MADOKA SASAKI : 



Small as these differences may seem, I consider them sufficiently im- 

 portant to be used for the specific distinction. The characters in 

 question were found to be constant, and although a large series of 

 specimens have been examined, no intermediate forms between the 

 two species have as yet been discovered. 



Genus Sepiola Leach 1817. 



3. [Sepiola japonica Tilesius et d'Orbigny, 1839.] 



Sepiola japonica, d'Orbigny (from Tilesus MS.) in d'Orb. et 

 Férussac 1839, p. 234 (Japan). — d'Orbigny 1845, p. 251. 

 Sepiola? japonica. Gray 1849, p. 93. — Tryon 1879, p. 157. 

 This is at best a doubtful species. 



Genus Inioteuthis Verrill 1881. 

 4. Inioteuthis inioteuthis (Naef 191 2). 



Local name : Chôchin-ika (Himi, Etchû Prov.), Dango-ika 

 (Namerikawa, Etchû Prov.).

Sepiola inioteuthis, Naef 19 12, p. 268. 



This species which was first taken by Verrill to be identical with 

 the preceding doubtful Sepiola japoiiica, though assigning it to his 

 Inioteuthis, was later made by Naef into a new species under the name 

 of Sepiola inioteuthis. While I regard it proper to accept Verrill's
