four, short, blunt, spreading horns; The colour is a full, but not a bright 

 red, becoming paler and duller in drying. The suhstmice is thick, between 

 fleshy and cartilaginous, soft, elastic, and shrinking in drying. When dry 

 this plant adheres strongly to paper. 



A fine species, readily known from all others of the genus 

 Callophi/Uis by the form and appendages of the conceptacles, 

 which resemble externally those of a Korea, but differ in in- 

 ternal structure and in the nature of the nucleus. The general 

 habit of the ramification is that of Callopliyllis, and the struc- 

 ture of the frond agrees tolerably with that of typical species ; 

 but the peculiar intermediate network of slender filaments, 

 which ought to separate the large cells of the medullary layer, 

 is not well developed. I do not however know any established 

 genus to which the present plant is so nearly allied as to CaJlo- 

 phi/Uis, and do not consider the characters which separate it 

 from C. coccinea (the commonest Australian type) to be of ge- 

 neric moment. 



It is among the rarer of Victorian Algae ; and as yet I have 

 only seen the few specimens which I collected about Christmas, 

 1854.
