Palceozoic Species mentioned in "Fossil Floral 365 



Rcmarhs. — This genus, so long thought by British botanists 

 to be founded on badly-preserved specimens of " Uloden- 

 dron^' has been shown by Zeiller/ from a specimen presented 

 by Hutton to the Museum d'histoire naturelle, Paris, to be a 

 true genus, with which Boulay's genus Rhytidodendron is 

 synonymous.- Even decorticated specimens of Bothrodendron 

 can be generally determined from the excentric umbilicus of 

 the large scars. 



PL Ixxxii. Antholithes Pitcairni^e, L. and H. 

 Locality. — Felling Colliery. 



Horizon. — Lower Coal-Measures. Shale associated with 

 the Low Main Coal. 



Bemarks. — See notes under Cardiocarpon acutum. 



PI. Ixxxiv. Pecopteris repanda, L. and H. 



Locality. — Jarrow Coal-Mine. 



Horizon. — Lower Coal-Measures. 



Bemarks. — The type of this species is not in a good state of 

 preservation, either for understanding the characters of the 

 plant or for comparing it with other species. 



PL Ixxxiv. Halonia (?) tortuosa, L. and H. 



Locality. — Sandstone Quarry, near South Shields. 



Horizon. — Lower Coal-Measures. 



Bemarks. — This is probably only a different condition of 

 the fossils named Halonia regidaris, which are tlie fruiting 

 branches of a Lepidophloios. 



PL IxxxvL Halonia gracilis, L. and H. 



Locality. — Low Moor, Yorkshire. 



Horizon. — Middle Coal-Measures. 



Bemarks. — This is probably a Lepidodendron. In the 

 Ironstone nodules of the Dudley Coal Field and elsewhere, 

 I have seen specimens of Leindodcndron, which, from 

 unequally developed dichotomy, have a somewhat similar 

 pinnate appearance.
