SPECIMENS.)

In a previous paper (read Sept. 29), on a Labyrinthodont fossil 

 from Biloela (p. 'J 31 of this volume), some expression was given of 

 an expectation that more remains of the same character would be 

 forthcoming before very long. But the writer was nevertheless 

 rather astonished to learn (Nov. 30), from Mr. C. S. Wilkinson, 

 Government Geologist of N.S.W., that a 'Baby Labyrinthodont ' 

 had just been met with in a cutting on the Northern Railway, 

 and to have his anticipations so suddenly realized. Besides this 

 fossil there have turned up, among the collections of the Geological 

 Survey Department, two others, one, an unmistakable fragment of 

 the jaw of a large Labyrinthodont, with teeth so much weathered 

 away as to display their internal structure ; the other, a portion of 

 a smaller individual, showing the proximal portions of some 8 or 9 

 ribs, together with the vertebrae to which they belonged, and with 

 considerable remains of integumentary structures, which seemed 

 to the writer to indicate that it also belonged to the Labyrinthodont 

 type. Of this more anon. Confining our attention in the first 

 instance to the ' Baby Labyrinthodont,' it is worth while to state, 

 for the information of collectors, and as helping to determine the 

 exact horizon of the deposit, that this extremely interesting frag_ 

 ment was discovered during the excavations upon the railway now
