The species Sepiola japonica was published by d'Orbigny from a 

 manuscript letter of Tilesius and I cannot find that any specimens 

 were seen by d'Orbigny himself. Gray (1849) copied his diagnosis 

 from d'Orbigny, but expressed some doubt as to its proper reference 

 to Sepiola. Then except for a brief mention in Tryon's " Manual" 

 (1879) we find it otherwise unnoticed for over thirty years. Finally 

 a small collection of squids obtained by Prof. E. S. Morse in the Bay 

 of Tokio was sent by him to Prof. A. E. Verrill, then engaged with 

 his report on " The Cephalopods of the Northeastern Coast. " These 

 specimens furnished the descriptions of two species which were 

 accordingly published in the appendix of this report as a footnote 

 (1881, p. 417), and the genus Inioteuthis was erected to receive them. 

 The form now under consideration was expressly made the
