Loligo eduliSj n. sp. 



The Body is moderately stout, being about three times as 

 long as broad, cylindrical in its anterior third, and tapering 

 gradually to a bluntish point. T\iQ,fin occupies a little more 

 than half the length of the body, rhomboidal, not quite so 

 broad as long, and broadest anteriorly to the middle; the lateral 

 angles are rounded. The mantle-margin has a slight pro- 

 jection in the median dorsal line and a broad shallow sinuate 

 excavation ventrally. The siphon is of moderate length and 

 bluntly pointed. 



The Head is small, with prominent rounded eyes^ and bears 

 the usual auricular crest and preocular pore. 



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

 and about half as long as the body. The first are very 

 slender and bear a distinct keel on the dorsal aspect ; the 

 second are thicker and triangular, and have a broad keel 

 almost expanding into a web on the lateral aspect ; the third 

 are the stoutest, flattened from above downwards, and di- 

 stinctly keeled externally ; the fourth are intermediate between 

 the third and second, triangular, and with a broadish web 

 extending the whole way up the dorso-lateral aspect. They 

 all have a web up each side of the inner face. The suckers 

 are in two series, very oblique, and with slender conical 

 peduncles, their size varying with that of the arras on which 

 they are situated ; the horny ring bears eight long square-cut 

 teeth on its distal margin. The hectocotylus is developed as 

 usual on the left ventral arm, which bears proximally ten 

 rows of suckers, then a minute sucker with an exaggerated 

 peduncle, and beyond this two series of long conical papillas. 

 The buccal membrane has the usual seven angles produced 

 into long lappets, each of which bears about eight suckers in 

 two rows ; the outer lip is moderately thick ; the inner lip 

 much thicker and marked with deep radial grooves. 



The Tentacles are about as long as the body, with flattened 

 stems ; about one third their length is occupied by the club^ 

 which is only slightly expanded, and has a protective mem- 

 brane on either side, but a dorsal web is present only at the 

 extremity. The central suckers are about sixteen in number 

 and about one third larger than the laterals ; the proximal are 

 about ten ; the distal are closely packed in four series. The 

 horny rings of the largest are provided with about twenty
