original type specimens of Verrill, that despite the juvenility of 

 the latter and the admittedly unfavorable preservation of the re- 

 mainder I have thought it well to redescribe the species throughout 

 as carefully and completely as the material would allow. One of the 

 types is likewise figured on Plate VI. Some of the nearly allied species 

 are most puzzlingly close, but it is hoped that the data here given 

 will prove sufficient to prevent its confusion with any of them. It 

 must be confessed, however, that I have been unable to select any 

 characters or combinations of characters which I am certain will 

 suffice to distinguish a series consisting of females alone from any 

 other species of the genus. The males appear to be constantly 

 characterized by the large number of modified suckers on the hecto- 

 cotylized arm, coupled with the fact that the suckers of both the 

 outer rows of the second, third, and fourth arms undergo enlarge- 

 ment, a character exceedingly conspicuous on the second arms at 

 least and in well-preserved material probably on all. 



Good descriptions have already been given by Appellof (1886), 

 Hoyle (1886), Ortmann (1888), and of the anatomy by Wlilker (1910). 

 Yerriirs types are therefore made the basis of the above notes, with 

 the exception of those portions relating to the d% of which he had 

 no specimens. However, his specimens do not differ from the various 

 larger females seen by me in any essential particulars except their 

 dimensions. 



This is the commonest Japanese Sepiolid and has been obtained 

 by so many collectors that it must be a species of considerable 

 abundance. Specimens from Formosa do not seem different in any 

 way, nor have I been able to separately identify the large series of 

 individuals from Hong Kong in the Museum of Comparative Zoology. 

 The latter is also the type locality for Pfeffer's Sepiola bursa, and 

 should not specimens in better preservation prove otherwise, there 

 can be little doubt that this name is a complete synonym of E. morsei.

Body small, compact, short, plump, sepioliform, rounded behind. 

 Mantle attached to the head dorsally by a rather narrow commissure 

 (4.5 mm.) ; free below and produced forward beneath the head, its 

 edge sinuous and slightly emarginate in front, so as to expose the 

 extreme tip of the funnel, otherwise entirely hidden. Fins large, 

 semicordate, the forward lobe extending from the anterior base of
