except along the bed of the stream, where they are much concealed by 



thick deposits of calcareous tufa ; and I have been unable, after 



the closest search, to identify the fossiliferous bed of Padaukpin 



anywhere else in the neighbourhood, or even to ascertain its 



position relative to the nearest outcrops. The 

 Character of outcrop. .. . . , , . , . 



portion of the bed exposed is about 5U yards 



in length, extending northwards from the west gate of the village, 



and a thickness of not more than 6 feet or so is visible. The 



rock has a gentle dip eastwards, which is that of all the outcrops 



seen in this direction for several miies, as far, in fact, as the base 



of the great scarp crossed by the railway at Kyauk-kyan. 



The fossils from this locality, described and figured by Mr. 



, , Cowper Reed, leave no room for doubt as to 



Age of Padaukpin reef. , . . . . , . t , 



the age oi the bed m which they are tound. 

 In an exhaustive summary of the results of his investigation of 

 the collection Mr. Reed comes to the conclusion — 



That there cannot be any hesitation in regarding the Padaukpin beds as 

 homotaxial with the lower part of the middle Devonian or Calceola stage of 

 Western Europe . . . for all the characteristic fossils of this stage (Calceola 

 sandalina, Cyrtina heteroclita, Ortholhetes umbraculum, etc.) are specially abundant 

 and there are very few definitely recognised species which are only known from 

 higher middle Devonian beds." (Op- cit, p. 144.)

 specially characteristic of, the uppermost zone of the Calceola" stage 

 in Western Europe are marked U, while the species enumerated in the 

 third column do not occur in Europe below the upper part of the 

 middle Devonian, or belong to higher horizons ; new species are printed 

 in heavier type.
