 Fragments of this beautiful species are present in these Upper 

 Shales, but the cells are either obscured by foreign matter, or the 

 specimens are partly crystaUised, and under these circumstances it is 

 difficult to trace the whole of the characters. In one or two frag- 

 ments, however, all the characters are clearly traceable, (i) The 

 alternate lanceolate oval cells; (2) the broad tuberculated mesial 

 ridge ; (3) the tuberculated peristome of the cells ; and (4) the 

 beautiful longitudinal striae on the reverse. Although not so perfect 

 in the ornamentation as the Hairmyres examples, stiU the chief 

 distinguishing features are present, and are truly indicative of the 

 normal type.

 Very small but characteristic specimens of this species are also 

 present in the Northumbrian Shales, and though most of the fragments 

 are far from perfect, still we can speak of them as identical with those 

 of the Yorkshire Shales at least. None of the examples show the 

 mode of branching or the twist of the stem, as in the Scotch fragments.
