Mr. G. R. Vine on Species of 



last type, which is simihir in some respects to R. venosa, 

 Uh-ich *. 



In addition to my own observations I have the evidence 

 of a most careful observer as to the existence of RhopaJonaria 

 in the Ludlow rocks. In 1881, J. D. Longe, Esq., of Chel- 

 tenham, sent me a series of sketches (fig. V,), with the 



Fio'. V. 



Rhopulonaria, Ulrich, from tlie Ludlow rocks. Figures supplied by 

 J. D. Longe, F.G.S., Cheltenliam, 



following remarks : — " I also enclose a sketch of a very 

 abundant, encrusting, creeping * stoloniferous ' form, which I 

 have on shells (Sjnrifer) from some Upper Silurian bed .... 

 probably Ludlow." These beautiful forms are different from 

 any known to me in the Wenlock shales, and their publica- 



* Not similar to his figures, but similar to some cells seen on the spe- 

 cimen of Ulrich's species in my o-wii cabinet.
