THE NAUTILUS. 49 



Helicina amoena Pfr. 



Helicina tennis var. lindoni Pfr. 



Helicina fiavida Mke. or H. trossula Morelet. 



Helicina coccinostoma Morelet. 



Luddella lirata (Pfr. ). 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 trisframi 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 mdiorum (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.
