202 AXOMOZAMITES. 



V. 3688. PI. II. Fig. 7 (slightly enlarged). 



A side-view of a disc similar to V. 3284, shown in surface-view 

 in Fig. 8, PI. III. The sides of the central dome-shaped portion 

 are marked by a series of rather prominent ridges, between which 

 occur pairs of slight depressions, indicated in the drawing by 

 black dots representing small patches of carbonaceous matter. 



Depth of the disc from the summit of the dome - shaped 

 projecting portion to the end of the bract = 4 cm. 



39,334. Text-fig. 35. 



The surface-view of the base of a flower; a small raised boss 

 occupies the centre, which is surrounded by a slightly depressed 

 area succeeded by a raised rim ; beyond this the surface is covered 

 with a fine reticulum, of which the meshes or polygonal areas 

 become more elongated towards the periphery, where they pass 

 into radiating ridges. Cf. Williamsonia Carruthersi, Sew. 1 



39,094. Part of a disc with bracts ; the latter shows very 

 clearly the irregular striations similar to those which characterize 

 the bracts in Williamsonia gig as, and due, no doubt, to the presence 

 of strands of hypodermal strengthening tissue. 



39,296. Two discs and fifteen marginal bracts. Cf. IVilliamsonia 

 gigas (PI. VIII. Fig. 1). Portions of fronds occur on the same 

 piece of rock. 



Genus ANOMOZAMITES, Schimper. 

 [Trait, pal. veg. vol. ii. p. 140, 1870.] 



The genus Anomommites may be thus defined : 

 Frond comparatively small, linear, or tongue - shaped, usually 

 divided into segments which present a more or less obvious 

 difference in breadth, separate or confluent at the base, attached 

 laterally to the rachis, and never entirely covering the upper face 

 of the frond axis ; the segments bluntly rounded or truncate 

 distally; veins simple and parallel, generally at right angles to- 

 the rachis.
