274 Reviews — Australian Fora))iiitifera. 



as many animals and plants of kinds that are characteristic of the 

 accepted ' Permian ' age are associated in these strata with the 

 characteristic fossil fauna and flora of the ' Carboniferous ' period, 

 this composite formation of ' Carboniferous ' modified by ' Permian ' 

 (in India, America, Africa, and Australia) has been widelj?^ referred 

 to by geologists as the ' Permo-Carboniferous.' We are glad to 

 see that in this Monograph the logically correct term ' Carbo- 

 Permian ' is used by Messrs. Chapman and Howchin. Professor 

 David goes on to compare the foraminiferal horizons of New South 

 Wales with those known in Tasmania and West Australia. 



From the descriptive part of the Monograph (pp. 1-32), we learn 

 that the specimens of rock and detritus collected from these two 

 special zones yielded 14 species of Foraminifera from Pokolbin 

 and 15 from Wollong, and that 6 occurred at both places. These 

 35 species are referable to the following : — 



. ) Lituolidse ... 15 ,, I 



ARENACEOUS ^ TextularidiB . . . 4 „ > Found at Pokolbin and Wollong. 



Hyaline 



Lagenidse ... 11 

 Kotalidse ... 2 



These 35 species are relegated to 23 genera, all of which have 

 long pedigrees originating in Paleeozoic times. Of the species here 

 indicated, their range in time, for the Northern Hemis^^here, appears 

 to be as follows : — 1 is otherwise known only in the Recent state ; 

 1 in beds of Tertiary age ; 3 occur in Cretaceous and 3 in Jurassic 

 rocks ; 3 in the Rhgetic series ; 1 in the Trias ; 5 are known in the 

 Permian ; 8 in the Carboniferous ; and some of these last are even 

 of Silurian age. 



Thus these Australian ' Permo - Carboniferous ' deposits com- 

 prehend not only Upper Paleeozoic fossils, but even several 

 characteristics of Mesozoic and Cainozoic times. 



We congratulate the Geological Survey of New South Wales on 

 the good results of having obtained the co-operation of Messrs, F. 

 Chapman and W. Howchin in working out the natural history of 

 the two special zones of Foraminifera in the Australian Carboniferous 

 series. The authors of the Monograph are experienced microscopists, 

 and have a wide knowledge of the recent and fossil Ehizopods. 



Special notice is made at page 20 of (1) the relative proportions 

 of different kinds : (2) the occurrence of the same Upper Palgeozoic 

 forms in the Southern and the Northern series ; and (3) the few genera 

 that are apparently confined to strata of the particular series ; 

 (4) nine of the Australian species are regarded as new. 



A very useful bibliographical list of memoirs having reference 

 to Permian and Carboniferous Foraminifera is given at pp. 21, 22. 



Mr. Chapman has carefully drawn 40 figures for the 3 plates, 

 and five sections of the Pokolbin rock for plate iv, in a very 

 trustworthy manner, without any unnecessary artistic niceties.
