an acute bifid apex, and a ridge passing up the middle of tiie fruit. 

 The following fruits probably belong to this species : — Carpolithes 

 corculum, Sternb. Fl, Vorwelt. t. 7, f. 6. Cardiocarpon apiculatum, 

 Gopp. and Berg., Fruct. et Sem. Lith., p. 23, pi. ii., fig. 32. G. 

 operculatum, Gopp. and Berg., I.e., p. 23, pi. ii., fig, 21. C. cornulum, 

 Dawson, Quart. Journ. Geol. Soc, vol. xviii,, p. 324, pi. xiii., fig. 23,

 C. obliquiim, Dawson, Quart. Journ. Geol. Soc, vol. xviii., p. 324, 

 pi. xiii., fig. 25 ; Pre-Carb. Floras, pi. xix., fig. 225, 226. 



The specimen figured was found by Mr. Charles W. Peach, at the 

 Cleuch, near Falkirk, in August, 1870.

2. C, anomalum, Carr., Woodcut, Fig. 3 (Antholitlies anomalus, 

 Morris, Geol. Trans., 2nd ser., vol. v., p. 500, pi. xxxviii., fig. 5. 

 Exclude the figure on the right). Spike with alternate or sub- 

 opposite crowded axillary axes, slender and elongated, bearing many 

 linear leaves, and several slender pedicels ; primary bracts long, 

 slender, and straight ; fruits small, margined. Perhaps Cardiocarpon 

 acutum, Brongn., in Lindl- and Hutt. Foss. Flora, pi. 76, may be 

 the detached fruits of this species. The base of the spike is drawn 

 in the accompanying wood-cut ; the principal figure in the plate 

 accompanying Mr. Prestwich's Memoir exhibits a considerable por- 

 tion of its upper part. The detached fruit is twice the natural size. 

 The fracture exposes the seed in the interior, and shows also the 

 thickness of the pericarp, which is always flattened in the specimens 

 preserved in shale. 



5. Coniferous Wood, 



The first sections of fossil plants prepared by Nichol when he dis- 

 covered the method of slicing them for microscopic inspection, were 

 the famous ' Araucarian ' trees found in Craigleith Quarry, near 

 Edinburgh. When Lindley described these trees in his Fossil 

 Flora, he gave reasons for doubting the close af&nity which had
