A CONTKIBITION TO TlU: GEXl'S FCSULINA. OO 



Its resemblance to the Ku;?sian and l>ritisli species is very 

 striking, and so that they at least show a close relationship to 

 each other, if they are not really identical. 



STACHEIA sp. indet. 



ri. 111., lig. G. 



Fig. (3 shows a peculiar form. In a thin slice of u lime- 

 stone, there is a peculiar form not hitherto met with in the 

 /«sw/ma-limestones of Japan and China. In spite of its great 

 imperfection, however, it seems to me to be a fragmentary 

 specimen of a species of the genus Stacheia. It possesses only 

 7-8 concavo-convex chambers in succession each embracing pre- 

 vious ones except at its peripheral margin. These chambers 

 are subdivided into numerous chamberlets by more or less radial 

 partitions which are almost complete. The chamberlets are 

 ladially elongated and of a varying breadth. The wall and 

 partitions are rather thin, uniform and imperforate ; they appear 

 granular, being preserved in quite a different manner from those 

 of FusuUîia and Lagena which occur in association. 



If its determination as the genus StacJiela is correct, its 

 occurrence in the Korean limestone is of some interest ; for it 

 is by no means a common genus, though not rare in some Car- 

 boniferous limestones of England, ^^ the Carnic Alps,^'^ and Euro- 

 pean Russia.''^ Stacheia Greuinhi Mölle.r'^^ from Persia may
