proximally to them are about half a dozen suckers of different 

 sizes, and beyond them a large number of diminishing ones 

 arranged in four series and occupying nearly half the length 

 of the club. The horny ring in the largest suckers bears 

 about twenty-five square teeth ; in the lateral suckers it bears 

 more than twenty close-set bluntly pointed teeth, and in the 

 distal ones about the same number of similar character. 



The Surface is smooth. 



The Colour is pale, with purplish chromatophores. 



The Gladius is of quite typical form, expanded behind, and 

 about six times as long as broad ; the narrow anterior extre- 

 mity occupies less than one third of the total length.

Sepia esculenta, n. sp. 



Tl^ Body is broad, stout, and semielliptical posteriorly. 

 The Jins are about one fourth of the body in breadth and 

 commence within 6 millim. of the anterior margin, and end 

 within 5 millim. of each other ; the mantle-margin is pro- 

 duced far over the head dorsally, and evenly truncated below. 

 The siphon just reaches the gap between the ventral arms. 



The Head is broad and the eyes laterally prominent. 



The Arms are subequal, the order of length being 4, 1, 2, 3, 

 and nearly half as long as the body ; they are all more or less 

 compressed, especially the ventral ones ; they have a distinct 

 web along the outer margin, and a rather broad membrane, 

 runs up either side of the sucker-bearing face. The suckers 

 are in four series throughout, not very obliquely set ; they 

 are large and spheroidal, and have meridional markings on 

 the outer surface ; the horny ring is smooth and surrounded 

 by a narrow papillate area. In the hectocotylized arm of the 

 male the first four rows of suckers are normal, then come' two 

 rows of gradually diminishing suckers, succeeded by four 

 rows of minute ones, after which they regain their normal 

 dimensions. The umhrella is narrow, widest between the 

 second and third arms, where it reaches up to the fifth row 

 of suckers. The huccal membrane has the usual seven points 

 in the male ; in the female the two ventral ones are rounded 

 off; the spermatic cushion is exceedingly well developed, and 

 has four deep transverse grooves. The outer Up is thin and 

 longitudinally corrugated ; the imier lip is thick and bears 

 numerous very long papillse.
