Penelope s. sclateri .while ; in the valley of Sania pata 
we took P. obscur a "bridges !. -i had never before seen 
Piplle above 2,000 feet (Rio Coroco) __ 
Many species of Thrushes were present; Turdus 
rufiventris(lower down),T.albicollis,T. 
Catharus dry as .and the rare Platy.cichle flavines

was found and \B& lara^cireTPafnew TabeTJ~ Thamnonhilus

on the Meson I found Melanopareia maximiliani. 
Trogomirus rersonatus and PharomacrUS a'ntisiehsis 
and the rare Ta.nger , Tangara argyr.oph en ges , were not rare. 
Crypturellus obsoletus and tataupa were abundant in the 
forest, also Tinamus.'t'su was seen but not secured; 
Rhynch o ±1 i s ru f esoen s ma culled! i s waa. ta ke n dri _the high 
grass lands and a small JTothoprocta or Fothura was seen 
several times but, not secured. 
The re seemed to be no. end.-to. -the sped as—to- he found - 
in this wonderful forest,and I much doubt whether we 
secured ali the species there,or even saw them. 
The reason.for the abrupt change in - flora and f R un 
here is perfectly obvious. The mountain range ruhnin 
rnore or less north, and south or southeast! through' ' 
Samaipata. f ones more oh less the watershed-between 
the Fizque basin and the streams running east toward 
Gputa CruhancT the Rib Surutu and' others. Prom here to 
the eastward—the-mountains,’while still persisting for 
a considerable distance,are much lower and do not ser¬ 
iously obstruct the rain hearing clouds from the north 
ast, ich are large stopped by-the high range runn - it 
through Samaipata. The clouds-sweep into this valley 
from east and d e their-water here,but usually 
..do., not. .pass_ ..aver further, to. the west, except in the. s e as or 
of heavy rains(December to April). The flora seems to be 
unite different to a large degree. There is more r, 
yjj f.h 1 1 t.t.T, e , apringa and tinjr_rivulets high up on the- .- 
slopes,while in all the other valleys water is almost 
no existent.except for tiny trickles lb the bottoms of 
the. valleys. _ — . , 
I was very anxious to work in one of the valleys about 
"C to T5 wiles to the .eastward,at an altitude of 
a-mroximately 2500 feet,but la.ck of . tim e did not oer^, 
while the matter of transportation was very difficul^JP 
This was not so import,since we have all of Steinbach' 
collections and data-on this region,and i t was imperative 
t'q get out and over to Sues before the heavy rains 
set in.
