brown mottled with buff. The shells of both are, however, alike, 
and that of the male was compared with the shell of a type male 
in the British Museum and found to be exactly similar. This shell 
measures about 58 mm. in length by 25 mm. in breadth, and has 
an index of about 30; the spine is broken. Both specimens ex- 
hibit irregular teeth or notches on the distal surface of some of 
the arm rings, while other rings are quite smooth. M *4°* pos- 
sesses from 8-10 teeth, and M **°* 11-18. The hectocotylized arm 
of the latter specimen has five normal rows of suckers proximally, 
followed by seven rows of modified suckers.

These are “‘ conspicuously striped with broad dark bands on 
the upper surface of the mantle, head and arms” as described by 
Goodrich. The form of the hectocotylus and the arrangement of 
the teeth on the arm and tentacular sucker rings agrees with the 
type except for an interesting deviation as regards the large tenta- 
cular rings of specimen M “*4**, Goodrich has pointed out that 
the largest tentacular rings in this species are smooth and the 
others are denticulate, aud that this is one of the characters 
separating it from the nearly allied species S. rvouxii, d’Orb., which 
has all the tentacular rings denticulate. Specimen M *2°°, which 
is the smallest of the above, has the largest tentacular suckers of 
2 mm. in diameter with denticulate rings like the small suckers.
