3. LyriA GRANULOSA, Stoliczha. Pl. IX, Figs. 10 and 11. 
L. testa elongata ; anfractibus subconvexis, gradatis, transversaliter acute-, spi- 
raliter late-, costatis: costis transversalibus circiter 15 in uno cireuitu, usque ad 
suturam extensis, spiralibus in anfractibus superioribus quinis sew senis, in ultimo 
numerosis, omninis latis, in costis transversalibus subtuberculatis, interstitiis profundis, 
fere equalibus separatis ; canali sinistrorse lateraliter curvato ; labio multiplicato : 
plicis anterioribus fortioribus, minoribus nonnunquam alternantibus. 
Spiral angle 37°; sutural angle 10°. 
The great number of sharp and nearly straight transverse ribs, which extend 
over the total width of each whorl, show a resemblance in this species to Volutilithes 
radula, from which it is readily distinguished by its more elongated form, the 
last whorl being nearly of equal height with the spire, while the same greatly 
exceeds the elevation of the spire in the other species. The spiral ribbings of Lyr. 
granulosa are remarkably broad, not very high, forming moderate tubercles, when 
crossing the transverse ribs; they vary from 5 to 6 on the upper volutions, and the 
two posterior or upper ones are placed closer to each other than the rest; an equally 
marked distinction from V. radula, Sow. Towards the anterior extremity the 
strength of the ribs decreases, and they are here often replaced by alternating rows 
of smaller and larger tubercles. 
Although several specimens have been procured from the whitish sandstones near 
Koloture, none of them has the aperture perfectly preserved. The length of the canal 
may be calculated from the fragment on Pl. IX, Fig. 11; it was a little bent to 
the left side. The inner lip exposes a great number of plaits in its entire length, the 
anterior ones are strongest, and often alternate on the margin of the aperture with 
other short plaits; the posterior die out gradually, and, in consequence of the inner 
lip being thin, the spiral granulated rows of the shell-surface become apparent ; this 
is also clearly visible in the figured fragment (Fig. 11), the columellar margin of 
which has been exposed for that purpose. According to a small specimen, which 
shows an original portion of the outer lip, this had a sharp margin, grooved internally 
as indicated by, though not dependent upon, the spiral ornamentation on the exterior 
surface. 
Localities.—In whitish sandstone near Koloture, and in a similar sandy-limestone 
between Andoor and Veraghoor, in the Trichinopoly district. 
Formation.—(?) Trichinopoly group, both the mentioned localities are, however, 
close to the uncertain boundary of the Arrialoor group, and the mineralogical 
character of the rock is the same as that of the typical Arrialoor sandstone from the 
neighbourhood of Arrialoor, so the species may rather be looked for in the Arrialoor 
beds, should these remain separated from the Trichinopoly group.
