D. Carboniferous Period (p. 349). 



The annexed figure (Fig. 985) represents, twice the natural size, a Neuropterous 

 Insect, the Miamia Bronsoni D., (Silliman's Jour., xxxvii. 34, 1864,) found by 



J. G. Bronson in an iron-stone concretion at Morris, Illinois. Other concretions 

 of the same bed contain coal-plants, and some have afforded Amphipod Crusta- 

 ceans. The anterior feet appear to have been grasping or prehensile feet, as in 

 the Mantispids. The large joint was armed with long slender spines. 



E. Jurassic Period (pp. 453 and 462). 



The newly-discovered long-tailed or reptilian Bird of Solenhofen — Archcsopteryx 

 macruru8 Owen — is represented on the following page, reduced to one-fourth, 

 from a plate in the Intellectual Observer for December, 1862 (London). The tail 

 is 11 inches long, and 3£ inches broad. It consists of 20 vertebrae, and has a row 

 of feathers along the sides. These feathers are in pairs corresponding with the 

 number of the vertebrae, and diverge from the axis at an angle of 45° ; the last 

 pair extends backward nearly in a line with the last vertebra, and 3£ inches be- 

 yond it. The wing appears to have had a two-jointed finger. The breadth of the 

 wing was made by feathers as in Birds, and not, as in a Pterodactyl, by an ex- 

 panded membrane. The feet are like those of Birds. 



In the Reptilian age, nearly all the Vertebrates had some reptilian features ; 

 and the Birds were no exception. As the Palaeozoic Ganoids had vertebrated 

 tail-fins, so the earliest of Birds had long vertebrated tails. They are interme- 

 diate between modern Birds and the inferior class, Reptiles, just as Amphybian 

 Reptiles are so between true Reptiles and Fishes, and Marsupial Mammals be- 

 tween ordinary Mammals and the oviparous Vertebrates.
