I adopt willingly the results of the accurate comparisons made by H. Strebel in 
uniting the above four so-called species, as I find no essential difference, neither in the 
specimens labelled with these names in different collections, nor in the above-quoted 
descriptions. | 
Amongst a number of examples collected by Herr Hége at Campeche I find the 
following measurements :— 
Long. 283, diam. 11, apert. 13 millim., 
5 » Il » 1d, 
” 23 99 104 9 123 99 
all apparently full-grown and similar in other respects. A younger shell with thin 
peristome measures :— 
Long. 20, diam. 10, apert. 11 millim. 
At Merida Herr Hoge obtained two full-grown specimens :— 
(2) Long. 29, diam. 10, apert. 134 millim. (Fig. 14.) 
(6) » 264 4, Ills » 14 3 (Fig. 15.) 
In this instance the extraordinary elongation of the first specimen is compensated by 
the narrowness of its last whorl. 
A Mexican example found by F. Deppe on Yucca filamentosa was referred by me, in 
Malak. Blatt. 1865, p. 11, with some doubt to this species; a re-examination of this, 
however, compels me to retract this determination, the said specimen being apparently 
nothing but a young individual of G. audebardi. The misunderstanding which might 
arise from Fischer and Crosse’s statement “in Republica Mexicana, Dr. Berendt” 2, is 
explained by his friend and companion Strebel (Mex. Beitr. Land- und Siissw.-Conch., 
ii. p. 45), who mentions that Dr. Berendt has collected also in Yucatan. 
In this species the apex is very obtuse ; the vertical riblets begin in the third whorl, 
and are here relatively stronger and more distant than in the following ones 
(fig. 14 a).
