These eighty-one males and fifty-one females taken either by 
shore collecting, or at a few fathoms to four hundred fathoms’ 
depth, chiefly come from the Bay of Bengal region, and south- 
wards to the Andamans and Ceylon. The Persian Gulf and Malay 
Peninsula are also represented. 
All agree in having an oblong body, the breadth of which is 
two-thirds of the mantle-length, except in the case of large females 
(mantle 63-79 mm.), when the breadth is a little more than half the 
length. 
The fins usually begin at a short distance from the mantle- 
margin and are generally formed anteriorly like a roll, and become 
wider posteriorly. The deep water specimens, and many collected 
on shore or at a few fathoms, have very wide fins throughout 
their entire length. 
Head very broad. Umbrella highest laterally, and absent 
between the ventral arms. Arms short and keeled, the fourth 
pair strongly, the first and second very slightly. All with strong 
protective membranes and suckers in four rows. The suckers 
have meridional grooves and distal notches. In male specimens 
the rings of the arm suckers possess eight to fourteen long, 
pointed, closely-placed teeth on the distal margin, the rest of the 
ting being smooth ‘The number of teeth is largest in suckers 
from the centre of an arm, although the proximal suckers may 
equal them in size. A specimen with mantle-length of 36 mm. 
possesses eight teeth on the proximal and distal suckers and ten 
on those from the centre of an arm. 
The female specimens have arm suckers with smooth rings; 
occasionally the horny ring shows indications of ten to eleven 
long, pointed teeth on the distal portion but the margin is 
un-split. In some cases it is notched but not deeply enough to 
form teeth. Wiilker (op. cit., p. 20) refers two females to Sepiella
