les vaisseaux qui environnent la moelle et, suivant M. Corda, par Tabsence de rayons 

 medullaires. M. Corda ne rapporte a ce genre qu'une seule espece, le Biploxylon 

 cycaddideum, decrite par lui, et trouvee dans le terrain liouiller de Chomle, en Bolicme ; 

 mais je crois que c'est a ce meme genre qui appartient, sans aucun doute, X Anabathra 

 pulcherrima de Witliam (' Int. Struct, of Foss. Veg.,' p. 40, pi. 8), et je me fonde pour 

 cela sur d'excellentes coupes de ce fossile remarquable, qui m'ont ete adressees par ce 

 savant, et qui montrent que le tissu qui entourne la moelle detruite, mais dont on voit 

 quelque trace, forme un cylindre continu sans direction rayonnante, et compose de 

 vaisseaux rayes disposes comme dans Biploxylon. C'est une seconde espece de ce genre, 

 a moins qu'on ne croie devoir reserver a ce groupe le nom A' Anabathra." 



18. BiNNET^ alludes to the occurrence of spores in the inside of Stiymai'ia, and 

 notices the remarkable crucial sutures on the base of the stems of some SigillaricB. 



19. Dawson" (Roots), in his description of the Coal-measures of South Joggins, 

 Nova Scotia, alludes to Siyillaria having Stiymaria roots. 



20. GoLDENBERG^ describes and figures spherical bodies, some with a triradiate 

 ridge, and others without that character, as the fruit of Siyillaria, Stiymaria, and fossil 

 Selayina. These bodies, according to the author, appear to be attached to the scales of 

 the cones, and not contained in a sporangium ; and in the figures they appear chiefly at 

 the base of the specimen. 



21. BiNNEY* (Roots) gives information as to the origin of the medullary rays, and 

 the nature of the vascular bundles, in the pith of Stiymaria, also as to the structure of 

 its radicles. 



22. BiNNEY^ on Siyillaria and its roots. 



23. BiNNEY^ {Siyillaria and Stiymaria) : — " In the present paper it is my intention to 

 confine myself to the description of three specimens of fossil plants which would gene- 

 rally have been designated Lepidodendron in England and Sayevaria on the Continent. 



" No. 1. — The specimen illustrated in pi. iv consists of a cylindrical stem i^ths of 

 an inch in diameter, nearly enveloped in its stony matrix, and only showing its external 

 characters on one side. These consist of rhomboidal scars of an elongated and some- 

 what irregular form, arranged in quincuncial order, but not so perfectly as seen in most 

 species of Lepidodendron. In the middle of each scar there is an oval depression, from 

 which rises a rounded prominence, where the leaf was attached. The scars resemble 

 those of Lepidodendron selayinoides, figured by Messrs. Lindley and Hutton in their 

 ' Fossil Flora,' vol. i, fig, 12, but the depression in the scar on their specimen is not so 

 marked as in mine.
