and those of the ventral row are again a little larger than those of the dorsal in 
the middle of the arm; the first left arm is a very little shorter than its fellow 
and decidedly thicker; the suckers are first in two and afterwards in four 
rows, and extend about halfway up the arm, where they 
. are succeeded by a number of stout papillae in two or three 4 
rows (Fig. C) ; these thicken towards the tip, and do not b We 
bear suckers, but each has in its rounded top a slit, much 
resembling a mouth, closed by two lips, one thicker » 
than the other ; they diminish rapidly towards the tip of O

three suckers of the dorsal series and four or five in the 
ventral much enlarged, though not to 80 great an extent as 
in the third pair. The web between the third and fourth 
arms extends up about one- fourth of their length; it is 
very small between the other pairs of arms and absent 
between the ventral pair.

The Color is yellowish gray, with very conspicuous chromatophores, espe-

of transversely elongated oval chromatophores up the outer surface, as figured 
by Grant, and a small round one on the pediele of each sucker of the two outer 
rows. There is also a row of transversely placed oval ones on the outer side 
of the tentacular stem.
