One of my specimens is evidently the japonicus type, the 

 surfaces just inside the interbrachial ventral surfaces, as well as 

 the ventral side of the arms being entirely free of granules. The 

 lower margins of both sides of the arms are covered with 

 irregularly polyonal plates, without granules, as shown in Dödee- 

 lein's fig. 2a, PL VII. Dödeelein has not found the canj'i type 

 in Japanese waters. But my two specimens agree well with 

 Ly]vian's description, the granulations of the interbrachial ventral 

 surfaces distinctly extending as far as the base of the oral angles 

 and the outer end of the oral slits. The ventral side of the arms 

 is rather sparsely granulated, the granules being however finer
