CEPHALOPODA .—BERRY. 
19 
Color in alcohol everywhere, excepting the cream-colored suckers, a dull clouded 
slaty grey, only slightly paler below, though quite pale under and around the funnel, 
and with a narrow line of paler tone traceable around the body just below the periphery 
in the position occupied in some species by an integumentary fold, no trace of such a 
fold being here evident. 
Mandibles sharp, but rather thin and fragile ; a good figure difficult to secure from 
the present material (text fig. 12). 
Fig. 12.— M. adelieana.

Radula well developed. Rhachidian teeth with nearly rectangular bases and 
sharply tapering points, so far as I have been able to discover, without lateral cusps.

oblique. Third laterals largest, teeth long, curved, 
and scimitar shaped.
