in its favor: thoug d truth, it really proves nothing with

- The proposed genus Anomalodonta of Miller identical with 
the earlier Megaptera of Meek.—In the first issue of the Cincin- 
ati Journal of Science I observe that the editor, Mr, 8, A. Miller, 
proposes a new genus under the name of Anomalodonta, to include 
a group of shells allied to Ambonychia of Hall. These shells con- 
stitute a very interesting type, evidently belonging to the family 
Aviculide. Like Ambonychia, they are destitute of an anterior 
wing, but have, posteriorly, a very large one, which gives the shell 
i jiller’s type specimens show them to 
have a broad striated area, such as Myalina possesses, with, at 
Myalina, as for example in M. ampla of Meek: and Hayden, so 
that, although enerically distinct from Mr. Miller’s shell, there 
seems to be littl i 
ating costz, unless he is right in stating that his shell has a large 
impression of the anterior adductor muscle, which, in view of the 
with Ambonychia, the hinge of his shell differs materially in want- 
ing the two anterior well-defined teeth of that genus, and also its 
three elongated posterio-lateral teeth. 
his genus Anomalodonta was roposed for a group of shells 
identical with the one for whic Meck & Worthen proposed the 
subgeneric name of Megaptera in the Proceedings of the Chicago 
Academy of Science in 1866. Mr. Miller himself states that his  ebdd 
posed genus will include chia legaptera 
(Ohio B aleontology, vol, i, p. 131), of which he says Mr. U. P. James
