ZOOLOGICAL LITERATURE. 
Succinea (^Pellicula) convexa, sp. n., Martens, Mai. Bliitt. xv. p. 183, Porto 
Alegre, Southern Brazil. The jaw and lingual teeth are described and figured 
by Heynemann, ibid. p. 112, pi. 4. fig. 5, proving that Pellicula is not gene- 
rically distinct from Succinea. 
Athoracophorus hirudoy sp. n., Fischer, Journ. Conch, xvi. pp. 146 and 226, 
pi. 11, New Caledonia. Jaw as in Succinea y median teeth of the radula very 
small, the other tricuspidate. Mantle only indicated by a furrow, adhering 
to the common integument on all sides, a thick reniform internal shell. A 
caecum of the intestine near the orifice of the two hepatic ducts. This genus 
is identical with Janella (Gray, which name is preoccupied by Grateloup, 
1838, for a fossil shell), Aneitea (Gray), and Trihcniophorus (Humbert). Six 
species are known at present, from Australia, New Zealand, the New He- 
brides, and New Caledonia. 
Limnophila. 
Auriculidaj. 
Carychium exiyuum (Say), Northern, Middle, and Western States, Arkansas^ 
Texas, Tiyon, Am. Journ. Conch, iv. p. 6, pi. 1. fig. 3. 
Carychium Jilicosta, sp. n., Morelet, Moll. terr. et fluv. Voy. Welwitsch, 
p. 84, pi. 3. fig. 3, Angola. [It is very doubtful whether this is a true Cary- 
chiumJ\ 
Pedipea lirata (Binney), Lower California, Tryon, Am. Journ. Conch, iv. 
p. 10, pi. 1. fig. 88. 
Blauneria pellucida (Pfr.), Florida, also in a garden at Washington, 
Tryon, /. c. fig. 13. 
Pedipea unisulcata, sp. n.. Cooper, Proceed. Calif. Acad. Nat. Sci. vol. iii. 
part iv., California. 
Alexia myosotis (Drap.), from New England and New York, Tryon, 1. c. 
p. 6, pi. 1. figs. 1, 2. 
Leuconia aayi (Kiist.) unknown to American conchologists, Tryon, 1. c. 
p. 10, pi. 18. fig. 12, copied from Kiister’s figure. 
Melampua olivaceus (Carp.), Lower California ; hidentatus (Say), Atlantic 
coasts of the United States j Jlavus (Gmel.) and coffea (L.), Florida. Tryon, 
1. c. p. 7, pi. 1. figs. 4-8. 
Tralia pusilla (Gmel.), cingulata (Pfr.), and fioridana (Shuttl.), all from 
Florida and the adjacent keys, Tryon, 1. c. p. 9, pi. 18. figs. 9-11. This genus 
is distinguished from the preceding by the foot not being bifid posteriorly. 
[Pfeiffer has shown, Monogr. Auricul. p. 16, and Mai. Bliitt. vi. 1869, p. 117, 
that this character is of little importance, and leads easily to misapplication], 
Melampua atriutuay Pease, Am. Journ. Conch, iv. p. 100, pi. 12. fig. 14, 
Tahiti. 
Laimadonta [^Lcemodonta'] conica. Pease, /. c. p. 101, pi. 12. fig. 16, Pau- 
motu Islands. 
AuionoCy g. n. Closely allied to Melampua (Montf.) and Laimodonta 
(Nutt,), differing chiefly from the former in its thin and horny shell, and 
from the latter in its short spire and longer aperture.” A. riparia, sp. n., both 
margins of the aperture without plaits, except the one common to all Auri- 
culacea on the columella. Trinidad. Guppy, Transact. Scientif. Assoc. I'li- 
nidad, 1868, p. 244.
