8 Professor 0. C. Marsh — European Dinosaurs. 



the published figures and descriptions I supposed to be represented 

 in this collection. The Dinosaurs with dermal armour which I saw 

 all pertained to the Stegosauria, and two distinct genera among them 

 were more nearly like Scelidosaurus of the English Jura and Nodo- 

 saurns of the American Cretaceous than any others with which I am 

 familiar. This collection contained the only Dinosaurian remains 

 I could find in Vienna. 



Munich. — I next went to Munich, which, under Professor von 

 Zittel, has become a great centre for palaeontology. I found that the 

 gem of the collection is still the unique Compsognathns, which iu 

 several previous visits I had studied with care. A re-examination 

 impressed me even more with the fact, that this is one of the most 

 perfect and interesting vertebrate fossils yet discovered, and no other 

 example of the genus is known. It was in this unique specimen 

 that years before I had detected the embryo, and this fossil still 

 affords the only known evidence that Dinosaurs were viviparous. 

 I could find no other Dinosaurian bones of interest in the Munich 

 collection, the new features being mainly numerous fine specimens 

 of Mosasauria from America, and some interesting remains of 

 Hesperornis and Baptornis from the same horizon in Kansas. 



I was much pleased to see here the new Jurassic fossils collected 

 by Nansen in 1896, at Cape Flora, in Franz Josef Land. These 

 interesting remains are now under investigation by Dr. J. F. 

 Pompeckj, assistant in the Munich Museum. I could detect no 

 vertebrate fossils among them, although various indications favour 

 their presence in this fauna. 



Paris, — My limited sojourn in Paris gave me no opportunity for 

 a careful examination of the museums there, but I could learn of 

 no recent additions of Dinosaurian remains since my last visit. 



Caen. — I next went to Caen, in Normandy, to see the famous 

 Dinosaur Poikilopleuron, so well described by Deslongchamps many 

 years ago. Through the kindness of my friend Professor A. Bigot, 

 I had a good opportunity to study this unique specimen, which of 

 late has been regarded as identical with the Megalosaurus of Buck- 

 land, the first genus of Dinosaurs described, and one about which 

 little is yet known. 



Among the undetermined material of this museum, I was greatly 

 pleased to find the genus Pleuroccelus well represented by character- 

 istic fossils, and from a well-defined Jurassic horizon in the vicinity 

 of Havre. The species appears to be a new one, somewhat smaller 

 than Pleuroccelus suffosus from the Kimmeridge of Swindon, England.^ 

 It resembled still more closely Pleuroccelus nanus, which I have 

 described from the Potomac formation of Maryland. 



Pleuroccelus is one of the most characteristic genera of the Sauro- 

 podous Dinosauria, and its value in marking a geological horizon 

 should therefore have considerable weight. It is now known from 

 the two European localities mentioned above, both in strata of 

 undoubted Jurassic age. The same genus is well represented in 



' Lydekker records a Wealden species, Pleuroccelus valdensis, in Quart. Journ. 

 Geol. tioc, 1890, toI. xlvi, p. 182, pi. ii.
