306 AN03IOZAMITES. 



the Scarborough Collection is unusually perfect; the frond has 

 a length of 12cm., and in the middle the leaf is l'9cm. broad; 

 the veins are very indistinctly shown, as is frequently the case 

 in leaves of this species. 



The fronds figured by Nathorst from the Ehastic of Sweden 

 as Anomozamites gracilis 1 appear to be very similar to those of 

 A. Nilssoni, but they are probably not specifically identical. 



39.306. Text-fig. 36. 



This specimen illustrates the striking inequality in the segments ; 

 at the apex the lamina is entire and obtusely pointed ; in the 

 middle and basal portions the lamina is broken up into segments 

 resembling in shape those of Nilssonia compta, but differing in 

 their finer texture as well as in their straighter terminations, 

 in the less curved upper edge, and in the venation. The veins 

 in this specimen are not shown quite accurately in the figure ; 

 if examined closely they are seen to fork fairly often, as in 

 Taniopteris. Labelled by Bean Pterophyllum Nilssoni.

10,313. A leaf showing a more tapered and pointed apex than 

 in 39,306 (Text-fig. 36). Veins hardly visible. 



Gristhorpe Bay. Mantell Coll. 



39.307. Leaf 19cm. long; also a smaller leaf on the same 

 piece of shale. The veins are clearly seen, forking either close 

 to their origin or in different parts of the lamina. 



13,509. Small and fairly well-preserved frond.

52,568. An impression of a single leaf in sandstone, associated 

 with a very good specimen of Ginkgo digitata.
