Fie. testa elongate pyriformi, spira brevissima, mucronata ; ultimo anfractu postice 
inflato, antice prolongato atque sensim attenuato ; superficie costulis spiralibus atque 
transversalibus fenestrata, costulis ultimis tenuioribus atque in speciminibus adultis 
noununguam subobsoletis ; apertura perlonga, postice emarginata, antice late effusa ; 
labro ad suturam insinuato, antice paululum expanso, intus sulcato ; labio calloso, 
quinque-plicato, antice crassissimo, ad murginem exteriorem angulato, intus applanato. 
Spiral angle 110°. 
Height of last whorl : total height (considered as 1:00) ... 0:91 
As regard the peculiar form of this species and its relation to others, we have 
already, in the remarks on the genus, noticed all that was needed. The five oblique 
folds are very distinctly visible, and it is even not impossible that there may be 
more of them. They disappear on the margin of the aperture totally, which misled 
Forbes and D’Orbigny to describe the species under Pyrula. The anterior portion 
of the inner lip is very much angulated exteriorly and strongly thickened; the 
folds terminate over nearly its entire extent, as may be seen from the Fig. 10, Pl. VI. 
The transversal ribs are in young specimens of nearly equal strength with the 
spiral, forming on the place where they meet slight tuberculations and dividing the 
surface in regularly squarish lacunze. In more largely grown specimens the spiral 
ribs much predominate on the last whorl, occasionally alternating with secondary 
ribs. Besides these ribs there are strive of growth distinctly visible, being along 
the suture deeply insinuated and causing a similar emargination on the margin 
of the outer lip. There are four volutions visible on the figured specimen 
from Pondicherry, but the uppermost are devoid of the shell surface, for which 
reason it cannot be ascertained, whether the apex was mammillated or not, but if- it 
was, as seems probable, it could have been only slightly so, as compared with 
other roLurinZ. 
Localities.—Pondicherry and W. of Kullygoody in Trichinopoly ; at the former 
locality the species appears not to be rare; at the latter only a single fragmentary 
specimen has been as yet procured. 
Formations.—Valudayur- and Trichinopoly- groups. 
XVI. FULGURARIA, Schumacher, 1817. 
(Vide Adams’ Genera I, p. 165.) 
The principal characteristics of this genus lie in the elongated form, spiral 
striation, numerous plaits about the middle on the inner lip, much produced anterior 
extremity with the columellar lip sharpened exteriorly and more or less flattened 
enteriorly.
