nine lines long by eight lines broad ; scar of the compact bundle 

 roundish; separate scars fewer than in U. loumilum; leaf scars 

 distant from each other, with as much free space separating them 

 as their own breadth, obovate, with decurrent base, and a scar, 

 where the vascular bundle passed out. 



I have associated with this species the name of an old class- 

 fellow, Andrew Taylor, Esq., Edinburgh, who during the past 

 summer led me to a quarry in the neighbourhood of Bathgate, 

 where he observed remains of Ulodendra, and where we succeeded 

 in obtaining specimens of this interesting species.

6. U. transversum, Eichwald, ' Lethsea Kossica,' vol. i., p. 139, 

 plate ix. Cicatrices deltoid, with the angles rounded, nearly 4 

 inches long by 3f inches broad ; scar of compact bundle near the 

 base, of a flattened horse-shoe shape, separate bundles radiating all 

 round from the cone of the aerial root descending into the stem ; 

 leaf scars rhomboidal. Meg ajphy turn majus, Presl, Sternb., ' Flora,' 

 p. 187, plate xlvi., probably belongs to this species. 



A scar half the natural size is figured on Plate XLIV., Fig. 2. 

 It belongs to a " corticated " specimen, and shows only the pits of 

 the vascular bundles belonging to the leaves.

 Museum], and South Wales [Cardiff Museum]. 



7. TJ. majus, Lindl. and Hutt., ' Fossil Flora,' plate v. Cica- 

 trices circular, 2^ inches in diameter; scar of compact bundles 

 central, compressed circular ; sears of separate bundles more or less 

 pit-like throughout ; leaf scars rhomboidal. TJ. Lucasii, Buckl., 

 ' Geol. and Miner.,' vol. ii., p. 93, plate Ivi., fig. 4 (1836). U. Lind- 

 leijanum, Presl, in Sternb., 'Flora,' p. 185 (1838). Bothrodendron

The scar figured, Plate XLIII., Fig. 4, is from a fine cast of a 

 specimen found near Swansea by Mr. Lucas.

8. U. minus, Lindl. and Hutt., ' Fossil Flora,' plate vi. (excl. 

 synonymes). Cicatrices sub-circular, from 1^ to 1^ inch in dia- 

 meter ; scar of compact bundles triangular with the angles rounded ; 

 scars of the separate bundles pit-hke on the under half, radiating 

 and furrowed on the upper ; leaf scars rhomboidal. 



The drawings by Lindley and Hutton of the last two speciea 

 are very unsatisfactory. I have never seen the cicatrices composed 

 of large flat scales, as represented there.
