PREFACE. 



THE following memoir opens a new series of the Palaeontologia Indica, Series 

 XVI, comprising a description of the fossils found in Baluchistd,n. It is con- 

 templated to publish an account of the rich collections of fossils in a series of 

 monographs, each of which contains the description of the fossils, collected at a 

 certain locality, in certain beds. By adopting this plan it will not only be possible 

 to give further additions, if more and better preserved specimens are discovered at 

 another locality in beds of the same age, without breaking the continuity of the 

 publication, but as each monograph forms a whole in itself, the former drawback 

 of years lapsing before the completion of a monograph will be avoided. 



The first part of Series XVI comprises the Jurassic Tauna of Baluchistdn, and 

 the present monograph deals with the fauna of the Kellaways from Mazdr Drik. 



The second part of Series XVI will contain the Cretaceous Fauna of 

 Baluchistdn and the first monograph which will appear shortly, and will contain 

 the description of the uppermost cretaceous fauna.
