good as regards the manner of attaoliment and venation of the- 

 leaflets. As shown in the drawing, the pinnae (or leaflets) are- 

 not regularly disposed on the axis, but occur at irregular distances, 

 thus difEering from the more regular arrangement of pinnae in. 

 a Cycadean frond. Each ' pinna ' is narrower at the base and 

 tapers gradually to an acuminate tip ; the veins are numerous- 

 and approximately parallel to the edges of the leaflets. The 

 figured specimen bears a close resemblance to the type-specimen 

 of Lindley & Hutton (in the Manchester Museum) ; of. also the 

 figure given by Schenk in the Flora der Grenzscliiohten of Zamites- 

 distans, Presl, var. longifolia} A specimen from Bayreuth (Keuper) 

 in the Museum Collection (Ifo. 1184) also bears a close resemblance 

 to 39,303.
