0£ the Vertehrata, the fishes were abundantly represented by 

 species belonging to the existing Order Teleostei, and remains 

 of a few Ganoids, and of a large number of Placoids have also been 

 discovered in rocks of this Period. 



The modern Orders of the Bepfilia — CheJonia, Grocodilia, Opiiidia, 

 and Sauria {Lacertilia~), were numerously represented; but the cha- 

 racteristic types of the Mesozoic Age — the Flesiosauria, Fterosauria, 

 Ichthyosauria, and Dinosaurin had passed away. 



The birds include species belonging to almost all the existing 

 Orders. 



The Mammalia, which in the Mesozoic Age was represented only 

 by the Marsupialin, one of the lowest Orders of the whole Class, had 

 now become the dominant race, and included types of most of the 

 existing Orders, viz. : — Marsupialia, Chiroptera, Insectivora, JJngulata, 

 Cefacea, and Carnivora. There are also traces of the existence during 

 this Period of animals belonging to the Rodentia and Quadrumana. 



The change in the conditions of the Vegetable Kingdom, which had 

 commenced before the close of the Cretaceous Period,* still continued; 

 and whilst the Cycads had almost disappeared, and the Conifers were 

 no longer the predominant group, the Angiosperms and Monocotyledons 

 were rapidly increasing in number and variety, and included the great 

 majority of the plants of the Period.

Antennfe : the club much narrower and longer than in Percnodaimon Pluto, but not 

 so narrow or long as in Erebia Blandina. 



Eyes naked. 



Labial palpi rather longer, and densely clothed with much longer stiiRsh hairs than 

 in P. Pluto : the hairs of the tip forming an obtuse-pointed pencil. 



Body and legs clothed with rather longer hairs than in P. Pluto. 



Wings entire. Primaries rather more elongate, and hind margin more oblique than 

 in P. Pinto ; the nervures and discoidal cells of both the primaries and 

 secondaries very similar to those of P. Pluto, except that in P. Pluto the first 

 (c. fig. 3) sub-costal nervure is absent, and the space between the externo-medial
