The Body is rounded with a median ventral furrow, and depressed 
( ? from pressure). The mantle-opening is slightly less than half 
the circumference, and terminates midway between the siphon and 
the eye, and a little behind the latter. The siphon is comparatively 
short and conical, and extends one-third the distance to the umbrella- 
margin. 
The Head is comparatively broad, almost as broad as the body, 
and the eyes appear to have been prominent. 
The Arms are unequal, the ventral considerably shorter than the 
dorsal and dorso-lateral, on an average six times as long as the body, 
stout and tapering very rapidly towards the ends. The umbrella 
reaches up one-fifth of the length of the dorsal arms, and is a little 
wider between the lateral and a little narrower between the ventral 
arms. The suckers are not closely packed, and not enlarged on 
the dorsal arms, notwithstanding the sex of the specimen. The 
hedocotylised arm is very short, but the modified extremity is long 
and narrow, with parallel sides tapering only at the extremity to a 
blunt point ; a narrow fillet runs between the two marginal ridges. 
The Surface of the body is sprinkled dorsally with minute 
hemispherical warts, which become smaller and gradually disappear 
on the sides and lower surface ; they are also found on the dorsal 
surface of the head and of the umbrella. Above each pupil stands 
a small cirrus, immediately behind which is a larger one. 
The Colour is a dull red on the dorsal surface, lighter and brighter 
below, sprinkled with dull reddish-brown dots. 
Habitat. — The Hyalonema- ground south of Japan, 345 fathoms 
(Station 232). 1 specimen, 6.
