This species is closely allied to the two following forms which occur 

 on the same host, all of which have an appearance, unusual in members 

 of this genus, from the contrasting suifusions of the bases of the 

 appendages and of the cells which bear them, giving the margins a 

 transversely banded appearance. There are not more than one or 

 two antheridia distinguishable in any of the eight individuals examined, 

 and the hyaline portion of the appendages is inconspicuous from its 

 appressed habit, and tendency to become disorganized. 



Rickia nigrofimbriata nov. sp. 



Asymmetrical, straight. Receptacle triseriate, the basal cell rela- 

 tively large, short, broad, subtriangular, becoming wholly suffused 

 with brown: anterior series consisting of about sixteen cells which are 

 subequal, except the five terminal ones which bear no appendages; 

 the four subterminal more flattened, and obliquely superposed; the 

 terminal forming a short, stout, rounded, free, finger-like prominence 

 extending above the apex of the perithecium; the remaining cells, 

 except the basal, cutting off a relatively large cell distally and ex- 

 ternally; all of which, like the lower half of the small, stout, abruptly 

 upcurved appendages, are nearly or quite opaque, gi\ing the otherwise 

 hyaline body a fringed appearance: posterior series similar to the 

 anterior, consisting of eleven or twelve cells, the basal and distal 

 without appendages: median series consisting of eight or nine suc- 

 cessively smaller cells; the lowest slightly intruded between the third 

 pair of marginal cells; the free base of the primary appendage placed 

 betAveen the two terminal cells of the posterior and median series, 

 its basal cell short and broad, its distal nearly twice as long, and nar- 

 rower; the appendage short, erect, normal. Perithecium relatively 

 long and narrow; its posterior margin somewhat more than one 

 half free, symmetrically somewhat convex; the tip not clearly dis- 

 tinguished, partly free above the anterior series; the apex bluntly
