FOSSIL FLORA OF THE STAFFORDSHIRE COAL FIELDS. 173 



Fig. 2 shows portion of three parallel leafy branches which appear to spring from 

 the stem lying at their base, but I cannot observe any actual connection. This 

 specimen is enlarged 2 times at fig. 2a, where the bent-up leaves with their incurved 

 margins, and the prominent midrib placed in a furrow, can all be seen. It is also 

 noticeable on this specimen that the leaves decrease in size towards the base of the 

 branchlet (fig. 1). 



Another small specimen is given at fig. 3, and enlarged 2 times at fig. 3a. The 

 bowl- or saucer-shape form of the leaf whorls is well seen on the enlargement fig. 3a. 



If the two species be now compared, it will be seen that in Annularia microphylla 

 Sauveur the leaves are lanceolate and sharp-pointed, with involute margins and a 

 prominent midrib placed in a furrow. In Annularia galioides the leaves are much 

 broader in proportion to their length and do not end in such prolonged points. The 

 midrib is not placed in a furrow and the leaves are flat.*

Notes on the Vertical Distribution of the Fossil Plants. 



In all 154 species are recorded from the Westphalian Series of the South 

 Staffordshire Coal Field. Of these, 13 are only generically recorded, as the material 

 at my disposal was not in a sufficiently good. state of preservation for a satisfactory 

 identification or description. 



Twenty new species are described, namely, Sphenopteris deltiformis, Sphenopteris 

 Kilimlii, Coseleya glomerata, Pecopteris hepaticwformis, Neuropteris Carpentieri, 

 Palseostachya minuta, Sphenophyllum tenuissimum, Sigillaria punctirugosa, Lepido- 

 carpon Westphalicum, Samaropsis quadriovata, Tripterospermum ellipticum, Triptero- 

 spermum Joh7bsoni,Polypterospermum ornatum, Lagenostoma oblonga, Lagenostoma (?) 

 urceolaris, Rhabdocarpus Renaulti, Rhabdocarpus Oliveri, Hexagonocarpus Hooheri, 

 Whittlesey u (?) fertilis, and Dicranophyllum anglicum ; while the 10 following have 

 not previously been recorded for Britain, as far as I am aware : Sphenopteris 

 Schatzlariana Stur, sp. (emend.), cf. Sphenopteris Sancta - Felicis Stur, sp., 

 Sphenopteris Souichi Zeiller, Crossotheca Crepini Zeiller, Adiantites sessilis Koehl 

 [pro. var.), Alethopteris integra Gothan, sp., Ccdamostachys Solmsi Weiss, Huttonia 

 spicata Presl, sp., Lycopodites Meehi Lesqx., and Sigillaria cordigera Zeiller. 



Although a considerable number of species have been met with in the South
