This, and the preceding, may prove to be one species ; it is distinguished 

 from F. agglutinans, principally by the much larger number of tubes on 

 its disk, and by the larger size of its tube. 



Subgenus Arytene.

Dr. Gray considers F. Recluziana a variety of the following species, 

 F. t u b e r c u 1 at a ; the tubuli in the latter are, however, very regular, and but 

 little spread out, showing a marked contrast to the rather irregular fringe of 

 this pecies. 



Mr. Reeve quotes F. Recluziana as a synonym of F. incrassata, in 

 which he is incorrect, for the former having a prior place and figure in Chenu's 

 Monograph, must, of course, be retained as the name of the species.
