OF SOUTITERN INDIA. 421 
Jere recto, antice subtiuncato, late effuso, intus breviler plicato; labio crasso, 
postice obsolete—, ante medium atque ad terminationem anteriorem valde-, plicato : 
plica antica obliqua, longitudinaliter subfurcata ; canali angustissimo, profundo. 
Spiral angle 100°; sutural angle 8-10°. 
Height of spire : total of shell (considered as 1:00) oon ee oor) O!Dde 
Width of shell : its height ( op > mo?) BAD AA ». 0°80. 
Shell strongly globose, spire somewhat produced and pointed, whorls convex, 
somewhat contracted at the suture, the last almost evenly rounded ; surface marked 
with numerous, fine spiral striz, two of which are always close to each other and 
separated from the next pair by a little broader sulcation than that between them- 
selves; the sulci are, as usual, transversally striated; aperture large, posteriorly 
pointed, anteriorly obtuse; outer lip moderately thickened externally, near the 
posterior termination somewhat angular, anteriorly obtuse and broadly effuse, inter- 
nally provided with short folds: inner lip thick, posteriorly slightly angular, in 
front of the middle portion and at the anterior termination strongly plicated, the 
~ anterior fold being oblique and furrowed longitudinally ; canal oblique, very narrow, 
but deep. 
Locality —N. W. of Veraghoor, in a coarse grained, soft, yellowish and whitish 
sandstone; not common. 
Formation.—Trichinopoly group. 
2. AVELLANA SCROBICULATA, Stoliczka, Pl. XXVI, Fig.9; Pl. XXVIII, Fig. 21. 
Avell. testa globulosa, transversaliter paulo expansa, spira brevissima, obtusius- 
cula seu apice acuminata; anfractibus convexiusculis, ad suturam paulo constrictis, 
ultimo paulo gibboso, superficie spiraliter anguste costulata: iterstitis excavatis, 
transversaliter striolatis sew punctatis; apertura postice angustissima, acuminata, 
antice rotundate terminanti, lata, marginibus crassis instructa; labro uniforme 
arcuato, intus denticulate plicato (vide figuram 9 b), labio ante medium et antice 
plicis crassis instructo ; canali angusto, non profunde inciso. 
Spiral angle 110°.

This species is distinguished by its short spire, rather globose and roundish 
form, the spiral strive or ribbings being all equally thick, and by the strongly 
thickened margins of the aperture, as compared with the size of the shell; the 
inner lip has a distinct posterior fold, but it is placed somewhat internally; the 
anterior denticulations of the outer lip are peculiarly strong. 
In general form and ornamentation this species resembles 4. Hugardiana, but 
differs from it in the disposition of the folds of the inner lip, if d’Orbigny’s figure 
(Pal. frane., terr. cret., II, pl. 168, fig. 17) be perfectly correct in this point. 
The species very seldom attains the usual size of Avell. ampla; most of our 
specimens (25) are not larger than the one of which a representation is given 
in Fig. 9 on Plate XXVI.
