most Mammalian of all the Reptilia. This fact is alone suffi- 
cient to discredit Dr. Kiikenthal’s theory. 
Dr. Kiikenthal seems to credit the advocates of primitive 
monophyodontism with supposing that the present single 
dentition of the Cetacea is an unmodified survival of the 
earliest monophyodont condition; but this is not the case, 
that view having never. been taken, so far as I know, by 
any one but Baume, and by him on the basis of a wholly 
different theory. I myself * have supposed the ancestors of 
the Cetacea to have passed through a more or less diphyo- 
dont stage, and to have afterwards lost one of their two sets 
of teeth. 
Dr. Kiikenthal is to be congratulated on the brilliant 
results that have attended his investigations, and I trust that 
he will continue his efforts to find out the true homologies of 
the different teeth, and thereby facilitate the work of those 
who for systematic purposes need to have correct names under 
which these important organs can be compared and described. 
XLIX.—On some undescribed Cicadide, with Synonymical 
Notes. By W. L. Distant. 
I HAVE had submitted to me for identification a number 
of species belonging to this family contained in the collec- 
tions of the South-African Museum at Cape Town and 
the Australian Museum at Sydney. The new species from 
these sources and others which I have recently received 
are here described, with a few synonymical notes and 
corrections resulting from some perfunctory and hasty work in 
other quarters. The legacy of bewilderment left to students 
of the Cicadide by the late Mr. Francis Walker is already so 
sufficing that it is earnestly to be hoped that such difficulties 
be not increased by other writers unfamiliar with the 
family. Like all other zoological groups Cicadide require 
study, but have, unfortunately perhaps, been as much 
obscured in printed matter as has proved to be the fate of 
most families of the Rhynchota, 
CrcaDIN”.
