I identify m}' specimen with the mentioned species after 

 comparing it with the t}'pe of Callith amnion applicitum Harv. 

 in the Trinity College, Dublin. My specimen has been found 

 growing epiphytic on Rhodophyllis capensis Kutz. 



Tetrasporangia are found on the upper side of pinnules, one 

 on each. Sporangium-bearing pinnule is always curved in a

 Frequently, one or two terminal 

 cells are armed with a two-celled 

 minute spine at the upper corner.

the pinnules end in a small and blunt cell, and the sketch of 

 a branch drawn by Harvey on the specimen sheet of the t}'pe 

 shows that character. In my specimen, however, they are 

 never in such manner. Laing observes, I.e., p. 403, that they 

 are acute in the specimens from southern parts of New Zealand 

 and rather obtuse in some from Wellington. The pinnae consist
