LEPIDOSTROBUS MINOR (Goode). (PI. 9. figs. 22, 23, 24, 25.) 
Sporophylls detached. 
1913. Lepidophyllum minus, Goode, in Quart. Journ. Geol. Soe. vol. Ixix. p. 266, pl. 28. 
figs. 3 & 5. 
1914. Lepidophyllum minus, Arber, in Quart. Journ. Geol. Soc. vol. lxx. p. 78. 
1914. Lepidophyllum brevifolium, Arber, in Phil. Trans, Roy. Soc. ser. B, vol. cciv. p. 386. 
Diagnosis,—Sporophyll small, sagittate, up to 15 mm. long and 5-7 mm. 
wide at the broadest part. Pedicel slender, elongately wedge-shaped, 
5-7 mm. long and 2-3 mm. wide at the broadest part. Lamina short, tri- 
angular, nearly equilateral, about 1 em. long, lower angles somewhat 
recurved towards the pedicel. 
Remarks.—This species stands near to L. brevifolius, but the pedicel is 
larger, the lateral margins straighter, and the angles are more acute. The 
basal angles of the pedicel are more prolonged and curved downwards. 
The specimens from the Wyre Forest which in 1914 I attributed to 
Lepidophyllum brevifolium should be included under this species. 
Nos. 2902, 2903. One of the type-specimens from Pembrokeshire is 
refigured (natural size) on Pl. 9. figs. 22 & 23. 
Other specimens from the Kent coalfield are figured on Pl. 9. figs. 24 
and 25, both natural size. 
No. 2448. Fig. 24 is a small example, only 12 mm. long. 
No. 2295. Fig. 25 shows a larger specimen 18 mm. long, and a very 
broad example 9 mm. across. 
Type. No. 2902-3. Carbon. Plant Coll., Sedgwick Museum, Cambridge. 
Distribution. Middle Coal Measures.

LEPIDOSTROBUS MOYSEYI, sp. nova. (Pl. 9. figs. 26 & 27.)
