Hab. E. Mexico: San Andres Tuxtla, near Vera Cruz (Sallé °°). 
Dr. O. Stoll found specimens of this species on loamy declivities, between blades of 
grass, before sunrise; later in the day it conceals itself beneath decaying leaves. For 
the variety nubeculatus, Pfeiffer 1°18 cites “‘ Central America,” upon the authority of 
Morelet, from a specimen in Cuming’s collection. Fischer and Crosse 2° do not appear 
to have seen corresponding specimens from Morelet; but they have given the name 
nubeculatus to a smaller, unicolorous shell, collected at San Andres Tuxtla by Sallé. 
The living animal is described by Dr. O. Stoll as follows :—* Body rather narrow, 
24 centim. long; the back in the middle part longitudinally wrinkled, before and at 
the sides longitudinally and transversely wrinkled; pale greyish-brown, with two 
blackish lines, one behind each of the upper feelers. These latter 6 millim. long, 
blackish, on the inner side pale brown. Lower feelers 1 millim. long, conical, 
blackish, but paler than the upper ones. Hinder part of the foot flat, pointed, without 
median crest.”
