TV.—Own tae Systematic Postrion or tHE Upper Creracreous 
Dinosaur ZTTANOSAURUS. 
By Baron Francis Norvcsa. 
EING prevented by other work from continuing at present my 
work on the Danian (Laramie) Dinosaurs of Transylvania, 
I wish briefly to draw attention to the fact that the Upper Cretaceous 
Titanosaurus, as known from the Montagne Noire in France and from 
the Cretaceous formation of Argentina, and perhaps also from East 
Africa (as already pointed out by Fraas), has nothing to do with the 
Sauropoda, but belongs to the Trachodontid Orthopods, as proved by 
the abundant Transylvanian material at my disposal. 
Without attempting to enter at present into the question of generic 
identity of the American, African, and European Upper Cretaceous 
Titanosaurs, I wish to point out that the Montagne Noire and the 
Transylvanian Reptiles are generically identical and must be known 
as Telmatosaurus, the name Z?tanosaurus being only applicable to the 
English Wealden Sauropod described in 1887 in the Quarterly 
Journal of the Geological Society. The striking survival of 
a Sauropod so late as the Danian may therefore be questioned, and 
the time-table in that most interesting recent paper ‘‘ Distribution 
and Range of Dinosaurs’’, by Professor R. 8. Lull, must therefore be 
modified accordingly. 
The Zelmatosaurus, to the tail of which the ‘ Z7tanosaurus vertebre’ 
belong (as proved by Transylvanian undescribed material), is a heavily 
built Trachodontid animal, with a straight Stegosaur-like femur 
(small fourth trochanter), a heavy and relatively strong humerus, 
nearly solid bones, and probably guadrupedal locomotion. Being the 
only Iguanodontid animal which we can suppose to have secondarily 
descended on its fore-legs (as Stegosaurus, etc., had done after passing 
a Scelidosaurus-like stage of evolution), Zelmatosaurus deserves special 
attention. Since Zelmatosaurus is accompanied in Transylvania by 
another Dinosaur (Mochlodon) which, according to its degree of 
specialization, would rather correspond with the Lower Cretaceous 
than with the Danian, and since the same is also true of the 
Telmatosaurus itself (see Sauvage’s remarks on Teématosaurus = 
Inimnosaurus in Rev. Crit. de Paleozoologie), the Dinosaurian fauna 
of Transylvania bears the same relation to the American Laramie 
fauna as the recent fauna of Australia to that of the recent fauna 
of the rest of the world.

Lryn-y-groes Lode.—About 500 yards east of the Clogau lode, 
there is a parallel lode which has been worked for copper. Striking 
50° east of north, its outcrop may be traced for about 14 miles; its 
width is very variable. Chaleopyrite and pyrites and a little gold 
are present in the quartz. The lode is confined to the Vigra Beds,
