' Zf^c cut opening on one side only of a ramose ;;oar/«///, never adnate

The family lloKNi'.Rin.K, as defined by the Rev. T. llincks, is capable 

 of veiy wide extension, and cn.n bo made to include the Polyporida' 

 ('Brit. Assoc. Rep. Foss. Poly.' 1883), in which I have placed the Fnlji- 

 pora and PhyUopova of the Palieozoic Rocks. It may seem, however, a 

 very ([uestionable proceeding to include so many apparently diversified 

 forms in one family gronp, especially as we have no gradational Hides by 

 which wo can unite the Polypora of the Palajozoic with the well-detined 

 Jloniern of the Tci'tiary Rocks. But, irrespective of the peculiarity, 

 I see no sutlicient reason for keeping the group sei)arate if wo ai'C to 

 accept Mr. Hincks's diagnosis. The same remarks may appl}^ to the
