THE NAUTILUS. 45 



PLANTERA, a banana plantation several miles up Eio Diilce 

 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 raoe 

 of people. The appearance was more like the marks from 

 seepage water carrying lime. 



Pachychilus largillierti (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 micro, (Orb.). Under trash in front of a hut. 



Opeas pumilum (Pfr.). With the above. 



Cacilioides consobrina veracruzensis (C. & F.). Same as 

 above. 



Succinea recisa (Morelet) or 8. guatemalensis. With above. 

 These are too young to decide to which species they belong 

 with certainty. 



Helicina amoena Pfr. 



Amphicyclotus bisinuatus (Martens). Two bones. 



Ampullaria flagellata tristrami 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.
