Pfeiffer 12-14 did not know the habitat of the form insignis. A nearly allied, but 
more ventricose form, 67, 29, 31 millim., the locality of which is unknown, is repre- 
sented by Chemnitz (Buccinum striatum, part.), Conch. Cab. ix. t. 120, figg. 1028, 1029 
(copied in ed. 2, Achatina, t. 8. figg. 38, 4, under the name of A. liebmanni); it 
approaches the above-quoted figure of Reeve 11. 
G. cognata, Strebel, Beitr. Mex. Land- und Siissw.-Conch. ii. p. 12, t. 4. fig. 7 (Pfr. 
Monogr. Helic. Vivent. vill. p. 332), from Tehuantepec, seems to be intermediate 
between G. liebmanni and G. audebardi, having the more broad and solid shell of the 
former, but the weak sculpture of the latter. G. radula, Strebel, loc. cit. p. 13, t. 3. 
fig. 8 (Pfr. Monogr. Helic. Vivent. viii. p. 333), also from Tehuantepec, may be a 
dwarf form of G. lebmanni. 
Achatina marminii, Deshayes, in Guérin’s Mag. Zool. 1831, t. 19 (copied in Martini 
& Chemnitz, ed. 2, Achatina, t. 3. fig. 2; Pfr. Monogr. Helic. Vivent. ii. p. 288), 
locality unknown, is possibly a not full-grown specimen of G. liebmanni. 
G. nympha, Fischer & Crosse, Miss. Scient. Mex., Mollusca, i. p. 115, t. 6. fig. 9 
““ Mexico (Sallé),” without nearer indication of locality, is founded on a large bleached 
specimen (long. 60, diam. 233, apert. 29 millim.) which bears a considerable resemblance 
to G. liebmanni, only its columella seems to be more arcuate.
