ii. CAMPYLONEM IDA, Hincks. 



Tentacles not forming a perfect circle, two of the number 

 being always everted. 



THROUGHOUT this group the polypide is of the simplest 

 structure and of very delicate habit, and in all cases it 

 exhibits the curious arrangement of the tentacles which 

 has suggested the name. Two of the number are uni- 

 versally bent outwards towards the side, so that the 

 tentacular wreath does not form a perfect circle ; the 

 remaining six stand erect, in the usual way. I believe 

 that the two everted tentacles are always placed on the 

 same side as the anal opening. The number of tentacles 

 is constantly eight ; a gizzard is always wanting. 



The remarkable modification of the tentacular wreath 

 must be regarded as an important character, and as afford- 

 ing a very sure indication of natural affinity.
