broader than the rest; whorls slightly convex, the last being by far the largest. 
The aperture is oval, posteriorly obtusely pointed and canaliculated, anteriorly sub- 
truncate; the outer lip is externally very broadly thickened and striated, internally 
it appears to be nearly smooth; the inner lip is very thick, especially about the 
middle, and has in front an unequally crenated edge, anteriorly it is thinner, insi- 
nuated, and provided with two folds, the first of which forms its anterior termination. 
This interesting species was at first described by Forbes as a Tornatella with 
thick lips; a fragment of the same was figured by d’Orbigny as Acteon uniden- 
tatus, while the same author placed Forbes’ species subsequently in the genus 
Avellana. Meek, as already mentioned, proposed for it the name <Aptycha. 
Having lately examined Forbes’ original specimen in the London Geol. Society’s 
collection, I soon found after exposing the rock, covering the aperture of that 
original, that it belongs to Ringicula, forming by its large size and greatly 
thickened inner lip a transition to Luptycha of Meek. The unequal crenulation 
in front of the lip is very peculiar, though not quite unknown in recent and fossil 
species of the same genus. 
Locality —N. of Karapaudy, in whitish, soft sandstone; apparently very 
rare; we only possess two imperfect specimens, and I suspect the one described by 
Prof. Forbes was from the same or nearly the same locality, for the rock in which 
it is imbedded is pretty nearly the same as that of our specimens. 
-Formation.—Arrialoor group.

This species is distinguished by its very regular, ovately globose form, having 
the surface marked with spiral, punctated impressed lines, which are separated by 
broad and flat ridges, being obsoletely transversally striated; about the middle and 
on the anterior portion of the last whorl these ridges are somewhat narrower than 
posteriorly. The aperture is posteriorly very narrow and sub-canaliculated, anteriorly 
roundish, the outer lip being anteriorly broadly insinuated; the inner lip forms a 
long, horizontally (or parallel to the axis of the shell) projecting rather thin plate, 
anteriorly it is deeply insinuated and terminates with a thick, roundish fold, in 
front of which there is a very narrow channel separating it from the outer lip.
