ZOOLOGICAL LITERATURE, 
Entodonta lamelloaa (F^r.), young individuals found in the umbilicus of 
the old. Mdrch, Journ. Conch, xiii. p. 895, and xv. p. 267. 
[Entodonta ?] Helix lahyrinthica and lineata (Say), figured by Morse, Am. 
Naturalist, i. pp. 546, 646. 
Helix, The conchologist is still compelled to enumerate under this name 
numerous species, the jaw of which is either not known, or deviates but slightly 
from the type exemplified by Helix pomatia, and to divide them into a rather 
large number of groups founded on the general aspect of the shell, and on the 
habitat — the anatomical structure of the exotic groups being too little known at 
present. The Recorder’s researches show that the jaw is typical in H. siebol- 
diana, peliomphala, qucesitaj cicatrieosa, argillacea, unguiculastray and puhi^ 
cepuy which correspond to the groups AcustUy Camenay ChloritiSy and 'Alberday 
as also in Cochlostyla metaformisy whilst it is smooth, with crenated edge, in 
H. ptychostyla (group Plectotropis)y and smooth or nearly so in H brasilianay 
exceptiunculay zonalisy pyrostoma (groups Solaropsisy Planispway and Phania)y 
but faintly striated in H. zonariay and even faintly ribbed in H loxotropis 
(which form also part of Planispira). These, as well as Nanina amphidromay 
which is a true Nanina with reflected peristome, are rather unwelcome 
instances, proving that it is by no means safe to draw an inference from the 
form of the peristome as to the structure of the jaw. Martens, Preuss. Exped. 
ii. p. 173. 
a. Species from Europe, Northern Africa, and Western Asia : — 
[Group Gonostoma.] Helix constricta (Bonbde) found alive in the wood 
of Lourdes, Hautes Pyr^n4es, by D. Guestier j jaw described by J. B. G assies, 
Journ. Conch, xv. pp. 16-17. A somewhat different account of the jaw, and 
some anatomical details, given by St. Simon, ibid. p. 98. 
[Group Fruticicola.] Helix ptilotUy sp. n., Bourguig-nat, Tasl^, Catal. 
Moll. Morbihan, Brittany. — Helix brigantinayS^. n.,Mengo, Jornal do Sciencias 
Mathematicas phys. e nat. Lisboa, vol. ii. 1867, p. 170, Bragan 9 a, Portugal. 
Allied to H. inchoata (Morelet). An abstract of the description in Journ. 
Conch. XV. p. 344. — Helix villersiiy sp. n., Malzine, Faune Malacol. Belg. p. 
74, pi. 3. figs. 1-3, Abbey of Villers, is said to be near H. sericea and hispiduy 
but of a beautiful milky-white diaphanous colour [either an albino or dis- 
coloured, or belonging to quite another group than sericea j the figure is in- 
sufficient, the side view not being well drawn]. — Helix dussertianay sp. n., 
Bourguignat, Moll. Nouv. viii. p. 252, pi. 38. figs. 10-14, Algeria. 
. [Group Xehophila.] Helix paladilhiy sp. n., Bourguignat, Moll. Nouv. 
fasc. vi. (1866) p. 180, pi. 30. figs. 1-6, Montpellier. Allied to H. costidata 
(Ziegl.) [which is H. striatUy Miill.]. — H. rokniaca and satonnianay spp. nn., 
Bourguignat, 1. c, viii. 1867, pp. 260 and 254, pi. 38. figs. 6-9, and pi. 37. figs. 
16-16, Algeria. 
Helix variabilis. Gassies states that specimens of this species are found in 
South-western France, resembling in certain points H. ericetorum and H 
fasciolatay and that neither the elevation of the spire nor the relative size of 
the umbilicus are constant distinctive characters. lie is inclined to regard 
such specimens as the produce of the interbreeding of these species.
