Wanklyn, a. — Description of some New Species of Fossil Ferns, from the 



Bournemouth Leaf-bed. Ann. and Mag. Nat. Hist. ser. 4, vol. iii. pp- 



10-12, pi. i. 

 The Ferns are rare in these beds. Four forms are figured, two probably 

 fragments of y/r//(7;//«w and of a species of Cyathea. The others represent two 

 species of Gleicheiiiaccic, for which the author proposes tlic genus Mertensttes, 

 which must, however, be set aside, as it exactly agrees with Debey and Ettings- 

 hausen's genus Didymosoriis, containing three plants from the Cretaceous beds of 

 Aix-la-Chapelle.

form of Calamite. Mem. Lit. and Phil. Soc. Manch. ser. 3, vol. iv. pp. 155- 



183, pi. i.-v. 

 The specimen is elaborately described, and the genus Calamopitus is established 

 for those forms of Calamite "in which the woody elements consist of reticulated 

 vessels associated with medullary rays, and having verticils of medullary radii near 

 tlie nodes."

 The author is satisfied that the stem had an exogenous growth, with crypto- 

 gamous fruit. 

 On a New Form of Calamitian Strobihis : Abstract. Proc 



Lit. and Phil. Soc. Manch. vol. ix. pp. 7-9. 

 This fruit is supposed to belong to the author's genus Cala9?iopitus, and differs 

 from the Volkmantiia described in Joum. Bot. vol. v. p. 349, in the sporangia being 

 supported on a sporangiophore rising from the surface of the scales. 

 . On the Structure and Affinities of some Exogenous Stems 



from the Coal-measures. Month. Micr. Joum. vol. i. pp. 66-72, pi. xx. 

 A new genus (Dictyoxylon) is estabhshed for the exogenous stems of the coal- 

 measures, whose tissues are composed of reticulated fibres.
