Family POLYPODIDJE Hoyle, 1904. 



Genus POLYPUS Schneider, 1784. 



That the genus Polypus attains an especially large development 

 on the coasts of Japan is attested by the formidable list of names 

 which have at one time or another been ascribed to this area, and 

 that despite the fact that, so far as members of this group are con- 

 cerned, the deeper waters off shore are still practically a terra incognita, 

 P. januarii being the only abyssal species thus far reported. How- 

 ever, the true number belonging to the fauna is somewhat obscured 

 by the lack of sufficient diagnosis or other needful information 

 respecting several of the alleged species. The following list is 

 thought to include all the names which occur in the literature: 



Polypus vulgaris Lamarck. P. hongkongensis Hoyle. 



P. granulatus Lamarck ( = rugo- P. dofleini Wiilker. 



sus Bosc.). P. pictus fasciatus Hoyle. 



P. macropus Blsso ( = cuvieri P. areolatus De Haan. 



d'Orbigny). P. ocellatus Gray. 



P. kagoshimensis Ortmann. P. brocki Ortmann. 



P. globosus Appellof. P. fang-siao d'Orbigny. 1 



P. pusillus Gould. P. sinensis d'Orbigny. 1 



P. j'anuarii Steenstrup. P. membranaceus Quoy and Gai- 



mard. 



Polypus vulgaris (Lamarck, 1799). 



Octopus vulgaris Lamarck, 1799, p. 18 (fide Jatta). 



Octopus octopodia Tryon, 1879, p. 113, pi. 23, figs. 3, 4 (after d'Orbigny); 



pi. 24, figs. 5, 6. (after d'Orbigny); pi. 24, fig. 7 (after Jeffreys). 

 Octopus vulgaris Appellof, 1886, p. 7. 

 Octopus vulgaris Ortmann, 1888, p. 642. 

 Polypus vulgaris Wiilker, 1910, p. 5. 



As I have had no European specimens of P. vulgaris available 

 for comparison, I cannot feel personally certain that the following 

 specimens are correctly referred to this species, but I think little 

 doubt exists that they are conspecific with the form so identified 



to 



without anj _ . _. , ... 



can never have any standing. Appellof has suggested that 0. Fang-siao belongs 

 to the synonymy of 0. ocellatus. Tryon refers 0. sinensis without hesitation 

 to 0. membranaceus, Hoyle somewhat dubiously unites it with 0. areolatus , 

 while Appellof places it with a query under O. vulgaris.
