Professor 0. C Marsh— European Dinosaurs. 7 



of memoirs on the different groups of this subclass of extinct 

 Keptilia. 



London. — I began my investigations in the British Museum in 

 London, a great treasure-house for fossil reptiles, to which I have 

 long made frequent pilgritnages. This time the Dinosaurs were 

 seen to better advantage than ever before, but of new or unknown 

 forms I found that few had been added to the collection since 

 my visit two years ago ; and I consoled myself with the other 

 extinct Keptilia, and especially with the new fossil birds and 

 mammals from South America. 



-6"^. Petersburg. — In St. Petersburg I hoped to find many Dino- 

 saurian remains, as here had been brought together an abundance 

 of fossil treasures from various parts of the Russian Empire, which 

 I knew must contain many forms of this group. In the four 

 principal museums of the city, however, I could find no bones 

 of Dinosaurs on exhibition, nor could I learn from any of the 

 museum authorities that such remains had been recognized among 

 the specimens received, neither could I find any such fossils myself 

 among the debris of the collections, so often a rich repository 

 for new or inconspicuous specimens. This was true also of the 

 smaller collections visited, and I was at last forced to admit that 

 here, at least, the Dinosaurs of Russia, like the snakes of Ireland, 

 were conspicuous only by their absence. 



Moscoio. — This opinion was not changed by a visit to the rich 

 geological collections of Moscow, which I examined with care ; 

 although other fossil vertebrates, including many reptiles, were 

 abundantly represented. I was assured, moreover, by various 

 Russian paleontologists, that in other museums of the empire or 

 in the known localities they had seen no Dinosaurian remains. 

 This vain quest, however, only proves that the discoveries are 

 yet to be made, and I confidently expect them at no distant day, 

 since in almost every other part of the world Dinosauria have 

 already been brought to light. In Northern Europe west of Russia, 

 and in North America to the east, these reptiles were especially 

 abundant, and the vast territory intervening must contain numerous 

 Dinosaurs, including many new forms of the group. 



Vienna. — In Vienna I knew that my friend Professor Suess had 

 a large collection of Dinosaurs in his museum to show me, and 

 I spent several days there in their investigation. This collection 

 was of special interest to me, as it was from the Gosau fresh- 

 water deposits, which, as a student, years ago, I explored mainly 

 in the expectation of finding Cretaceous mammals ; and I was 

 not without hope of still detecting such remains during my present 

 visit, as here were the localities where they were, in my judgment, 

 most likely to be found in Europe. The Dinosaurs I examined were 

 from Neue Welt in this formation, and were of great interest. They 

 had all been studied by Bunzel, Seeley, and others, who had recog- 

 nized ten or twelve distinct genera and many species among them. 

 I could find, however, not more than a quarter of this number, and 

 among these I found no indications of the Ceratopsia, which from
