These agree very closely with Berry’s full description and 
excellent figures. All are characterized by a soft body ; very large 
eves with small openings, stout arms of about two and a half 
times the length of the mantle: a semitransparent umbrella ex- 
tending about equally (slightly less between ventral pair) on all 
the arms for from one-third to nearly one half of their length, and 
continued along their outer margins in membranous expansions ; 
a very small mantle-opening ; and funnel organ of two V-shaped 
pads. 
The tip of the hectocotylized arm is stout and broad, and 
the usual transverse grooves are very obscure in two examples, 
and absent in the third. 
The male specimens show no special enlargement of the 
suckers. The ventral mantle is divided by an incipient groove 
in one specimen only. 
In three examples the funnel is free for the anterior third, or 
less, of its length, in the other it is totally fused to the head. The 
latter specimen is from comparatively shallow water, but the fused 
funnel, when opened, disclosed the same peculiar type of organ 
and the specimen did not appear to differ from the rest in any 
other character. Two examples exhibit clearly two cirri near each 
eye, one being placed above and the other below its dorsal edge. 
The sculpture and colouring are very striking ; each of the numer- 
ous tubercles is surrounded by a dotted circle of minute reddish- 
brown chromatophores, producing a somewhat star-like, or white- 
spotted pattern. The tubercles are sometimes continued on the 
ventral surface, and a few may be observed on the inner dorsal 
surface of the umbrella. In two specimens the dorsal chromato- 
phores are so dense as to present a purple-red tone, and the lower 
surface appear much paler by contrast. 
Three of Berry’s specimens were taken at 257-460 fathoms, 
and the remaining one off the Hawaiian Islands, depth unknown. 
The present examples show that the species does not restrict its 
range to deep water.
