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. The Jin occupies a little more than half the length 
of the body, is rhomboidal, not quite so broad as long, and broadest 
anteriorly to the middle; the lateral angles are rounded. The 
mantle-margin has a slight projection 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 distinctly keeled externally ; the fourth are inter- 
mediate 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 arms 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 
papillae. The buccal membrane has the usual seven angles pro- 
duced into long lappets, each of which bears about eight suckers in 
two rows ; the outer Up is moderately thick, the inner 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
