THE NAUTILUS. 45 
PLANTERA, a banana plantation several miles up Rio Dulce 
from Livingston. For the first few miles the river is pictur- 
esque, passing between steep high hills covered with dense 
vegetation of varying shades of green. Sometimes the slope 
is broken by an abrupt face of rock. On one such face, larger 
than the rest, were many obscure figures and markings, in 
lines of lighter color, said to be drawings of an unknown race 
of people. The appearance was more like the marks from 
seepage water carrying lime. 
Pachychilus largillterti (Philippi). Only a few specimens 
found in a small river which was followed for some four miles. 
Ampullaria flagellata tristrami C. & F. In a small swamp 
near the Plantation buildings. 
Neritina lineata reticulata (C. & F.). With the above. 
Subulina octona (Chem.). A few in the yard under some 
loose stone. 
ESMERALDA. This plantation is on the left bank of Rio 
Dulce some three miles below the old Fort San Felipe, now 
in ruins. 
Guppya gundlachi (Pfr.). Fragments seen along the trail 
to Rio Saja. 
Opeas micra (Orb.). Under trash in front of a hut. 
Opeas pumilum (Pfr.). With the above. 
Cecilioides consobrina veracruzensis (C. & F.). Same as 
above. 
Succinea recisa (Morelet) or S. guatemalensis. With above. 
These are too young to decide to which species they belong 
with certainty. 
Helicina amoena Pfr. 
Amphicyclotus bisinwatus (Martens). Two bones. 
Ampullaria flagellata tristramt C. & F. On the border of 
the river among water plants and under drift lodgments. 
Pachychilus glaphyrus (Morelet). These are between 
immanis and the obeliscus of the lake. Numerous on the 
border of the river. 
Pachychilus pyramidalis (Morelet). Some fine large speci- 
mens were found in Rio Saja, under drift and other places 
protected from the force of the current.
