Tlie nunil)er of species yielded by each locality is as follows : 



Ötake 196 of which 164 or 83.6^ are found in one or more of the other localities. 



Shisui 81 of which 74 or 91.0^ are found in one or more of the other localities. 



Kamenari 56 of which 52 or 93.0^ are found in one or more of the other localities. 



Kioroshi 49 of which 44 or 90.0^ are found in one or more of the other localities. 



Teo-a 117 of which 99 or 84.6^ are found in one or more of the other localities. 



Shito 218 of which 192 or 88.0^ are found in one or more of the other localities. 



From this it is quite clear that the faunae of all the localities 

 are very similar to one another. And this is what might be 

 expected from the position of the shell-layer in which they were 

 collected and which, seen from a geological point of view, can not 

 be considered as representing more than a single horizon. And 

 this horizon I propose to call Manzahian from the railway station 

 of Manzaki'^ close to which the fossil locahty of Otake lies.
