THE NAUTILUS. 49 
Helicina amoena Ptr. 
Helicina tenuis var. lindoni Pfr. 
Helicina flavida Mke. or H. trossula Morelet. 
Helicina coccinostoma Morelet. 
Lucidella lirata (Pir.). Lake drift. 
Panzos, State of Alta Verapaz. The head of navigation on 
the Polochic River. No land species found here, although a 
half day was spent on a stroll up the R. R. to a good-sized 
creek which was followed for some distance and the return made 
over the mountain, with no results whatever. 
Ampullaria flagellata tristrami C. & F. Two good large speci- 
mens, dead, found in a marshy place near the R. R. 
Pachychilus pyramidalis (Morelet). Young specimens plenti- 
ful in a creek near the town. 
Pachychilus mdiorum (Morelet). A few specimens taken with 
the above. 
Amnicola panzosensis Walker. From a pool formed by a small 
stream from a spring or seepage on the mountain side. 
Pisidium singleyi Sterki. With the above Amnicola. 
CHEJEL, State of Alta Verapaz. At the end of the R. R. the 
writer was met by a guide and horses sent by Mr. Robert Hemp- 
stead, and was conducted to his residence on the Chejel coffee 
plantation. A nice home on the side of the mountain, some 
2000 ft. elevation, with roses, violets and other flowers in the 
front yard. From the veranda on the other side of the house 
the mountain side is a steep slope to the base where it meets the 
base of the next mountain. An extensive mountain view in all 
directions is seen from this veranda. 
Pachychilus wndiorum (Morelet). Mr. Hempstead kindly 
showed me the spring from which we picked up a few speci- 
mens of this species. These are lighter-colored and do not show 
the mottled color of those from the Cavech. This was the only 
species found at Chejel. 
Pachychilus corvinus (Morelet). Immature specimens I took 
for this species from a rill that crosses the road on the way to 
Purulha.
