It resembles Cedrus Lennieri, ' Sap. Veg. foss. de la Craie inferieure 

 des Environs du Havre,' Mem. de la Soc. Geol. de Normandie, 1877, 

 but is not apparently the same species. 



Pinites cylindroides, sp. nov., Lower Greensand, Potton. 



This is an almost perfectly cylindrical specimen, being very 

 slightly thickened towards the base, 7 centimetres in length and 

 22 millim. in diameter, composed of about 96 scales, arranged in 

 12 rows from left to right, and eight rows from right to left, the 

 arrangement thus being --fe. The scales are short and at right angles 

 to the axis, with a smooth flat half-moon-shaped apophysis or scale- 

 head, now gaping, but evidently imbricated before the seeds were 

 shed. The scales become very small towards the base. The summit 

 is abraded, exposing the end of a somewhat slender axis. Certain 

 grooved [lines on the sandy matrix between the scales show that 

 the cone was furnished with foliaceous bracts, and the marks of 

 a boring insect are visible. The specimen, which is quite distinct 

 from any other fossil or recent cone, is singularly elongated and 

 cylindrical, scarcely tapering at all from the base upward. It is 

 fortunately in excellent condition, certainly not derived from any 

 older bed, like so many of the Potton fossils, and is well cared for in 

 the Woodwardian Museum. 



Pinites Pottoniensis, sp. nov., Lower Greensand, Potton. 



The fragment, though much mutilated, fortunately shows the 

 characteristically winged seeds of Pinns in the most perfect manner, 

 entirely removing any lingering doubt as to the occurrence of 

 representatives of true Pinus as low down as the Neocomian. The 

 scales were set at an acute angle with slightly thickened recurved 

 apophyses, the form of which cannot clearly be made out, though 

 they appear to have been narrow, keeled, and mucronate. It nearly 

 resembles a type very common in the Eocene, and is of great interest 

 in many ways. It also is in the Woodwardian Museum, and was 

 obtained from the same formation. 



Another specimen evidently represents a third species from the 

 Wealden of Brook, with scales very closely resembling a common 

 Barton and Bracklesham tj'pe, but its fragmentary condition scarcely 

 renders it advisable to attach any specific name to it. 



The accompanying list comprises all the British Cretaceous 

 Coniferse previously known up to the present date, though there is no 

 doubt that many new and undescribed forms exist in collections.
