ceous Mammalia he was convinced the number of species would be 
increased rather than diminished. 
In respect to the tooth considered possibly reptilian by Professor 
Osborn, he now had a specimen showing it to possess a double fang, so 
its mammalian character was established. He criticised the use of 
Multituberculata fora group of mammals, and defended the use of a 
term applied by himself some years previous to the establishment of 
the one used instead by the author of the paper. 
Dr. Theodore Gill spoke in reference to nomenclature and the value 
of making priority of proposal of a name the established law in 
zoology. He believed the proposal of the name, when it was under- 
stood to what group or genus or species it was intended to be applied, 
was of more value than a strict definition. He cited several examples 
of defective definition ; but where the animal to which the term had 
been applied was well known, he believed it should be recognized.—
