STREPHENTERUS CLAVIGER (tentacular appendages of), Norman, Ann. N. H. 

 ser. 3, vii. (1861) pi. ix. figs. 1-3. 



Body elongate-ovate ; tentacles 12-18 ; 

 peduncle of great length, the lower 

 extremity " pointed like the nib of a 

 pen ;" no pedal gland or other special 

 organ of attachment ; buds never ex- 

 ceeding two. 



THE long peduncle of this species is 

 highly contractile, and its movements 

 are very energetic ; besides bending to 

 one side and then straightening itself, 

 it is occasionally twisted into a spiral. 

 In the buds the pedal gland is very dis- 

 tinctly visible ; but it subsequently dis- 

 appears altogether. According to Vogt, 

 it is absorbed after furnishing the se- 

 cretion by which the animal is perma- 

 nently fixed. 



In both this and the preceding 

 species, the oblique position of the 

 tentacular crown on the ventral side 

 of the body is a very marked charac- 

 teristic.
