them over with bare mention, not having yet had time to 

 examine and compare tliem with other shells. One is a 

 Gasteropod, a Aatico2%sis appai-ently, which I will call 

 N. lilydalensis, if it should tnvn out to be new ; and the 

 other is a lamelli-branchiate shell, an Ambonychia, differing 

 from A. post-striata of Etheridge, and alluded to by Professor 

 Tate, as having a fenestrated ornament on the sides of the 

 valves. If Professor Tate has not already named it, and 

 will forgive my impudence, I will take possession of it in 

 the name of Victorian geologists and call it A. tatei, for I 

 am pretty sure we had found it long befoie he did. 



In concluding, I desire to-^ acknowledge my indebtedness 

 to Mt. D. Mitchell, the owner of the quarry, and also 

 to his foreman, Mr. J. Fuller, for statistical and other 

 information about the quarry ; to Mr. G. B. Pritchard, of 

 the Woi-king Men's College, for the loan of fossils ; and to 

 Mr. H. J. Stokes, organist of St. John's, Camberwell, for 

 the photogi-aphs of the quarry that have been exhibited in 

 illustration of this paper.
