A specimen in the Britisli Museum collection (V. 3433 ; PL IX. 

 Kg. 2) is probably the original of the drawing given in the Geology 

 of Cheltenham under the name Stricklandia acuminata. 



The two specimens represented in Text-fig. 10 and in Fig. 2, 

 PL IX. are the only examples from the Stonesfield Slate that I 

 have seen which can be referred to the genus Baiera. "Without 

 more material it is hardly possible to determine the species with 

 oonfldence, but the imperfect leaves agree so closely with the 

 Inferior Oolite specimens for which Nathorst's name has been 

 adopted, that they may be reasonably referred to his species. The 

 fossil shown in Text-fig. 10 might be taken for Sagenopteris, but 

 the lobed character of the lamina and its probable identity with 

 the more complete example shown in PI. IX. Tig. 2 lead me to 

 .speak of it without hesitation as Baiera. 



The drawing of Striclclandia acuminata in the Geology of 

 Cheltenham would be valueless as an aid to identification were it 

 not probable that the specimen (V. 3433) reproduced on PL IX. 

 Pig. 2 represents the original leaf.
