hills on east side. The valley runs nearly north and 
south,a little to east. There is no running water in 
valley and whole region is very dry. The formation 
•throughout whole region is red sandstone ;:and red sal 
sandyloam or sand and clay. The high range to west o^ 
town forms a series of high cliff along its face and 
there are no streams running out of it,except a few 
small springs, on* of which furnishes v/ater to the village 
being piped to the plaza.About a mile below town there i 
a deep,panyon-like valley running far back into the 
western range,enclosed on upper portion by high sandston 
cliffs. At upper end of this valley a small creek is pr€| 
present which soon dissapears into the sand of the 
floor of valley. There are numerous short,wide valleys 
or pockets in the hills on both sides of the valley, 
whose outer ends have,been raised by silt flowing down 
the big valley,so that when it rains there are formed 
shallow ponds. Two days after our arrival here there 
fell a heavy downpour which filled some of these ponds 
but not all, It v?as at one of these that the pair of 
Ducks and the Herons were taken,and at which was a flock 
of about 25 Jacanas. ^THere is permanently water at the 
upp^r end of this pond and a patch of cat-tails,but it 
was difficultto tell how much water v/as there before it 
rained. Ifuch of the valley floor ha.s been cleared an^^ 
planted to corn etc(Corn just being planted now) 
However large areas are wrood^d with acacias and other 
trees,with mjuch low, tangled thory scrub. Along the sides 
of the valleythere are more lare acacias and miost of the 
had new green leaves,also many out on plain,but up in 
the hills on both sides the trees ai*e still mostly bare, 
but the buds are.swelling .rapidly on lower slopes after 
the recent rains. There had been one or two heavy rains 
babout a week before we arrived. Birds were found to 
be abundant,a. fewr species very common (see notes and lis 
and many species were taken or observed. In five days 
collecting 110 specimens v/er taken,representing 66 speci 
while 43 other species were observed and identified with 
without question. However but 10 species were added to 
the years list,.of w'hich 7 were n'w to the Bolivian 
collection. Fany species taken or seen at Villa. Montes 
were absent here. But 8 of the species new' for Villa 
Montes were taken here,while 11 of those new at Entre 
Rios were taken.7 new at Fortin Gampero taken,but 2 of 
.those from Vermiejofnew there) and 15 species new at 
Rio lipeo wrere taken. Perhaps more time spent here 
and po)Llecting further afield wrould h&VB given 
additional sp,ecies,but the time was too limited.
