and Halonial tubercles in L. Harcourtii really belong to 

 another species L. Hickii sp. nov. 



L. Hickii is described, and shewn to have the ordinary 

 Lepidodendroid type of internal structure. 



It is shewn to be a Lepidodendron, and compared 

 with the specimen of Lepidodendron ophiurus described by 

 Carruthers as Halonia gracilis. 



Its " Halonial " branches are not considered as 

 fructigerous, and the accuracy of the application of the 

 term Halonial is challenged. 



The new species is contrasted with L. Harcourtii, 

 Witham, and compared with L. vasculare, Binney. 



I have to express my thanks to Professors Seward 

 and Weiss for encouragement and advice, to Mr. Kidston 

 for information on several subjects, to Miss K. H. Coward 

 for making drawings for some of the illustrations, and 

 to Dr. A. S. Woodward for many kindnesses at the 

 Natural History Museum. 



Lepidodendron Hickii is to be regarded as founded on 

 the following sections.
