Lepidostrohus ? ambiguus^ Binney, ^Carb. Fl. p. 55; pi. xi. f. 1. PaL Soc. This 

 undoubtedly belongs to the genus Bowmanites, which Mr. Binney figures in his 

 next plate. The elaborate drawings and descriptions of Professor Williamson 

 show beyond doubt, what the analogy of allied plants made one expect, that the 

 round bodies are sporangia, and not as Mr. Binney supposes- macrospores ; and 

 the introduction of a large sac inclosing the sporangia in this species makes it 

 doubtful whether they exist in the specimens of cones of Fleniingites, which he 

 figures as seven species of Lepidostrobus. Besides, the preparations of Professor 

 Huxley have conclusively established my interpretation of the " macrospores," 

 for he had detected around these bodies immense quantities of microspores 

 composed, as in E. Brown's Triplosporites, of three sporules, and in the interior 

 of some of the " macrospores " themselves he had observed and has shown to me 

 several microspores yet remaining. Carboniferous. Arran.

 perhaps the same species as that of which Binney figiu'es the external form.

Arthrostigma gracile, Daws. Foss. PL Canada, p. 41 ; pi. xiii. Devonian. Gaspe. 



This is a species of that group of plants to which Haughton gave the name 



Cyclostigma. It has no points of correspondence with Calamites; the leaves 



are spirally arranged in all the specimens figm-ed, and not in whorls as in Dr. 



Dawson's restoration.
