scarcely half their normal size on the left side, aud still smaller on the 
right side. The left tentacular arm is only 24 mm 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 dentic- 
ulated. The right tentacular arm is less than half as long (12 mni ) 
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 mm long; the 
left one 15 mra long ; both are provided with very small but otherwise 
normal suckers. 
In another specimen from Vineyard Sound, a female, with the 
mantle about 150 mm 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 curva- 
ture; 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 
capsules (cut 3), 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 
inches in diameter, containing hundreds of the capsules, which are 
mostly from two to three inches long and tilled with numerous eggs, 
the number varying from 20, or less, up to about 200. The trans- 
parent eggs are arranged, in the well-formed capsules, in six or more 
rows and are so closely crowded that they touch each other and 
often take polygonal forms, especially when preserved. 
How many of these capsules are deposited by one female is very 
uncertain. Probably several females are concerned in the formation 
of the larger clusters. The eggs are mostly laid in June and July, 
but many are laid in August, and some even in September. I>y the
