Of those species Pit. disputabile, Zitt., Zignodianum, Orb., and Lyt. Adeloides, Kud., 
arc known to be characteristic in the mediterranean province of the jurassic formation of 
Europe for a group of strata beginning with Bathoniau and most probably terminating with 
lower Oxfordian rocks. The following species indicate a much more narrowly limited hori¬ 
zon: Slept/., maerooephalum, Sehloth., tumidum. Rein., Grantauum, Opp., Perisph. spworhis, 
Neum., hracteatus, hvt-urp., fcnu/u-s, Opp., and Rchman/ti. Opp., all without exception in the 
central European province ai-e highly characteristic for the lower Kello vian beds, or the “ zone 
of St. macrocephalum” of Oppel. The Ammonite-fauna of the ‘Golden Oolite’ shows very 
little resemblance to the faunas of other localities, and iu fact there are only three species which 
are common to this layer and the brown oolite of Lodai and the Jooria hills ; those are Phyll. 
disputabile, St. macrocephalum (very rare at Lodai), and Polyphemus (very rare at Keera 
hill). It seems to me that the characteristic species of the Ammonite-fanna of this 
Golden Oolite appear again only at Kaora in Putchum, and at J umara, though similar rocks 
may he often represented in different horizons throughout the Kuteh jurassic territory.

The greater part of these species also occurs at the two next localities, and I shall, 
therefore, quote those occurring in the two latter immediately following.

There is, I think, hut little doubt that the Ammonite-fauna of these three localities in¬ 
dicates very closely the same geological horizon, particularly when we consider the small 
number of specimens (there are in our Museum not more than about 60 specimens preserved 
from all the three localities) which were examined, and that these have furnished so many 
identical species. 
Of the species noticed, the following are found in the European Jura: Pelt, athleta, 
Perisph. anceps and curvicosta ; all three are most characteristic forms of the upper Kello- 
way strata. 
The next localities which have furnished a greater number of species are Lodai and 
the Jooria hills. The rock containing the fossils is a very line, often sandy dark-brown
