The status of this species is still very uncertain as it is not quite 

 apparent whether the Octopus ocellatus Gray is the same as the 

 Chinese drawing to which the same name was previously applied 

 by d'Orbigny, or whether the 0. ocellatus Appellof is in turn identical 

 with that of Gray. Tryon refers Gray's species to 0. membranaceus, 

 while Hoyle places 0. ocellatus of both Gray and Appellof in the 

 synonymy of 0. areolatus. However, Appellof's determination has 

 been called in question by Brock. 



Wulker, the most recent writer on the subject, lists the species 

 as P. ocellatus Gray. 



Distribution. — Nagasaki, Hizen (Appellof); China Sea (type 

 locality, Gray).

P. areolatus is a small species with a compact, pyriform body, 

 widest posteriorly, and with a conspicuous ventral furrow. The 

 head is small and weakly differentiated from the body. The dorsal
