LEPTINARIA. 317 
Hab. W. Guatemata: Retalhuleu, in woods, under decayed leaves, rare (Stoll). 
The most globose of all the species within our limits. A young shell (fig. 9 a), quite 
distinct by its form from ZL. elise, shows the parietal plate very clearly; but in the 
full-grown examples no trace of it is to be seen. 
Dr. O. Stoll describes the living animal as follows :—“ Animal pale grey ; anterior 
part of the body much more strongly developed than the shortened hinder part; upper 
feelers nearly cylindrical ; lower feelers forming only a short protuberance.” A sketch 
drawn by him from the living animal is reproduced on our Plate (fig. 9), but the 
outlines of the shell are drawn directly from one of his specimens.

Hab. Centrau Costa Rica: La Palma, at an elevation of 1500-1600 metres above the 
sea, beneath cactoids (Biolley, 1895 ; Pittier, 1897); San Francisco de Guadalupe,
