Ficoides rigida. 



Emmons, Taconic System, p. 67, pi. v. fig. 2. 



Agriculture of New York, pi. xvii. fig. 2, 1846. 

 Jates, Trans. Geol. Soc. 2nd ser. vol. ii. p. 256, pi. xxvii. fig. 1. 

 Remarks. This species approaches somewhat closely to Bythotrephis gracilis 

 var. crassa, but appears to branch more freely than that species. Mr. Jates 

 has figured a specimen from Colmore's Farm, Bromsgrove, Lickey, which is 

 evidently referable to this Alga. 

 Horizon. Upper Silurian, Wenlock Limestone. 

 Locality. British. Shropshire, Malveru. 



Bythotrephis, sp. 



Remarks. The specimens placed here may be only a variety of Bythotrephis 

 divaricata, but are too fragmentary to allow of a satisfactory determination. 

 Horizon. Upper Silurian. 



Localities. British. Herefordshire : Leiutwardine. Shropshire : Ludlow : 

 Malvern Tunnel. 



ALGOIDAL (?) IMPRESSION. 



Remarks. These small fossils, which appear to be algoidal, are branched, 

 and have their branchlets covered with fine segments, giving to them a 

 plumose character. All the specimens are fragmentary, but I am not aware 

 of any described species to which they can be referred. 



Horizon. Upper Silurian. 



Localities* British. Herefordshire : Bow Bridge, near Leintwardine : 

 Brandon Camp.
