chamber, a simple basal favella. Colour a livid purplish-red. In drying the 

 frond adheres pretty closely to paper. 



At Plate LVII. {Chylocladia CUftoui), I have figured a species 

 nearly related to the present, but diflPermg m colour and sub- 

 stance, and especially in the connection of the internodes. In 

 C. CUfto^ii, the constriction at the node, though considerable, is 

 not greater than what is found in C. articulata ; here every in- 

 ternode is separated by a slender, filiform pedicel. 



C. Muelleri appears to be rare, very few specimens having yet 

 been obtained from either of the two locahties in which it is 

 found. 



Pig. 1. Chylocladia Muelleri, — the natural size. 2. Some internode' 

 bearing cystocarps. 3. Section of an interuode and cystocarp. 4. Part o 

 the periphery of the same, and the cystocarp. 5. Spores variously mag- 

 nified.
