A 7iew order of extinct Jurassic reptiles. 



In 1879, Prof. O. C. Marsh indicated a " new genus " of reptiles named 

 Gwlurtis, which he subsequently re-examined and considered to rejire- 

 sent a " new order," most nearly related to the Dinosaurians (A. J. S. 

 (3), xxi, 339-340); or, a little later, a "suborder" probably of the 

 " order Dinosauria" (A. J. S. (3), xxi, 423); and later still, an "order" 

 of the "subclass Dinosauria" (xxiii, 85), The new type is remark- 

 able for the hollowness of the vertebrae and the extreme lightness of 

 those bones, " the excavations in them being more extensive than in 

 the skeleton of any known vertebrate. There was, in fact, merely a 

 slender framework of bone to define the form and inclosing extensive 

 cavities." The ribs, too, of Coelunts are hollow, with well-defined walls 

 to their large cavities. The metatarsals were " very long and slender." 

 The genus is only known from various vertebrae representing the differ- 

 ent regions of the body, ribs, and metatarsal bones. It is inferred from 

 these that the animal had " a large and powerful neck, a trunk of mod- 

 erate size, and a very long neat tail," and it has been suggested that 

 the posterior limbs may have been larger than the anterior. "The re- 

 mains now known are all from the Atlantosaurus beds of the Upper 

 Jurassic of Wyoming." The name Coeluria has been proposed as the 

 ordinal designation. 



American Pterodactyles. 



The remains of Jurassic Pterodactyles found in the United States 

 hitherto have been fragmentary. Enough has been preserved, however, 

 to enable Professor Marsh to recognize in the Jurassic fossils species
