Genus CYCADEOIDEA, Buckland. 



[Proc. Geol. Soc. London, vol. i. No. 8, pp. 80-81, 1827.] 

 In accordance with the plan adopted in the description of 

 a Cycadean stem from the Lower Lias of Dorsetshire, I propose 

 to substitute the generic name Cyoadeoidea for Buohlandia in 

 describing the Stonesfleld stem originally figured by Sternberg 

 as Conites Bucklandi.

The type-specimen from Stonesfleld, as figured by Sternberg and 

 by Phillips, is in the Oxford Museum. 



In the diagnosis given by Sternberg the fossil is regarded as 

 a cone, and described as follows : — 



" C. strobile ovato 8 pollices longo, 4 poll, crasso, squamis 

 extus convexis, interna concavis apice subtruncatis vetusisve, axi 

 poUicum fere crassa, squamulis minutis teota."
