Sy^temutic knowledge of lAtJiothaiiiniuii i.s not as yet in a sati.s- 

 factory condition. Tlii« Ibsi^il wns lornierly relegated to a con\\ under

 L'pcmhy Linné, Lamarck, Laniauroux, Cuvier. Ellis, Solannder, Heu.ss, 

 etc., among Avhom the last author gave the name of Xidlipora nuiiosissi- 

 vta to the irregularly ramified, coral-like calcareous lorm, occurring in 

 tlie limestone of Leitha near \ ienna. Kiitzing proposed the name 

 of Spoiiditt'!^ stalactica for the tinv stalactic form of it. Ilaidinger' 

 offered tlie explanation that X raiiiu-sissiiita is a sedimentary body. In 

 185<S, Franz Lnger proved for the first time that A', raiiiusissiiiia is 

 neither an animal nor a stalactic body, but a plant. In LS72, C. \\ . 

 Giimbel wrote an excellent paper, entitled Die m-ijcnannUn Xiilliporcii, 

 etc., in the above-quoted AbliandluH(jcn, in which he end.odies sys- 

 tematic descriptions of the fossil species and announces that ihey are 

 to be distinguished from one another only by tlie relative dimensions 

 of the tissue-cells. Solms-Laubach, on the contrary, said as 

 foll<j\vs : "Jt is extremelx" difticult to distinguish the species in 

 the li\ing re[)resentatives ol rliis group, and it may l)e re;ulih' 

 conceived that the difiiculty of dealing with the fos.'sil forms is 

 still greatei'. We shall do well to follow Unger in this matter, 

 and to put them all t(3gether as Litliolhainniiim rdiiiosissiiiiHiii.'' "
