Notice of New Dinosauria. 331 



From Asia and Africa, also, a few remains of Dinosaurs 

 have been described, and the latter continent promises to yield 

 many interesting forms. Characteristic specimens, represent- 

 ing two genera, one apparently belonging to the Stegosauria, 

 and one to the Theropoda, are already known from South 

 Africa, from the region so rich in other extinct Reptilia. 



From Australia, no Dinosauria have as yet been recorded, 

 but they will undoubtedly be found there, as this great group 

 of Reptiles were the dominant land animals of the earth, dur- 

 ing all Mesozoic time. 



Art. XXXV. — Notice of New American Dinosauria ; by 

 O. C. Marsh. 



In the large series of Dinosaurian remains brought together 

 by the writer, in the last few years, and now under investiga- 

 tion, there are a number of new forms, some of which are 

 briefly noticed below. These will all be fully described and 

 figured in the memoirs now in preparation, by the writer, for 

 the United States Geological Survey. 



Anchisaurus major, sp. nov. 



The remains of this reptile are from the sandstone of the 

 Connecticut River valley, which has long been known for the 

 great variety of footprints it contains, especially those sup- 

 posed to have been made by birds. The extreme rarity of any 

 bones in these beds is equally well known, not more than half 

 a dozen finds having yet been made, and only a few of these 

 of much scientific interest. A portion of a skeleton found 

 near Springfield, Mass., and described by Hitchcock, in 1865, 

 as Megadactylus, has hitherto been by far the most important 

 of these discoveries. It is a typical member of the order 

 Theropoda, and has apparently for its nearest allies in the old 

 world, Thecodontosaurus, from the Trias of England, and 

 Massospondylus, from the same formation in South Africa. 



The remains here described represent a later discovery, in 

 1884, near Manchester, Conn., in essentially the same horizon 

 as the Springfield specimen. They indicate an animal of 

 larger size, but in many respects nearly allied to the one
