On some Marine Fossils from the Miocene of Upper Burma, by 

 Dr. Fritz Noetling, F. G. S. Paleontologist, Geological 

 Survey of India (with 10 plates). 



INTRODUCTION. 

 With the exception of two species, Batissa crawfurdi and Batissa 

 petroleiy which have been collected near Yenangyoung, all the fossils 

 described on the following pages have been collected by me near 

 Yenangyat and Minbu while surveying the oil-bearing tracts in 

 Upper Burma. It may perhaps seem inadvisable to select the fauna 

 of these two localities for description, considering that large collec- 

 tions of fossils from the miocene of Lower Burma, made by Messrs. 

 Theobald and Fedden are waiting to be described, and that it would 

 be preferable to describe the Upper Burma fossils together with 

 those. This being, however, a task which will occupy several years, 

 and as it appeared necessary to arrive at a more definite conclusion 

 regarding the age of the petroleum-bearing strata, I thought it well 

 worth to examine this fauna and to describe it in a separate paper, 

 and i am glad to say that the result has fully justified the expectations. 

 The geological position of the strata in which these fossils have 

 been found, may be defined in a few words : Batissa crawfurdi and 

 Batissa petrolei have been found in the ferruginous conglomerate or 

 the zone of Hippotherium antelopinum near Yenangyoung ; it is un» 

 questionable that this horizon is younger than that in which the 

 fossils from Minbu and Yenangyat have been found. The latter 

 came from strata which are immediately above the oil-bearing beds 

 at Yenangyat, and perhaps a couple of hundred feet above the same
