 Pectoral nearly two-thirds of same. Distance of dorsal from 

 caudal less than half the depth of the peduncle. Scales moderate, 

 ciliated. Kays of vertical fins and of caudal scaly. Profile of head 

 deeply emarginate over the orbit. Interorbit very narrow, elevated, 

 naked. Caudal cuneiform. Dorsal rises opposite front margin 

 of upper eye. Eyes nearly in the same vertical, lleddish-grey

Long 7 V'. Zo(7. MoretonBay. Type in Queensland Museum.

 this fish diverges considerably from typical forms of Pleuronectes 

 to which however it belongs rather than to any other group 

 known to me. In this genus therefore I leave it for the present. 



Physical Structure axd G-eology of Australia. 



By the Eey. J. E. Texiso2s'-Woods, E.a.S., E.L.S., &c. 



The Physical Geography of Australia gives a key to its 

 G-eolog}'. It is an immense table land, with a narrow tract of 

 land sometimes intervening between the edge of this elevated 

 area and the sea. The east side is the highest, averaging about 

 2,000 feet above the ocean. The west side is not more tlion 1,000 

 feet above the same. The north is a little higher. The south 

 side is either level with the ocean, or abuts in cliffs upon the sea, 

 ranging from 300 to GOO feet in height. The general character 

 of all the seaward side of the table land is precipitous ; but on 

 the south-east angle of the continent the tabular form disappears, 

 and there is a true cluster of mountains (the Australian Alps), 

 whose highest elevation is a little over 7,000 feet. This group is 

 near the sea (Bass' Straits), and then after an interval of about
