 
country in search of the Rheas,towards the northeast, 
hut few were seen,about five in all,of which one adult- 
male and one young one were secured. Phrygilus fruticet| 
was common in places here,also quite anumber of 
TJpucerthia dumetoria hypoleuca were seen and three 
secured,and 2 U. andaecola ,and 1 Speotyto cunicularia .

But two days were spent in Oploca in Pebruary(24-25) 
1938,due chiefly to the fact that it was Carnival 
time and there were no servant^ in the house,so we 
were forced to go over to the other hacienda,Salo. 
Very little was seen or collected during these two 
days that had not,been taken in 1936(late June and 
early July). The additions were Micropus _ ' sp. 
Pygochelddon cyanolpuca patagonica; Patagona gigas; 
Leshia sparganura;Pseudocolopterys acutipennis; 
Spizitornis parulus aequatorialis. 
The following taken in 1936,were not seen either at 
Oploca or Pinca Salo: Leptasthenura fuliginiceps; 
Hirundinea bellicosa pallidiorjMuscisaxicola capistrata] 
Muscisaxicola maculirostris.

Pive strenuous days were spent at the other hacienda, 
Pinca Salo,with rather surprising results. On the 
previous visit there in 1936,little time was spent in 
the field and most of the collecting was done in the 
valley. This y ear saddle mules were available for 
Delgado and myself and we made several trips into the 
mountains on both sides of the valley,working up to 
at least 13,000 feet. In the higher altitudes were 
taken the following,not secured in ,1936: 
Asthenes sp.(17577); Asthenes modesta hilereti(?); 
Cnemarchus rufipennis;Muscisaxicola alpina grisea; 
Xolmis murina;Ochthoeca l.leucophrys;Phrygilus unicolor 
tucumanus; Oreomanes fraseri; "Big Billed"Spinus(?) 
(17619). In the valley,at the little marsh was taken 
a new Swallow(l7647),also Sicalis auriventris (common; 
Patagona gigas was abundant also up in the hills to ea; 
east,and Oreotrochilus adela. 
I feel that this region was not figly exhausted,and 
that further work there might yieW- species.
