[141] CEPHALOPODS OF NORTHEASTERN COAST OF AMERICA. 
afterwards reproduced. In such examples new suckers of various sizes, 
from those that are very minute up to those that are but little smaller 
than the normal ones, can often be found scattered among the latter on 
the same individual. It seems to me possible that some of the speci- 
~ mens having the suckers on the tentacular arms unusually small may 
have reproduced all those suckers, or, still more likely, the entire arm. 
I have seen specimens of this species, and also of O. illecebrosus, which, 
after having lost the tips, or even the distal half of one or more of the 
sessile arms, have more or less completely reproduced the lost parts.* 
In such cases the restored portion is often more slender and has smaller 
suckers than the normal arms, and where the old part joins the new 
there is often an abrupt change in size. Probably this difference would 
wholly disappear after a longer time. 
An unquestionable and most remarkable example of the reproduction 
of several entire arms occurs in a small specimen taken off Newport, 
kh. 1, August, 1880. ‘This has the mantle 70™" long; dorsal arms, 
22mm; 3d pair of arms, 30™™. The three upper pairs of arms are per- 
fectly normal, but both the tentacular and both the ventral arms have 
evidently been entirely lost and then reproduced from the very base. 
These four arms are now nearly perfect in form, but are scarcely half 
their normal size on the left side, and still smaller on the right side. 
The left tentacular arm is only 24™™ long, and very slender, but it has 
the normal proportion of club, and the suckers, though well formed, 
are diminutive, and those of the two median rows are scarcely larger 
than the lateral ones, and delicately denticulated. The right tentacular 
arm is less than half as long (12™™), being of about the same length as 
the restored ventral one of the same side; it is also very slender, and 
its suckers very minute and soft, in four equal rows. The right ventral 
arm is only 14"™ long; the left one 15™" long; beth are provided with 
very small but otherwise normal suckers. 
In another specimen from Vineyard Sound, a female, with the mantle 
about 150™™ long, one of the tentacular arms had lost its club, but the 
wound had healed and a new club was in process of formation. This 
new club is represented by a small, tapering, acute process, starting out 
obliquely from the stump, and having a sigmoid curvature; its inner 
surface is covered with very minute suckers. The other arms are normal. 
Eggs and young. 
The eggs are contained in many elongated, fusiform, gelatinous cap- 
sules (Plate XXX, fig. 7) which are attached in clusters by one end to 
sea-weeds or some other common support; from the point of attachment 
they radiate in all directions. These clusters are often six or eight incheg 
in diameter, containing hundreds of capsules, which are mostly from two 
_ * Perhaps the Dosidicus Eschrichtii Steenstrup is only an Ommastrephes or Sthenoteuthis , 
which had lost and partially reproduced the tips of all the arms. At any rate, no 
sufficient characters have been given to distinguish it generically.
