These all agree in the presence of suckers on the buccal 
membrane and in having the tentacle suckers all of small size and 
semi-equal, and armed with acute teeth all round the ring, the 
largest being on the distal half of the circumference. Very promi- 
nent papillae are also apparent in the best-preserved specimens. 
Specimen M **°° possesses what appear to be clubs in process of 
repair at the end of each tentacle stem. They are much narrower 
than the stems and end acutely, and possess a very rudimentary 
fin only visible with a lens; minute pointed papillae, which would 
seem to be the base of suckers (as occasionally fibres of muscle 
project from them), are present on either side of a median line. 
The arm suckers are arranged in four rows and their rings are 
usually armed with many teeth on the distal half of the ring. They 
vary greatly in number and appearance; often two are welded 
together or they may be somewhat widely espaced ; eighteen to 
thirty are present on many rings but those placed on the proxima! 
or distal portions are usually (but by no means invariably) smooth. 
An idea of the variation in dentition is afforded by specimen M ****. 
Fifty-six teeth surround a sucker ring on the middle of the first 
right arm, the distal teeth being the longest ; a sucker on the distal 
half of the third left arm shows a ring with about forty teeth ; 
twenty-one teeth are present on a sucker ring on the distal half of 
the fourth right arm, and are placed on the distal margin, the rest 
of the ring being smooth. All the proximal rings examined in this
