FOREST OF WYRE AND TITTERSTONE CLEE HILL COAL FIELDS. 1045 



typica has also been pointed out ; but if the figures of this plant correctly represent 

 the structure of the fossil, its belonging to Cingularia is most improbable. 



Locality. — Highley Colliery, Highley, Shropshire. 



Horizon. — Shales associated with Brooch Coal, Westphalian Series. (Fig- 1, 

 Pr. 1350 ; fig. 2, Pr. 1261.) 



Cingularia Cantrilli Kidston n. sp. 



PI. I, figs. 3-5. 



Description. — Stem, leaves, and mode of attachment of cones not known. Cone 

 large, 1'20 cm. wide, but complete length unknown. Axis stout, about 4 mm. broad, 

 ribbed and distinctly striated longitudinally. Whorls close, about 80 mm. distant 

 from each other, slightly overlapping, and formed of ten sporophylls without an ac- 

 companying whorl of sterile bracts. Sporophylls about 1 cm. long and 0*5 cm. wide, 

 united in their lower portions for about half their length, and forming a saucer-like 

 collar round the axis. A short distance below the free portions, the sporophylls form 

 a knee bending upwards and surrounding the axis as a cup-like structure divided into 

 ten truncate segments, each of which is again divided into two lappets by a cleft 

 which extends inwards rather more than half the distance of the free part of the 

 sporophyll. 



The upper surface of the sporophyll shows a furrow, which, rising at the 

 outer margin a slight distance below the apex, slopes obliquely inwards and, 



ending at the base of the cleft, divides the sporophyll into two parts. On each 

 of the two free lappets is a small circular point, and immediately within them 



on the united part of the sporophyll are two additional small circular prominences. 



These indicate the position of the four sporangia on the under side of the 



sporophyll. 



The under surface of the sporophyll shows two prominent ridges that run obliquely 



across the two lappets of the sporophyll and end at the base of the cleft. On the 



two free lappets of the sporophylls so delimited an outer concentric row of small 



circular scars is seen, one on each lappet, and on the upper part of the united portion 



of the sporophyll another inner concentric circle of small round scars occurs ; these 



scars indicate the points from which the two concentric rows of sporangia have been 



removed. 



Sporangia unknown. 



Remarks. — Only two specimens of this cone have been found, both of which come 



from the same horizon and locality. The small portion seen at fig. 3 and those given 



at figs. 4 and 5, of which fig. 5 is the counterpart of fig. 4. # 



Fig. 3 probably shows the upper surface of a portion of two fertile whorls, natural 



size, on which the sporophylls have been bent downwards, and the same specimen is 



* Fig. 4 is formed of Nos. Pr. 1256 and 1257, which are now joined together, and fig. 5 of Nos. Pr. 1258 and 1259.
