It is only with Group a of Section II. that we are at present 
concerned. This I regard as equivalent to part of Tenmocheilus, as 
above defined, and Dr. AVaagen’s remarks respecting the range of 
this group in India are of so much interest, that I give them in 
ex'tenso : — 
“ The oldest species which I am inclined to unite with the 
Tuberculati is yaut. subtuberculatus, Sandberger, out of rocks of 
Devonian age. The characters of the group are, however, not yet 
Dr. Waagen is of opinion that these beds, though containing a fauna which 
in its general aspect is Carboniferous, yet show that the fossils (especially the 
smaller and less conspicuous ones) are of Permian type, and at last, he says, 
one arrives at the conviction that the beds contain a Permian fauna “ richer in 
forms and richer in consjjicuous species than any that has been described up to 
the present in the whole world.” 
“At the same time,” he adds, “ its close relationship to the Carboniferous 
fauna cannot be denied ; and the thought cannot quite bo rejected that the 
singular deviation of the Euroj^ean Permian fauna from the Carboniferous type 
is caused more by local influence than by a thorough change of the organic 
life over the whole world, and that in reality the Permian organic life is in by 
far closer connection with the Carboniferous than was anticipated by Mur- 
chison.” 
The name “ Productus -limestone ” can now, adds Dr. Waagen, be applied 
to the whole series enumerated in the above table, and “ be considered as a 
synonym of ‘ Carboniferous ’ in the widest sense, if one considers the Permian 
as nothing but a subdivision of the Carboniferous, as Bunter Muschelkalk is a 
subdivision of the Trias.”
