PULMONATA. 
Bland & Binney, Ann. Lyc. N. York, x. pp. 158-170, review 
the systematic arrangement of the terrestrial Vulmonata, as 
represented in N. America, recapitulating the more recent re- 
searches into their dentition and jaw-structure. The jaw and 
marginal teeth are maintained, and the caudal pore abandoned, 
as primary characters for the distinction of subfamilies. The 
family Oleacinidce ( = TestacellidcB) is maintained, the Cylindrel- 
Ud(B are abandoned, and the Helicidce are divided into the fol- 
lowing subfamilies:— 
ViTRiNiNiE. Jaw simple, marginal teeth aculeiform : 3Iacrocyclis, ZoniteSj 
HyaUnUf Vitrina, Limax. 
llELiciNiR. Jaw simple, marginal teeth quadrate : ArtoUf AriolimaXy 
Binneia, Batulay Ilelix^ Ilolosjnra, Cylindrella^ Macroceramus^ Bulhnuhis, 
Cionella, Stenoyyra, Bupa, Vertigo. 
Orthalicinas. Jaw composite : Orthalicus, Ligum, Punctum. 
SucciNEiNJE. Jaw simple, with one upper accessory plate : Succinea. 
Prof. 0. Semper points out some mistakes in the anatomical descriptions 
given by Stoliezka (see Zool. Pec. viii. pp. 149 & 160), chiefly concerning 
what is called flagellum ” by the latter, and declares the peculiar bodies 
observed in Sesara infrendens to be spermatophores ; he defends bis own 
systematic disposition of the Zonitidee (see Zool. Pec. vii. p. 160), founded on 
anatomical differences chiefly in the generative organs. Mai. Blatt. xix. 
pp. 177-183.

A. Boring remarks that species of the same genus living sometimes with- 
out water, or in comparatively dry spots, have the aperture of the shell 
smaller than those which never leave the water or live in very moist 
localities. Inaugural Dissertation, Gottingen, 1872.
