like, but not identical with, that of Pinus Slrolus. The fossil 

 seems to me to lie midway, in general aspect, between P.Strobus 

 and P. exceha. 



V. 3349. Type-specimen, PI. X, figs. 2, 3. Figured, Mantell, 

 1846, pi. ii, fig. 1 ; Carruthers, 1866 B, pi. xx, fig. 5, 

 and 1867, pi. Iviii, fig. 5 [same plate]. The lower 

 half of the cone, split into two unequal portions. In 

 one of these the stalk at the base can be well seen 

 still, though evidently the smaller basal scales have 

 been broken away. The crescent-shaped, somewhat 

 thickened edges of the scales are very clear on one 

 face. The cone is irregularly split in a tangential 

 direction, which leaves a surface passing partly through 

 the axis of the lower 3 cm. Here the attachments of 

 some of the scales can be imperfectly seen. The scales 

 appear to measure from 3 to 4 cm. from attachment 

 to tip. Toward the middle of the break, the angle 

 bends abruptly, so that the tangential surfaces of the 

 split scales are exposed, the central one having the 

 broken-open empty testas of two seeds adhering. The 

 upper end of the specimen shows the cone-scales, seeds, 

 and axis irregularly broken across (PI. X, fig. 3). 



V. 3349 a. Figured, PI. X, fig. 4; PI. XI, fig. 3 ; text-figs. 30 

 & 31. Transverse section of part of the above cone. 

 In this the overlapping thick scales show particularly 

 clearly. Two seeds attached to their scale can also 

 be seen at the upper part of the section (PI. X, fig. 4, 

 s.). All the details of the anatomy, as described 

 above, can be made out in this section. The scale 

 marked z in the figure being particularly good for the 

 vascular anatomy, and the scale marked x for the 

 tissues of the wings. 



V. 3349 b. A poorer and rather pulverised transverse section, 

 similar to the above. Two of the scales on the left 

 hand of the section show their tissues, as well as the 

 wings, in a good stale of preservation.
