- CENTRAL GUATEMALA: on the limestone mountain ‘* La Pedrera,” north of the city of 
Guatemala, on the ground under Mimosa-shrubs, and on the branches cf trees 
covered with Bromeliaceew, during the dry season locked up by a thin mem- 
branous epiphragma (Stoll). 
CentraL Costa Rica: La Urraca, near San José (Biolley: var. without band). 
The specimens I have seen from Teapa, San Gerénimo, La Pedrera, and Las Mercedes 
are not all full-grown, with straight thin peristome, but they are easily distinguishable 
from H. cordovana of the same age and size by the inflated form of the shell; also the 
colour is more reddish-brown or yellowish ; the band is similar. The spire is either 
quite flat, with somewhat deepened centre, as described by Pfeiffer1, or more or less 
convex, as figured by Fischer and Crosse 8; but there are no other differences between 
the typical form and the variety. 
Our figure i is taken from the Purula specimen. Tristram’s species —” is founded on 
a not full-grown specimen.
