THE E deep- -sea Anthozoa obtained last season were numerous 
and interesting, but there were among them only a few entirely 
hew forms, fox: most of them had been dredged by the Alba- 
- tross in 1883, or by the Blake in 1880. The most remarkable 
ew species, of which one imperfect specimen had been taken 
in 1883, but not described, represents a new genus of Penna- 
talide, I have named this Benthoptillum sertum.* This, which 
was taken j in 991 to 1073 fathoms, is a remarkable exception
