HYALINIA. 117 
Binney, A. Gould, and Pfeiffer; but the specimen agrees very well with those from 
North America in the Berlin Museum and in Albers’s collection. 
6. Hyalinia subhyalina. 
Helix subhyalina, Pfr. in Malak. Blitt. xiv. p. 196 (1867) *; Monogr. Helic. Vivent. v. p. 476°. 
Zonites (Hyalinia) subhyalinus (Pfr.), Fischer & Crosse, Miss. Scient. Mex., Mollusca, i. p. 172°; 
Pilsbry, Proc. Acad. Phil. 1891, p. 812+. 
Hab. Ki. Mexico: Vera Cruz (Berendt 1-8); Orizaba, on hills (Heilprin *), 
Strebel suggests that this may be the young state of the preceding. 
7. Hyalinia permodesta. | 
Hyalinia permodesta, Strebel, Beitr. Mex. Land- und Siissw.-Conch. iv. p. 19, t. 4. fig. 97. 18¢0 
Hab. E. Muxico: Plantation Mirador, near Jalapa (Strebel 1).

8. Hyalinia indentata. 
Helix indentata, Say, in Journ. Acad. Phil. ii. p. 372 (1822)*; Binney, in Bost. Journ. Nat. Hist. 
iil. p. 415, t. 22. fig. 3°; A. Gould, Invert. of Massach. p. 181, fig. 109°; Pfr. Monogr. 
Helic. Vivent. i. p. 59*, and in Martini & Chemnitz, Syst. Conch.-Cab. ed. 2, Helix, i. 
p. 221. no. 190, t. 34, figg. 12-15°; Binney, Terr. air-breath. Moll. N. Am. ii. p. 242, t. 29. 
fig. 2, & iv. p. 119°. 
Hyalina indentata (Say), Binney & Bland, Land & Fresh-water Shells of N. Am. p. 35, fig. 44 
(also figg. 46, 47, jaw and radula) *. 
Zonites indentatus (Say), Binney, Manual of Am. Land-Shells (in Bull. U. 8S. Nat. Mus. no. 28), 
p- 62°; Suppl. i. p. 139, t. 4. figg. H, 1’. 
Zonites (Hyalinia) indentatus, Pilsbry, in Proc. Acad. Phil. 1891, p. 312”. 
Hab. Norta America: from Canada to Texas, and from Dacotah to Florida? 8, 
S.W. Mexico: Yautepec, Morelos, Southward from the city of Mexico and also the 
plateau on the upper confluents of the Rio de las Balsas (Hezlprin 1°). 
Probably also in Northern Mexico. The Latin name “indentata” is to be under- 
stood in the signification of the English “indented.” According to Pilsbry 1, this is 
the most abundant of the smaller Zonites in Texas.
