cones described by Carruthers as different species of Cycadeo - 
strobus x . The latter I ventured to speak of under the generic 
name of Conites 2 , but a comparison of them with more 
recently acquired Wealden cones, leads me to refer them 
all to A raucarites. One of the best specimens figured by 
Carruthers as a cycadean cone is that which he named 
Cycadeostrobus Brunonis 3 ; in a transverse section the seeds are 
clearly seen, and an examination of the specimen tends to 
confirm my view as to its araucarian affinity. It seems quite 
impossible to separate under distinct specific types the several 
pyritized Wealden cones figured in Carruthers’ paper on 
gymnospermous fruits. As a matter of convenience, a 
specific name must be adopted, but in dealing with imperfect 
detached cones it is impossible to arrive at any satisfactory 
conclusions as to different specific forms. Taking Carruthers’ 
species Cycadeosti'obtis elegans , we may briefly define the type 
as follows: — Cones about 6cm. in length, and 4cm. broad; 
central axis stout, marked with spirally arranged diamond- 
shaped areas to which are attached broadly triangular car- 
pellary scales, narrowed towards the base, and slightly winged 
laterally. 
This diagnosis is merely intended as a guide to general 
characteristics, and cannot be accepted as a very precise 
specific definition. The size of the cones varies considerably, 
and it is quite possible that more than one species is included 
in the following list under A. elegans. It may tend to remove 
some of the existing confusion in nomenclature, and to 
express the conclusions arrived at, if we enumerate those 
forms which I propose to include in the genus Araucarites.
