96 MR ROBERT KIDSTON ON THE 



Remarks. — This seed I originally identified as a small specimen of Rhabdocarpus 

 multistriatus, Presl., sp., but now believe it to be the Rhabdocarpus sulcatus, Presl., sp. 

 (which must not, however, be mistaken with the Carpolithes sulcat(a)us, L. and H., 

 which is an essentially distinct species).* 



I have figured, from the Radstock Coal Field, a seed which appears to be the true 

 Rhabdocarpus multistriatus, Presl., sp. A comparison of the two figures will show 

 wherein these species differ.t
