APPENDIX. 



Additional Evidence of the Genus Dromornis in Australia. 

 By Prof. Owen, C.B., F.B.S., F.Z.S., &c. 



[Plate XXXIIL] 



Received January 25tli, 1877. Bead March 6th, 1877. 



A FEW weeks ago 1 was favoured with a letter from an esteemed correspondent in 

 Australia,- the Eev. W. B. Clarke, F.G.S., dated " Branthwaite, North Shore, New South 

 Wales, 11th October, 1876," inclosing a photograph of a portion of the pelvis of a huge 

 bird, which bird had been found at a depth of from 150 feet to 200 feet in what is 

 called the ' Canadian lead,' " the bed-rock of which, at this place, is a palaeozoic lime- 

 stone, much waterworn and cavernous." The locality is " in the county of Phillip, not 

 far from Mudgee, on the I'oad to Gulgong." 



Mr. Clarke promises to send a cast of this specimen ; but I will not delay to notice 

 the discovery, because the photograph and the given dimensions show the specimen to 

 have formed part of a bird's pelvis as large as that of the Binornis elephantopus ; and 

 I have received, firom another and distant locality, a fossil bone which enables a more 

 instructive and decisive comparison to be instituted between it and the corresponding 

 part of the skeleton of the Binornis most nearly corresponding with it in size. 



This bone was sent me from the province of South Australia, and was found in the 

 " Mount Gambier range." 



It is the lower portion, with the articular end a little mutilated, of a left tibia of a 

 flightless bird (Plate XXXIII.), and corresponding in size with the same part in Binornis 

 elepJiantojms^, and rather larger than that of Gastornis parisiensis^. 



As the modifications of the distal end of the tibia in birds are more salient and 

 characteristic than those of the femur, the present specimen is valuable as a test of the 

 conclusions drawn from the fossil femur of the large bird from Australian drift de-
