but at present my opinion coincides with that of other
naturalists, both as to the existence of species_, and of
those of Neara in particular.
This genus is the Cuspidaria of Nardo. It contains
many exotic species ; the late Mr. Hinds described and
enumerated seventeen in the ^ Proceedings of the Zoological Society^ for 18 i3, and Mr. A. Adams several more
in the ' Annals and INIagazine of Natural History ' for
March 1864. The name Necera was originally used for
a genus of Diptera ; but no one is likely to be misled
by the subsequent application of it to the Mollusca,
unless perchance in consulting an index to any work on
general zoology.
Otherwise the name given by Nardo
is more characteristic.

N. abhreviafo, Forbes in Zool. Soc. Proc. 1843, p. 75: F. & H. i. p. 201,
pi. yii, f. 7.
Shell triangularly oval, obliquely twisted to the posterior
side, nearly equivalve, extremely gibbous, fragile, semitransparent, slightly glossy and iridescent : sculpture, about a dozen
concentric plaits or folds, besides numerous fine but irregidar
intermediate stria? ; the surface is also marked by a few obscure
longitudinal hues, and the posterior side by a sharp rib which
runs outwards from behind the beak in a curved or flexuous
direction : colour greyish-white : epidermis yellowish-brown,
visible only at the edges and back : margins rounded on the
anterior side and in front, indented or flexuous ou the posterior
side, which is short, wedge-like, and considerably compressed
;
dorsal margins nearly equal in length, and straight : healcs
blunt, much inflected, somewhat inclined to the anterior side
umbones prominent ; the dorsal area is deeply excavated
cartilage small, yellowish-brown, occupying an elliptical cavity
in a parallel line with the liinge : Mnge-line obtusely angular:
hinge-plate narrow : teeth, a minute thorn-like cardinal in each
* Shortened.
