for a distance equal to half its length down the stem : there 

 are from six to eight rows of very minute suckers^ subequal, 

 and with smooth horny rings. 



The Surface is smooth, except that on one side of the 

 ventral surface are three slightly raised linear ridges, appa- 

 rently due to contraction, and a few minute papillse on the 

 dorsal surface posteriorly. 



The Colour is on the whole pale, yellowish below, purplish 

 above. 



The Shell is hemielliptical in outline anteriorly, tapering 

 to a point behind. The chitinous margin is rather broad, 

 widest about two thirds back ; it covers all except the median 

 third of the dorsal surface^ which is finely rugose where free, 

 and has a slightly elevated median portion and a faint linear 

 ridge in the middle line posteriorly, about 3 millim. long, and 

 terminating 2 millim. from the base of the spine. The ventral 

 surface is but little elevated ; the last locutus occupies more 

 than one third of it, and its posterior boundary is almost 

 semicircular, inflected in the centre. The i7iner cone is eva- 

 nescent ; its limbs are chitinous and form a ventral margin to. 

 the terminal cone. A spine is present, but, as it had been 

 broken off, its length and form cannot be determined. 



Hah. Off the Ki Islands (Station 192), 140 fathoms. One 

 specimen, ^. 



Sepia andreanoides^ n. sp. 



The Body is very long, broadest one third of the way back, 

 pointed and acuminate behind. The fins are narrow, com- 

 mence 3 millim. behind the anterior margin, and terminate 

 5 millim. from the posterior end of the body, and passing 

 on to the dorsal aspect of the body, each approaches within 

 3 millim. of its fellow. The mantle-margin extends well 

 over the head dorsally, and is very slightly emarginate ven- 

 trally. The siphon extends rather further forward than the 

 middle of the eyes, but not up to the space between the 

 ventral arms. 



The Head is decidedly narrower than the body and some- 

 what elongated ; the eyes being distended and laterally pro- 

 minent. 



The Arms are subequal, the order of length being 1, 2, 3, 

 4, or 1, 4, 3, 2 ; they are two fifths the length of the body, 

 elongated, conical (except the fourth pair, which are flattened), 

 and taper to very slender tips. The suckers seem to be nor- 

 mally in four series, but in some cases the arms are so com- 

 pressed that they seem to be in only two, especially at the 

 proximal extremities of the first and second arms ; they are
