1 44 BENNETTITES. 



can be no doubt as to the original of Mantell's figure; the fact 

 of its being figured is recorded on the label, but there is no word 

 "Brook" written on it. No doubt Solms is referring to some 

 other specimen ; in another place the same author speaks of 

 Mantell's figure as a very good representation of a specimen in 

 the Geological Department. 



38361 and 38362. Solms l refers to this specimen (cut into two 

 pieces, bearing the above registered numbers) as being without 

 fructification. On the smaller piece there appears to be inflores- 

 cences shown in transverse and longitudinal section. The label on 

 one piece bears the name Clathraria Lyellii. Possibly this specimen 

 should be referred to Bennettites Saxlyanus. 



V. 3232. Another waterworn specimen cut into three pieces, 

 one transverse slice and two larger portions. It would seem 

 impossible to definitely refer this imperfect example to one or 

 other species of Bennettites.

V. 3177. The chief interest of this specimen is in the numerous 

 casts of inflorescences which occur on the stem. The surface 

 features cannot be accurately made out ; the portions shown in 

 PL XY. Fig. 1 exhibit the conical cavities originally occupied 

 by the fertile axes, and the impressions of petioles and ramental 

 tissue. The whole surface presents a somewhat waterworn 

 appearance, and instead of showing a surface view of the petiole 

 bases in the form of rhoinboidal sections, it has the form of 

 a worn-down surface with an oblique view of petiole casts and 

 ramental tissue. 



In longitudinal section the fertile axes have the form of cavities 

 narrowed towards the distal end ; these cavities were no doubt 

 originally occupied by the fleshy terminations of inflorescences. 

 The wall of such a cavity (PL XV. Fig. 3) shows clearly preserved
