14 BLANFORD : GEOLOGY OF WESTERN SIND. 



of India. Several of the species common to the nummulitic rocks of 

 Europe are noticed towards the end of the brief geological summary, in 

 which the works of different explorers are noticed. 



After the geological Resume comes the description of the different 

 species, occupying 162 pages. Then there is an appendix in which 

 several species are added to the list, and this is followed by a Resume 

 General and a Tableau de la Faune fifummulitique cle I'Inde. The 

 Resume General treats of the relations between the Indian and the Euro- 

 pean nummulitic fauna, and between the fossils from different regions in 

 India, and it also contains a critical notice of several papers on Indian 

 tertiary geology not reviewed in the preliminary Resume Geologique. 

 The " Tableau" gives a complete list of all the Indian nummulitic fossils 

 known, with their distribution and references. 



In the Resume General, the authors again express their conviction 

 that all the marine tertiary fossiliferous beds of Cutch and Sind belong 

 to the lower tertiary " terrain/'' and that all should be comprised in the 

 " nummulitic group." Dr. Carter's classification of Grant's tertiary beds 

 of Cutch in the miocene is objected to, and it is shown that several of the 

 characteristic fossils occur elsewhere associated with nummulites. This 

 is quite correct ; for, as already mentioned, several of Grant's tertiary 

 fossils are from eocene beds. Messrs. D'Archiac and Haime add this 

 very important sentence : — " We consequently continue to begin the 

 middle tertiary formation here only with the lower»beds containing bones 

 of large mammals." 1 But still it is shown that the distribution of dif- 

 ferent kinds of nummulites may aid in establishing a succession of 

 different beds amongst the Indian tertiary rocks ; and it is suggested that 

 the Nummulites ramondi and N. leymeriei with Alvtolina ovoidea and 

 Operculiua canalifera, which abound with casts of Nerita schnideliana, 

 may characterize, as in Europe, the lowest bed ; that Nummulites lucasaua, 



1 This conclusion of Messrs. D'Archiac and Haime has unquestionably had a great influ- 

 ence in inducing European geologists and naturalists to class the Siwalik fauna as 

 miocene, in opposition to the views of Indian geologists. It is strange that the miocene 

 age of the Siwalik fauna should be still so strongly urged, although it was shown years since 

 that Messrs. D'Archiac and Haime were mistaken in supposing that miocene marine rocks 

 were wanting in Western India.
