A young specimen from station 289 is 22.5 cm. long, very slender, with a length 

 mm. without calyces, and 15 mm. with calyces. The calyces are lateral and regularly 

 alternate, averaging about 2.3 mm. apart. In form they are low cones with rounded summits 

 which are directed outward. The spicules are as in the specimen described above. Another 

 specimen trom the same station lias lateral calyces which appear much more prominent on 

 account of the partial expansion of the polyps. It also shows a faint median impressed line. 

 A specimen taken from station 208, depth [886 meters agrees quite well with young speci- 

 mens from station 260 (90 meters) and 204 (94 metei 



lt is altogether likely that some of the so-called species of this genus that have been 

 described a lly distinct and are listed on page 24 are based on young specimens 



of this form.
