have joined the jaw. The width of the crown is 07 inch, and its height 
0'4 inch. 
The general form of the ci’own of this tooth, and its wear, is much like that 
of the incisor of Oapitodm tr uncat us ‘ ; the crown is, however, proportionally much 
wider in the Indian than in the European tooth. The other European species 
have still narrower incisors. The Indian tooth belongs apparently to a distinct 
species, which I propose to name G. indicus. 
The strata from which the tooth was obtained are probably of upper Eocene 
age. The genus Capitodus seems to be closely allied to the living Sparoid 
Sargiis,^ but is distinguished by its broader incisors. The Indian species carries 
the genus back to the upper Eocene.

In my Flora of the Talchir-Karharbari beds, I had occasion to notice wbat 
was then known regarding the systematical position of the genus Noggeratliia, 
and also to show the reasons why I thought that certain leaves of the Indian 
coal beds, described as Nvggerathia, differ from this genus in the proper sense; 
I accordingly named them Noggerathiopsis, leaving them wdth the Cycadeacea. 
At that time I could not refer to the Australian Noggeruthia ; but later exami¬ 
nation and comparison have shown that the Australian leaves, also called Nog- 
gerathia, do not generically differ from the Indian Noggerathiopsis, and have 
therefore to be also classed Avith this genus. 
In India the leaves seem to represent one species only, with about one or two 
varieties; they are knoAvn from (a) The Talchir-Karharbai group, and (&) from 
the Raniganj-Kamthi group. 
In Australia this genus is known to begin in the lower coal-measures (below 
the first marine fauna), from which I described one species as Noggerathiopsis 
prisca. It is more numerous in the upper coal-measures (Newcastle beds), from 
which two species of Noggerathia w^ere described by Dana; they should now, 
of course, be classed wdth Noggerathiopsis. 
There is a close representative of this genus in the Siberian Jura, i.e., in the 
Kusnezk basin of the Altai, and on the Lower Tunguska (tributary of the 
Yenissei river). From the foi-mer place, two species of Noggerathia were describ¬ 
ed by Prof. GbpperP as Nogg. eequalis and N. disfans, and the formation from 
which they came was supposed to be Permian.
