Like the two preceding species, this is allied to G. japonica, 

 having the same form of aperture. It differs from G. satsuma 

 chiefly in the fine sculpture, which consists of a dense granula- 

 tion, without spiral incised lines. It differs from G. japonica in 

 sculpture and the reduced umbilicus; from G. ferruginea in the 

 pale coloring, small umbilicus and different sculpture.
