Renault, B. lEtudes siir le Sigillaria spinulosa et sur le genre 

 Myelopteris. Mem. Ac. Sci. Paris, pp. 1-23, 1-27 ; 12 plates. 



The structure of the stem of Sigillaria is examined ; and the author 

 concludes that this plant has the structure of a Cycadean stem ; the 

 fruit is needed before its position can be definitely fixed. The internal 

 structure of Myelopteris (Medidlosa, Cotta) is believed to indicate a 

 genus of ferns belonging to the family of Marattiaccce, the type of 

 which has been lost, though it was of great importance during the 

 Carboniferous period. W. C.

Describes the structure of the stems, roots, petioles, and fruits of 

 ferns referred to two species, B. forensis and B. duhius, and considers 

 them intermediate between true ferns and Opliioglossece. W. C.

Completes the Cycadeee with the second volume. The following new 

 species are described and figured : — ClatJiropodium Trigeri, C. Sarla- 

 tense, C. foratum, Fittonia insignis^ P. Rigauxii^ and Cycadeomyelon 

 hettangense. W. C.

Refers the two leaf forms discovered to Coniferae near to GhigJco 



(Salisburia), proposes the names GingJcophyllwn Grasseti and Tricho- 



pitys Tieteromorpha, and compares them with already described forms.

 This fossil would be more accurately named Cedrus Corneti. Com- 

 pares it with the larger Pinites LecTcenhyi, Carr.
