Chimœra spilota^ n. sp. 



Two female specimens of Chimœra from off Miyako, Province 

 of Rikuchiu and one male specimen from the Fishery School of 

 Ishinomaki, Province of Rikuzen, show a very close resemblance 

 to Chimœra oivstoni, but differ from this in having no anal 

 notch and in the color. The male specimen, on account of the 

 rather bad state of preservation, is somewhat difficult to identify, 

 but it seems highly probable that it belongs to one and the same 

 species with the two female specimens.
