1860 of large numbers of Teritary mollusca from Australia and New 
Zealand, has made it possible for Professor Harris to present a very 
exhaustive review of the subject, the Gasteropoda particularly being 
described in great detail. The fine state of preservation of the speci- 
mens has led the author to consider the several forms both from an 
ontogenetic and phylogenetic standpoint, and as so little work of this 
character has been done on the Gasteropoda, hitherto, it must prove 
of fundamental importance in the systematic classification of this class 
of the mollusca. 
The book contains a complete synonomy ofall the forms catalogued, 
together with a description of such new material as the Museum pos- 
sesses. The admirable figures which accompany the volume show in 
great detail the protoconchs of many of the Gasteropod types. 
This report presents the first thoroughly systematic treatment of 
the Tertiary molluscan faunas of Australasia and will be of great serv- 
ice to the student of Tertiary mollusca in other portions of the world. 
Volume I -will be succeeded by others in which the large Tertiary 
collections of the British Museum from other lands will be minutely 
described. There is no man better able to undertake this task than 
Professor Harris, as he is intimately acquainted with the Tertiary in 
many portions of the world, and probably has a more comprehensive 
knowledge of the Tertiary of central and western Europe than any 
one living. He has published an important memoir on the Eocene 
geology and paleontology of the Paris Basin, besides making contri- 
butions to the Tertiary of England. 
The future publications of this series will be awaited with much 
interest by all students of Tertiary paleontology.
