PSEUDOSUBULINA. 303 
Var. gracilior, n. 
Pseudosubulina berendti, form B, Strebel, loc. cit. p. 119, t. 7. fig. 7 a’. 
Whorls 103-11, the last, if seen from the dorsal side, a little more than one-fourth of the whole length 
of the shell, which varies from 94 to 114 millim.; diameter 24-24; aperture 2-2j in length, and 1-13 
in breadth. 
Hab. ¥%. Mexico: Vera Cruz and Mirador (Strebel ®); Cordova (Hoge). 
2. Pseudosubulina (?) chiapensis.

Pseudosubulina chiapensis, Strebel, Beitr. Mex. Land- und Siissw.-Conch. v. p. 119, t. 7. fig. 17 , 
Hab. S.E. Muxico: Chiapas (Ghiesdreght 1~* °). 
GUATEMALA (Sarg *). 
It is not quite certain that the Guatemalan shell described and figured by Fischer 
and Crosse belongs to Pfeiffer’s species, which has been redescribed by Strebel from 
Chiapas specimens; but as I have no examples from either locality for examination, I 
can offer no opinion concerning them. 
3. Pseudosubulina (?) sargi. 
Subulina sargi, Crosse & Fisch. Journ. de Conch. xxv. p. 272 (1877)'; Fisch. & Crosse, Miss. Scient. 
Mex., Mollusca, i. p. 637, t. 26. figg. 8, 3a, 5°. 
Hab. S.K. Mexico: Teapa in Tabasco (H. H. Smith). 
N. Guatemata: Coban (Sarg? 2). 
The glossy surface with fine crowded costzx (“‘ stries pliciformes et serrées””) seems to 
place this species in the genus Pseudosubulina, although the columellar margin is said 
to be arcuated and provided with a notch, which does not reach the basal end. 
4. Pseudosubulina (?) trypanodes. (Tab. XVII. figg. 16, 16a, 0.) 
Achatina trypanodes, Pfr. P. Z. 8. 1856, p. 879 1; Malak. Blatt. iii. p. 234 (1856) *; Monogr. Helic. 
Vivent. iv. p. 616°. 
Subulina trypanodes, Fisch. & Crosse, Miss. Scient. Mex., Mollusca, i. p. 636°. 
Hab. 8.E. Mexico: Chiapas (Ghiesbreght 4). 
Nowhere figured. According to the description, it somewhat resembles P. fortis in 
size and colour, but is at once distinguished by the number of whorls being twelve at 
the length of 13 millim. 
I am indebted to Mr. Edgar Smith for a drawing of the type of this species, and 
from this our figures are taken. ‘The form of the aperture confirms me in the supposi- 
tion that the species may belong to the genus Pseudosubulina, but this cannot be 
definitely decided till the structure of the radula is known.
