In many of the polypites the anterior 

 portion of the body is much swollen and 

 destitute of tentacles, a change which is

I have not had the opportunity of ex-

 The foregoing description is founded on 

 numerous specimens, well preserved in

ZOOPHYTE bushy ; STEM slender, slightly and irregularly 

 annulated throughout, much branched ; polypary delicate 

 and light-coloured; BRANCHES erect, long, closely set, 

 much and irregularly ramified; POLYPITES somewhat 

 swollen beloiv, tapering above, with about 20 tentacula, 

 which are rather long and furnished with small capitula, 

 a verticil of five immediately below the mouth, and the 

 rest scattered. 



GONOPHORES densely clustered, chiefly about the lower part 

 of the body, sessile. 



Height from an inch to an inch and a half. 



THIS species forms dense, clustered, bushy masses on 

 Fucus ; it is of very delicate habit. The polypary, which 

 is extremely thin and transparent, is more or less ringed 

 throughout, but the annulations are neither regular nor 

 strongly marked. The branches grow erect, and attain a
