OF SOUTHERN INDIA. 21 
Pug. manubriatus, Gabb (Palzeontology of California, Vol. I, p. 125) is probably 
more allied to this species than it appears to be from Mr. Gabb’s figure (loc. cit. Pl. 29, 
Fig. 229), and I would not in the least be surprised, if both were found to be identical. 
In Fig. 229 the traceable suture shews, that the callosity was not present in its entire 
thickness, and the want of the same near the anterior extremity seems to prove, that 
this has been partly injured. We possess several specimens with such diminished 
thickness of the inner callosity, and with the incurved termination of the anterior 
canal broken away ; in this state our specimens do not exhibit any very remarkable 
distinctions from Gabb’s figure. 
Localities. N. of Alundanapooram (very common), Kolakonuttom, Serdamun- 
galum, Anapaudy, Monglepaudy, Seraganoor, E. of [lpagoody in Trichinopoly district. 
Formation. 'Trichinopoly group, of which the described species seems to be a 
very characteristic fossil. 
2. PUGNELLUS GRANULIFERUS, Stoliczka. Pl. III, Figs. 6—8. 
Pug. testa ovata, crassa, spira brevi, angulo circiter 75°; anfractibus quinis vel 
senis, convexis, transversaliter granulato-costatis, wna serie granorwm crassiorum prope 
marginem suturalem sejuncta, spira vie quintam partem totius altitudinis occupante ; 
anfractu ultimo posterius transversaliter oblique costulato, ad medium spiraliter 
granulato, antice sublevigato et multo angustiore; apertura ovali, elongata, antice 
angustata, interne levigata, callosissina, marginibus callositate conjunctis ; labro pos- 
terius prope medium uncinato: unco crasso, contorto, posticé extenso, lateraliter 
compresso, infra plus ninusve acuto, interne atque externe canaliculato ; labro antico 
profunde insinuato; rostro prolongato, crasso, lente exterius contorto, terminatione 
incurvo, intus canaliculato, extus medio impresso seu furcato: impressione scepius 
callositate fere obsoleta ; labio callosissimo, accumulato, spiram fere totam tegente. 
As regards the form of the shell, this species agrees in every way with that of 
Pug. contortus, to the description of which we refer in its greater details. The 
differences consist in size and ornamentation. 
All the specimens of Pug. granuliferus are even in the first stage of age thicker 
and more ventricose, and they grow to a much greater size, the usual height in the 
direction of the spiral axis beng 40 mm., and the width including the hook-like 
lobe somewhat more than 80mm. The aperture is anteriorly a little narrower, the 
canal somewhat more contorted and the insinuation in front of the lobe deeper, 
as in P. contortus. 
The ornamentation consists from the first volutions in oblique transverse costee 
and in spiral sulcations, which sometimes produce a more or less regular granulation. 
One row of such coarse granule is always separated near the suture. To this up- 
permost row follow transverse ribs, which occasionally are represented by elongated 
roundish tubercles only. On the last whorl a few slight sulcations cross the ribs, 
which at about one-fourth or usually one-fifth of the distance from the suture, 
as compared with the total height of this volution, are cut off by deep spiral sulci, 
so as to form six to ten rows of smaller or larger, rounded or flat, and more or less
