66 MOLLUSCA.: 
Much smaller and somewhat less elongated than the true G. turris. The impressed 
line immediately below the suture (fig. 4@) is not very distinct and not visible on the 
upper whorls; but there is an obtuse angulation of the surface immediately below the 
suture in all whorls except the 2—3 uppermost, which are quite smooth. ‘The colour 
is a rather dark brownish-fallow. 
The example from Guerrero here figured is somewhat larger than Strebel’s type 
specimen from Juquila. 
21. Glandina anomala. 
Glandina (Oleacina) anomala, Angas, P. Z. 8. 1879, p. 481, t. 40. fig. 9. 
Hab. 8.E. Costa Rica: hilly regions (Gabé 1). 
According to the author this is allied to G. turris, Pfr., and G. pseudoturris, Streb., 
which is confirmed by the figure. The suture is said to be strongly granulated, which 
is scarcely to be seen in the figure. 
Of course quite distinct from Oleacina anomala (Pfr.), H. & A. Adams, Gen. Moll. 
(Nothus anomalus, Albers, Die Helic. p. 169; Spiraxis anomalus, Pfr. Monogr. Helic. 
Vivent. vill. p. 258), which is a Jamaican shell. 
22. Glandina simplex. (Tab. IV. figg. 5, 5a, 6.) 
Glandina turris (Pfr.), v. Mart. in Malak. Blatt. vii. p. 11 (1865) *. 
Glandina simplex, Strebel, Beitr. Mex. Land- und Siissw.-Conch. ii. p. 35, t. 10. figg. 25, 25 a, b,c’. 
Oleacina (Glandina) simplex (Streb.), Pfr. Monogr. Helic. Vivent. viii. p. 823 *. 
Hab. 8.W. Mexico; Oaxaca (Uhde!*; mus. Berol. no. 4241). 
Well distinct from G. turris by its glossy surface, smaller size, and more slender 
form, and by the well arcuated columella. 
One specimen only known hitherto. 
G. candida, Shuttl. in Bern Mittheil. 1852, p. 202 (Diagn. no. 2, p. 22) (Achatina) 
[Pfr. Monogr. Helic. Vivent. iii. p. 512; Gray, Cat. Pulm. p. 25 (Oleacina); Fischer 
& Crosse, Miss. Scient. Mex., Mollusca, i. p. 130], from an examination of the typical 
specimen (fig. 6), now in the Museum of Berne, seems to be a somewhat smaller, 
thoroughly bleached example of the same species. Although the name is of anterior 
date, I prefer not to use it, because it is founded on an accidental deterioration of the 
specimen. 
23. Glandina conularis. (Tab. IV. fig. 8.) 
Achatina (Glandina) conularis, Pfr. P. Z. 8. 1855, p. 100°.
