In the meanwhile appeared an important paper by Appellof 

 (Japanska Cephalopoder, Stockholm, 1886), which is significant as 

 being the first time that we find the cephalopods of Japan dealt 

 with as an assembled unit by themselves. In this paper 8 species 

 were added: 



Octopus vulgaris. Loligo bleekeri. 



Octopus globosus n. s. Loligo sumatrensis. 



Octopus macropus. Sepia peterseni n. s. 



Sepioteuthis lessoniana. Sepia ( Metasepid) tullbergi n. s. 



Two years later the publication of a second treatise on the same 

 subject from the pen of Dr. A. E. Ortmann (Japanische Cephalo- 

 poden, Zool. Jahrb., 1888) marked another notable increase in our 

 knowledge. Thirty-six species referable to 10 genera are accredited 

 to our area, of which the following are first recorded: 



Tremoctopus doderleini n. s. Loligo tetradynamia n. s. 



( = Ocythoe tuberculata) Loligo chinensis. 



Octopus kagoshimensis n. s. Loligo aspera n. s. 



Octopus pusillus. Sepia hoylei n. s. 



Microteuthis paradoxa n. s. Sepia torosa n. s. 



( =Idiosepius). Sepia tokioensis n. s. 



During the next twenty years succeeded another period of only 

 occasional short papers and desultory notes, the most important 

 of which are those of Pilsbry (Sepia hercules, 1894), Ijima and 

 Ikeda (Opisthoteuthis depressa 1895, Amphitretus pelagicus and 

 Alloposus pacificus 1902), Mitsukuri and Ikeda (1898), Joubin 

 (1897, 1898), Pfeffer (1900), Nishikawa (1906), Meyer (1906), and 

 Chun (1908, 1910). 



Very recently Wiilker (1910) has published a third survey of the 

 Japanese members of the group, based upon a portion of the valuable 

 material brought to Germany by Dr. Doflein. In this work, notable 

 for its numerous interesting data and the able manner in which they 

 are presented, Japan is accredited with no less than 24 genera com- 

 prising an even 60 species (3 of them doubtful). The following are 

 additions to the fauna: 



Tremoctopus violaceus. Sepia elliptica. 



Polypus dofleini n. s. Sepia lorigera n. s. 



Polypus pictus fasciatus. Sepia misakiensis n. s. 



Sepia aculeata. Sepia appellofi n. s. 



Symplectoteuthis oualaniensis. 



In the present catalogue the recognized number is increased to 

 67 species (4 considered doubtful), falling under 29 genera, with
