FOREST OF WYRE AND TITTERSTONE CLEE HILL COAL FIELDS. 1053 



From typical Sigillaria laevigata Brongt.* the specimen figured here differs in 

 the presence of the furrows extending upwards from the leaf scars and the delicate 

 plume-like lines which spring from the neighbourhood of the ligule pit, as well as in 

 the more oblong form of the leaf scars than usually shown on Sigillaria laevigata, 

 and these differences make me hesitate to refer Sigillaria distans to that species ; 

 but it is possible that these differences may be dependent on the different ages of 

 the specimens under comparison. 



I figure here also a portion of a specimen of a Sigillaria from the " Bottom Coal," 

 Chimney Colliery, Angelbank, Titterstone Clee (PI. V, figs. 10, 10a). This I also refer 

 to Sigillaria distans Sauveur. The leaf scars are smaller in proportion to the width 

 of the ribs, and occupy rather less than one-third their breadth. In form they vary, 

 some being oval, and others rather broader than long (fig. 10a). The leaf scars, which 

 have a slight ornamentation above them, as already described (fig. 10a), have the 

 upward-extending lines from the top margin and the decurrent lines from their 

 lateral angles. *In this example there is perhaps a nearer approach to Sigillaria 

 laevigata Brongt., but the characters possessed by the specimen make me hesitate to 

 refer it to Brongniart's species. On the other hand, in all its salient characters it 

 agrees with the other specimen (PL IV, fig. 4) which I have referred to S. distans 

 Sauveur. 



From Sigillaria nudicaulis Boulay, Sigillaria distans differs in the presence of 

 the long decurrent furrows from the lateral angles, as well as in the furrows which 

 extend upwards from the upper margin of the leaf scar, differences which seem to 

 preclude the possibility of uniting these two species, t 



I therefore for the present prefer to regard Sigillaria distans Sauveur provision- 

 ally as a distinct species, though believing in the possibility of its having been founded 

 on a young condition of Sigillaria laevigata Brongt.

Description. — Stem ribbed, ribs straight, broad in proportion to size of leaf scar, 

 smooth. Leaf scars distant, small, broader than high (transversely oval), upper
