characters already pointed out, it differs in the form of the papillae and the greater length of 

 the dorsal tentacles. 



Two specimens were taken by the dredge in Torbay, in the months of May and June, 

 1845. They were rather inactive, and made very little progress when swimming. The 

 foot seems well adapted for grasping corallines^ but scarcely fitted for moving on a plain 

 surface. 



The spawn is white and deposited in a waved thread, forming a spiral of two or 

 three turns.
