clearly, that at least a part of those jurassic strata must belong to the Upper Jura, unless 
we presume that the faunae have followed laws of distribution quite different from those 
which were prevalent during the time of the jurassic deposits in Europe. 
Proceeding to the species, I will give brief distinctive characters of the new forms which 
T have described- There are of Phylloeeras, preserved in the Geological Survey Museum,— 
Phylloeeras disputabile, Zitt. (golden oolite of Keera hill near Charee; brown 
oolite of the Jooria hills), 
,, Lodaiense, Waagen, n. sp. (brown oolite of Lodai). 
„ Feddeni, Waagen, n. sp, (oolite with iron nodules near Dhosa). 
„ ptychoicum Quenst. (coarse iron sandstone of the Katrol range). 
„ Zignodianum, Orb. (golden oolite of Keera hill). 
Phylloeeras Lodaiense, Waagen, n. sp. Very closely allied to Phyll. disputabile, Zitt., 
but the furrows disappearing on the siphonal side and very deep near the umbilical 
margin; it has also much shorter and broader lobes than Phyll. disputabile. 
Phylloeeras Feddeni, Waagen, n. sp. Closely resembling Phyll. Homairei, Orb., but 
the umbilicus a little smaller and the external saddle finishing in three unequal leaves. It 
differs from Phyll. euphyllum, Ileum., by a little larger umbilicus and less developed third 
leaf on the external saddle. 
The genus Lytoceras has furnished, as stated before, only two species, one of them 
being new ; they are : 
Lytoceras Adeloides, Kudern. (golden oolite of Keera hill). 
„ rex, Waagen, n. sp. (sandy yellow rock, S. of Charee). 
Lytoceras rex, Waagen, n. sp. A specimen of 600 m m. in diameter. Inner whorls 
finely striated without any prominent ribs; body-chamber with a few prominent ribs, with 
broad smooth spaces betwoen them; ribs with 7 folds on each side. 
The species of ITaploceras which I have mentioned before is not determinable with 
sufficient certainty, as the last part of the body-chamber is wanting; but it is very probably 
Haploceras tomephorum, Zitt. (coarse sandy iron rock, S. of Boojooree). 
The genus Oppelia has furnished several well known European species of great interest, 
only two new forms were among the number. The species are: 
Oppelia subcostaria, Opp. (golden oolite, Keera hill). 
„ glabella, Leckenby (gray marl nodule, Keera bill). 
„ trachynota, Opp. (coarse sandy iron rock, Katrol range). 
„ Outchensis, Waagen, n. sp. (same layer and locality). 
„ plicodiscus, Waagen, n. sp. (rock indistinct, S. of Madapoor). 
„ cf. serrigera, Waagen (gray limestone, S. of Nurrka). 
Oppelia Outchensis, Waagen, n. sp. Very much like Oppelia compsa, Opp., however 
much smaller; the siphonal side rounded, granulated; tubercles on the body'-chamber scarce, 
distant, roimded; ribs entirely disappearing. 
Oppelia plicodiscus, Waagen, n. sp., belonging to the group of Oppelia subtililobata, 
W. and nearly allied to Opp. tenuilobata, Opp. The shell is small and covered with rather 
broad, strongly falciform ribs, which are a little swollen at the middle of the sides; near 
the siphonal margin a great number of very fine, short ribs, which are not in connection with 
the others, are visible.
