as many plate-like compartments, and the marginal teeth not 
lateral, more slender than the lateral teeth. Bland & Binney, 
Ann. Lyc. N. York, x. pp. 252-255, pL 11. figs. 1-7. 
\_rellicula] Succinea appendiciilata (Pfr.). Jaw, exhibiting the type of the 
Goniognatha, described and figured, iid. ibid. p. 20G, pi. 9. fig. 2. 
Amphibulima patula (Brug.). Animal sometimes completely 
retracted into shell ; jaw slightly arcuate, divided longitudinally 
by about '45 delicate ribs into as many plate-like sections of 
the same character as those of Cylindrella and many species of 
Bulimulus ; marginal teeth bicuspid. lid, ibid. pp. 223-225, 
pi. 11. fig. 8. 
Sini 2 mlopsis mastersi, sp. n., Brazier, P. Z. S. 1872, p. 619, Ld. Howe’s I. 
[PunctUTri] Helix pygriKsa (Drap.). Jaw composed of 19 plates 
and horseshoe-shaped ; radula exhibits the type of Helix, con- 
sisting of 39 longitudinal and 1 14 transverse rows of bicuspid 
teeth ; the lateral teeth, except the outermost, do not difi'er from 
the median. This species is therefore to be placed among the 
Goniognatha, and probably in Punctuin (Morse) . G. Schako, 
Mai. Blatt. xx. pp. 178-180, woodcuts. 
[Bulimulus.'] The jaw and radula of Bulimus guadelupensis 
(Brug.) has been examined by P. Fischer : the jaw is simple, 
with 14—16 scarcely oblique ribs, the innermost narrowest ; tlie 
teeth exhibit the type of Helix, the median having a middle 
large, and on each side a small lateral point; the lateral teeth 
arc tricuspid, the marginals short and bicuspid, the inner point 
being the longer. J. de Conch, xx. p. 293. [As tliis species 
is, historically, the type of Bulimulus (Leach), that generic 
name must be restricted to the species of which the radula is 
not very different from that above described, and the species 
agreeing in the radula with Orthalicus must be removed 
from it.] 
[Bidimulus] Bulimus nulacostylus (F(5r,) and aurissileni (Born) : marginal 
t(',oth similar to lateral ; jaw mcmbranacooiia, in one piece, but divided by 
delicate ribs into more than 60 plate-like sections, as in Bulimulus, Cylin- 
drella, &c. Bland & Binney, Ann. Lyc. N. York, x. p. 222. 
[Bidimtdus] Otosiomus loxanus, sp. n., Higgins, P. Z. S. 1872, p. 686, pi. 66.

Bulinmlus gabbi, sp. n., Crosse & Fischer, J. de Conch, xx. p. 223, Mexican 
California: allied to palUdior (Sow.). 
Orthalicus (Porphyrobajiha') bucldeyi, sp. n., Higgins, 1. c. p. 685, San 
Lucas, Ecuador. 
Cylindrella maugeri (Wood). Variable in colour, which fades even when 
not exposed to light. The animal always lives on plants, unlike the other 
CylindrellcB. Gloyne, J. de Conch, xx. pp. 33 & 34.
