A solitary colony, 87 mm. in height, alone represents 
this species originally described by Bale in 1881 under the 
name of Aglaophenia superba. Although the colonies are 
generally simple, specimens have been observed with one 
or two small branches very similar in structure to the 
proximal part of the stem. In the present specimen the 
lower portion of the stem is destitute of hydroclades. A 
branch originates at the side of the stem between two 
hydroclades, and occupies the whole of the space between 
the two. The branch, incomplete, is 11 mm. in length, 
and projects almost at right angles from the side of the 
stem; soon, however, it takes a characteristic upward 
curve, becoming erect, and finally incurved in the distal 
portion. The first four proximal internodes of the branch 
are devoid of hydroclades. The first branch-internode is 
very Short andunarmed. The second is longer, cylindrical, 
and is furnished with a large sarcotheca in the middle. 
Then follow two internodes, each of which carries two 
large sarcothece abreast. The fifth supports a single hydro- 
clade. The remainder are uniform, bearing two alternate 
hydroclades. As Bale’s recent examination of the mode 
of branching in H. superba shows, there is a considerable 
amount of variation in the number of proximal internodes 
bearing sarcothece only.
