The relationships of the ammonite fauna of the Tr ee 
Cretaceous ‘a name given to the whole series of the coastal 
Cretaceous) to those “of other areas both in Europe and else- 
where have been studied and discussed by Kossmat* at great 
length and after a detailed study of fossils from several areas 
he finds that “the fauna of southern India comprises the most 
important types of the two great areas (the Indo-Pacific and 
the Atlantic and thus serves as a connecting link between

remarkable affinities to the European fauna, especially if we

of silts and shales containing numerous fossils, particularly 
the Ammonites. The ge eneral” aspect of the cephalopod fauna 
of the Utaturs according to H. F. Blanford 3 “ recalls the Gault 
of Europe” and he assigned to the Utaturs “a position mid- 
way in the Cretaceous—about Gault and Greensand.”” The 
most abundant as well as the most characteristic Ammionite 
of the lowermost Utaturs is Ammonites inflatus, Sow., a species 
remarkablein having a very wide geographical range, identical 
forms being found in several widely separated areas, including 
Central Europe. As Stolickza* has observed the species 
teristic species of the Gault in almost all the European 
provinces’ and in England it occurs in the Gault and 
Greensand, as also in the Albian of France. More recent 
studies of the Cretaceous deposits and their Ammonites have 
shown that Ammonites inflatus, identical in character with the 
Indian forms, was quite abundant even in the Lower and Middle 
Ganlt of England’ and there is good reason to believe that 
the form had come into existence even duri ing the times of the 
Lower Greensand. Messrs. Kitchin and Pringle, in their study 
of the Gault deposits of England find Ammonites ie as 
the most dominant Ammonite in the lower zones of the upper
