FOREST OF WYRE AND TITTERSTONE CLEE HILL COAL FIELDS. 1051 



two times at fig. 2a, has somewhat closer placed leaf scars than the examples figured 

 by Boulay and Zeiller, but is otherwise quite typical of the species. According to 

 Zeiller, the distance of the leaf scars apart varies from 45 to 50 mm. ; on our 

 specimen they are only about half that distance from one another, but this character 

 is one which is subject to great variation. 



The ornamentation both above and below the leaf scars is very delicate, and in 

 some cases appears to be absent. The longitudinal striation is also very faint, so 

 that the ribs might almost be described as smooth. This is seen on fig. 2, and fig. 2a 

 shows the slight ornament the cortex possesses. 



I refer to this species provisionally the specimen given on PI. Ill, figs. 3 and 3a. 

 Here the leaf scars are placed closer to each other and, though not much more so than 

 on one of Botjlay's figures, are a little more oval ; but the smooth longitudinally 

 striated surface of the cortex is similar to that of the specimen described above. 

 This is not well seen on the figures, as they have been photographed with the light 

 striking them parallel with the ribs, to show more distinctly the form of the leaf scars. 

 I have failed to distinguish any definite character on this specimen by which it can 

 be separated from the example given at fig. 1, except in the occasional occurrence of 

 a faint plumose ornamentation immediately above the leaf scar (fig. 3a). 



I am inclined to think that the specimen figured by M. Deltenre # as Sigillaria 

 nudicaulis does not belong to that species. He gives no description or enlargement 

 of the specimen, but so far as one can observe from the figure there seems to be a 

 distinct band of ornamentation occupying the central area of the ribs and connecting 

 the leaf scars. This can be seen on the upper right-hand portion of his figure. The 

 plant appears to be similar to a specimen I have from the Yorkshire Coal Field, but 

 which I regard as specifically distinct from Sigillaria nudicaulis Boulay. 



Both of the specimens figured here are from the same locality and horizon. 



Locality. — Kinlet Colliery, 1 mile S.W. of Highley, Shropshire. 



Horizon. — Shales associated with Brooch Seam. Westphalian Series. (Fig. 2, 

 Pr. 1530; fig. 3, Pr. 1487.)

 descriptione). 



Description. — Stem ribbed, furrows straight, leaf scars distant, sub-hexagonal, 

 longer than broad, or about as broad as long ; upper margin round with very shallow 

 notch, lower margin obtusely pointed or rounded ; lateral angles rounded, distinct, 

 and from which descend two decurrent furrows which first bend slightly outwards 

 and then turn inwards towards each other, dying out before they reach the next
