A REVISED LIST OF CORALLINvE. 17 



October number of La Noiiva Notarisia. Madam Weber doul^ts 

 ScHMiTz's view. So do I. The problem is reserved for future 

 until an authentic specimen of Rhodopeltis australis or a fertile 

 exemplar of Litharthron australe has been examined. 



Gen. V. CHEILOSPORUm ZANAKD. emend. 



The genus Cheiloèporum was first instituted by Zanardini 

 to include most of the members of Decatsne's fourth division of 

 Amphiroa. Schmitz^^ extended the generic sense so as to cover 

 the genus Arthroeardia Aresch. The definition of Arthrocardia 

 given by Areschoug is somewhat different from that of the sec- 

 tion Arthrocardia Done. Many of the members of Arthrocardia 

 Aresch. may more legitimately be referred to Amphiroa than to 

 Gheilosporwn. On the contrary, the greater number of species 

 comprised in the section Arthrocardia Dcne. evidently belong to 

 Chellosporum. Hence the genus Gheilosporwn, as conceived in 

 the present paper, comprises both the sections Arthrocardia Done. 

 p.p. and Cheilosporum Dcne. The scope given by me to the 

 genus thus practically agrees with that given by Schmitz, except 

 that some species of Arthrocardia Aresch. have been removed 

 from it. 



The members enumerated under the present genus show 

 certain characters by which they may be easily distinguished 

 from those of the other genera. The most important characteristic 

 lies in the fact that the spores are situated deep in the medullary 

 portion. 



The genus is divided into three sections, viz., Eucheilosporum, 

 Alatocladia and Serraticardia. The Eucheilosporum is a group
