1 IS TUBULIPORIDJE. 



central disk and the basal portion of the lobes the cells 

 are arranged as in the normal T. flabellaris ; on the en- 

 larged heads they are disposed somewhat radiately. This 

 curious variety, deprived of its terminal expansions, bears 

 a striking resemblance to a Sun-Star (Solaster). In form 

 and general appearance it is quite unlike the ordinary 

 T. flabellaris ; yet such is the tendency to irregularities 

 of growth and habit in this section of the Cyclostomata 

 that I do not venture to regard it as more than a very 

 singular illustration of this characteristic.
