is the same break between the Secondary and Tertiary series. Mr. 
Woods is of opinion tbat the weight of evidence is against the 
theory advanced by some tbat any part of tbe continent bas remained 
dry laud since the Mesozoic period. 
Mr. R. M. Jolinston’s paper deals witb tbe stratigraphical Order 
of tbe Table Cape Tertiary series. Tbe surrounding conntry bas 
been subjected to a large amount of denudation, a capping of basalt 
and basaltic tuff, 80 feet thick, acting as tbe protecting medium in 
tbe immediate vicinity of the Cape. Beneath this cap is a series of 
beds of white and grey calcareous sandstone, termed by tbe author 
tbe “ Turritella Group ” from the prevalence of T. Warburtonii, 
Tenison- Woods. Tbe deposit next in Order of succession below 
tbe “ Turritella Group ” consists of an “ irregulär agglomeration of 
shells, bound up in a matrix of ferruginous-looking mud,” and is 
called tbe “ Crassatella bed.” Tbe fauna of both groups is a copious 
one, and they are respectively characterized more by tbe prevalence 
of certain forms in each, and the gradual diminution or increase of 
these, as the case may be, as we pass from one series to the other, 
than by tbe restriction of species to each bed. All tbat can be said 
is tbat the Turritella Group and Crassatella bed were accumulated 
under somewbat different conditions to one anotber. Tbis marine 
deposit rests upon a bigbly indurated conglomerate floor, whicb 
probably corresponds to a conglomerate described by Mr. Gould on 
the Dial Bange, as of Silurian age. At the Table Cape tbis con- 
glomerate appears to rest unconformably on slate rock. 
Tbe species obtained by Mr. Johnston from tbe Tertiary beds of 
Table Cape, 150 in number, were examined by tbe Bev. Mr. Woods, 
and the new species described in tbe tbird paper above cited. 
Eighty of these were found to be new, of whicb, 10 per cent. 
are existing forms, and appear to indicate tbe Table Cape beds 
as a deposit of tbe Laminarian zone. Tbe Foraminifera are 
abundant, and amongst tbe Corals are tbe only true reef-builders 
met witb in the Australian Tertiaries. Tbe Brachiopoda are also 
abundant, and tbe Echinodermata numerous, presenting some new 
forms, whilst on the other band the Polyzoa are scarce, a marked 
contrast to similar beds in South Australia. Eliminating tbose 
fossils peculiar to tbe Table Cape beds, tbe majority are identical 
witb those of tbe S. Australian so-called Miocene, there being a 
greater resemblance between tbe two deposits on each side Bass’s 
Straits, than between tbe existing Molluscan faunas of tbe two 
coasts. The new species described by Mi\ Woods are divided as 
follows : — Gasteropoda, 48 or 49 ; Lamellibranchiata, 9 ; Polyzoa, 1 ; 
Corals, 2 ; and by Mr. Johnston, Echinodermata, 1. 
Tbe Polyzoon described is both a new genus and species — Buslcia, 
(B. typica. Tenison-Woods). We would merely point out that tbe 
term Buslcia has already been made use of in a generic sense by tbe 
late Mr. Alder for a recent Zoophyte, whicb be named Buslcia nitens. 1
