Hab. E. Mexico: Vera Cruz, on bushes and shrubs—probably stunted by the aridity 
of the soil (Strebel 21). 
The prevailing pattern of all the forms is a large pale reddish-brown band on the 
upper half of the last whorl; a row of small dark spots at the lower limit of this band 
is often seen on the upper whorls, and in some specimens also on the last, the band 
itself vanishing in proportion as these spots are conspicuous. Specimens without any 
band, of a uniform whitish or pale reddish colour, are found chiefly in the variety a. 
The original specimen of Pfeiffer’s H. berendti exhibits no trace of irregularity and 
deformity, and it is therefore to be regarded as a distinct variety, characterized by the 
concavity and angularity of the last two whorls. Its exact locality is not known: 
probably it was established on a bleached specimen found on the sea-shore at Vera 
Cruz. 
H. sandozi, Shuttl. (in Bern. Mittheil. 1852, p. 303, Diagn. no. 3, p. 43, and Pfr. 
Monogr. Pneum. Vivent. ii. p. 197), is a deformity of this species. Owing to the kind- 
ness of Prof. Th. Studer, I have been enabled to examine the original example in the 
late Mr. Shuttleworth’s collection; it proves to have been broken during life just 
behind the aperture, and to have restored itself, the newly formed peristome not 
meeting exactly the remains of the old near the columella, the slight inflection
