duced, from the very base. These four arms are now nearly per~ 
fect 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 s slender, but it has the normal proportion of 
club, and the suckers, tho oug well formed, are diminutive, and 
those of the two median rows are scarcely larger than the lateral 
and delicately denticulated. The right tentacular arm is 
eee ti 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™ jong $ both 
are i Dasa with very small but otherwise normal sucker 
nother specimen from Vineyard Sound, a female, with the 
eatin ae 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 sur face i Is covered with very minute 
suckers. The other arms are normal. 
It seems probable that some of the nominal European species of 
Loligo that have been based on the smaller size of the tentacular 
arms or of the suckers are due to similar instances of regeneration 
of these parts.
