116 TRUNCI. 



40962. Joura. Bot. vol. v. 1867, pi. Ivii. fig. 9. One of the 

 two specimens is the type of Carruthers' species, Cycadeostrobus 

 d'-yam. In the better specimen, as shown in the figure, 

 the pyritized cone has been more or less compressed ; at 

 the base there is a central depression or scar of attachment of 

 a peduncle. The surface view of the scales suggests a wearing 

 down of their distal ends. The second example is less perfect 

 than the type specimen. Brook Point. Lady Hastings Coll. 



V. 2543. Two specimens, very friable. Cf. Carruthers' figure 

 of Cycadfiostrobus ovatus, Carr. Possibly Cycadeostrobus truncatus, 

 Carr., 1 might also be included as a synonym of the present 

 species. Brook. Presented by A. Dendy, Exq., 1888. 



V. 63. Imperfect pyritized specimens. These and V. 2543 are 

 somewhat larger than the cone represented by Carruthers in Journ. 

 Bot. vol. v. pi. Ivii. fig. 9 ; but they are probably examples of the 

 same species. Brook. Purchased 1882. 



V. 2853. Portion of a flattened cone ; apparently the same as 

 40962. Sussex. Heckles Coll. 



V. 385. Very imperfect pyritized specimens. Brook. 



Presented by C. Westendarp, Esq., 1884.

In the introductory remarks 3 on cycadean fronds it was 

 suggested that the use of some more general term than that of 

 Cycadacea, might prove advantageous in dealing with the remains 

 of extinct cy cad-like leaves. The chief reason for such a proposal 

 is to be found in the character of the floral structures of the 

 genus, for which Carruthers instituted the name of Bcnnettites. 

 This plant, as we have already shown, cannot well be included 

 in the class Cycadacea as at present defined for recent species ;
