68 CYLINDRELLIDiE. 



EPIROBIA, Strebel and Pfeffer. Distinct from Holospira by the 

 columella being perpendicularly costulated, but without spiral 

 plait. G. Berendti, Pfr. Mexico. 



EUOALODIUM, Crosse and Fischer, 1868. Shell subrimate, tur- 

 reted, cylindrelliform, widely truncate ; last whorl slightly free, 

 more or less cariuate ; 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. G. Ghies- 

 breghti, Pfr. (xcix, 55). 20 sp. Mexico. 



ANisospiRA, Strebel and Pfeffer. Shell somewhat like Eucalo- 

 dium, columella tubular with external plait. G. Liebmanni, Pfr. 

 (i, 1-2,13). 



CCELOCENTRUM, Crosse and Fischer, 1872. Pillar a hollow glossy 

 tube; sheir resembling Eucalodium, externally ribbed. Gylin- 

 drella hirris, 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 lamellae ; aperture semi- 

 circular, without plications ; no clausilium ; umbilicus deeply slit. 



General shape of shell like Clausilia, but without plaits or 

 clausilium 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 Eucalodium. G. 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- 

 ities of the lip united upon it by a callosity. 



Leia, Albers, 1850. 



Syn. — Lia, Morch, 1852. 



Distr. — 8 sp. Jamaica, Hayti. iv. il/awgrerz, Wood (xcix, 57). 



Shell ver}^ 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. 



PiNERiA, Poey, 1854. 

 Distf. — 4 sp. West Indies. P. Vieqiiensis, Pfr. (xcix, 58). 

 Shell imperforate, conically tun-eted, obliquely plicate; whorls
