plait. C. Berendti, Pfr. Mexico. 
EUCALODIUM, Crosse and Fischer, 1868. Shell subrimate, tur- 
reted, cylindrelliform, widely truncate ; last whorl slightly free, 
more or less carinate; columella with a plica, not reaching the 
aperture. Jaw arched, finely striated, with a short laminar 
appendix, recalling that of Succinea ; teeth of the radula in trans- 
verse rows, tricuspidate, similar to those of Helix. C. Ghies- 
breghti, Pfr. (xcix, 55). 20 sp. Mexico.

C@ELOCENTRUM, Crosse and Fischer, 1872. Pillara hollow glossy 
tube; shell resembling Eucalodium, externally ribbed.  Cylin- 
drella turris, Pfr. (xcix, 56). 8 sp. L. California, Mexico, 
Guatemala. 
BERENDTIA, Crosse and Fischer, 1869. Shell turriculated, 
dextral, with obtuse summit and numerous whorls, the last one 
descending and detached in front; peristome continuous, widely 
reflected; columella simple, without lamelle; aperture semi- 
circular, without plications; no clausilium; umbilicus deeply slit. 
General shape of shell like Clausilia, but without plaits or 
elausilium in the interior; jaw very arcuate, with nine strong 
ribs; radula with a somewhat smaller tricuspid median tooth 
and thirty lateral and marginal teeth, the first tricuspid, the 
latter bicuspid. Except the jaw, there are many points of resem- 
blance between Berendtia and Hucalodium. C. Taylori, Pfr. 
(C. Newcombiana, Gabb.) Lower California. 
FASCINELLA, Stache, 1870. 
Distr.—F. eocenica, Stache.. L. Eocene; Albona. 
Shell smooth, thin, turriculated, small; axis perforated ; spire 
sharp; last whorl small, retracted ; columella plicate, the extrem-

Syn.— Lia, Morch, 1852. 
Distr.—8 sp. Jamaica, Hayti. L. Maugeri, Wood (xcix, 57). 
Shell very smooth, shining, subfusiform-cylindrical, apex 
truncate ; eight whorls, the last contracted below, carinated at 
the base; aperture oblong; columella plicate; peristome not 
continuous, reflected. The peculiar porcellanous surface of Leia 
will distinguish it at once from Cylindrella.
