type of a prior genus must be eliminated) and afomaria, a 
new name for lactea, Miill. Section 6 contained the Helix 
sulcata of Miiller, a form which Swainson, in 1840, made the 
type of his group Plicadomus. These eliminations leave 
H., lactea the valid nucleus of Schumacher’s group. .. . 
Beck’s use of Otala has no bearing upon the case, as he 
included none of Schumachev’s species in his group.” 
Against this von Méllendorff quotes from Herrmannsen 
and Beck, as he had not seen Schumacher’s work ; and after 
further remarks concludes to use the name Marmorana, 
Hartmann, for the group, placing “ Otala, Pilsbry,” as a 
synonym thereto. 
This conclusion cannot, however, be maintained, since 
Marmorana was based upon the species serpentina, which 
belongs not to the group under discussion, but to Lberus. 
Hartmann’s sole reference to Marmorana is the passage 
(apropos of a certain malformation) which reads: “ Herr 
Grat Porro hielt sie fir sehr merkwiirdig und sandte mir 
mehrere solche von unserer Huparyphia, auch von Marmorana 
serpentina; wirklich ist die Ursache dieser abnormen Fort- 
setzung schwierig zu ermitteln,” &c. Thus was Marmorana 
established. And von Mollendorff gravely concludes: 
“ Danach wurde Marmorana auf die Formenkreise von 
vermicu’ata und lactea zu beschriinken sein”’!

1. Leach’s Species of the Genus Geophilus. 
THE genus Geophilus, Leach, originally contained the fol- 
lowing species:—carpophagus, subterraneus, acuminatus, 
longicornis (Tr. Linn. Soe. xi. pp. 584-386, 1819). One of 
these must be the type of the genus. Longicornis was taken 
out by Newport (Proc. Zool. Soc. 1842, p. 180) as the type 
of Necrophleophagus. In 1845(Tr. Linn. Soe. xix. p. 429 &c.) 
Newport substituted <Arthronomalus for Necrophleophagus, 
and added the following species :—punctiventris, carpophagqus, 
similis (=carpophagus), Hopet, flavus, and opinatus. Since 
Newport expressly states that he changed Wecrophleophaqus 
for Arthronomalus, the two must be regarded as synonymous 
in the strictest possible sense of the term—that is to say, as 
having the same type species. It is superfluous, therefore, to 
pursue further the fate of the remaining species included 
under Arthronomalus with a view to ascertaining if one of
