Stachyptilum, g. n. Small pens without leaves, polyps with cells in 
small rows of four on both sides, and on the dorsal axis of the rachis ; 
cells without stronger spines at their openings, zooids ventral, lateral, and 
dorsal on all free surfaces of the rachis ; all of one kind ; stalk with a 
small zone of papillae at the upper end ; axis pretty strong, round; cal-

lenticular bodies in the stalk, cylindrical corpuscles with three alternating 
ridges on each end in the tentacles of the polyps. S. macleari^ South-east
