good as regards the manner of attachment 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 differing 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) ; cf. also the 

 figure given by Schenk in the Flora der Grenzschichten of Zamitcs 

 distans, Presl, var. longifolia. 1 A specimen from Bayreuth (Keuper) 

 in the Museum Collection (No. 1184) also bears a close resemblance 

 to 39,303.
