Prond pinnate ; pinnae more or less falcate, attached alternately 

 to the upper surface of the rachis, characterized by the strongly 

 auriculate upper edge of the base ; veias spreading in the basal 

 portion of the segments and slightly oblique to the upper edge of 

 the rest of the lamina ; apices acuminate and directed upwards. 



The species Otopteris graphica is mentioned by Bronn' in 1848 

 and by Morris* in 1854, but these authors refer to the specific 

 name instituted by Bean in manuscript, without publication ; 

 the first description and illustration of the species under Bean's 

 name is in Leckenby's paper of 1864. The fragment figured by 

 Brongniart as Filieites BuoMandi, var. gallica, from Mamers, of 

 Bathonian age, is probably specifically identical with the more 

 perfect frond figured by Leekenby ; this view is adopted by 

 •Saporta and Schimper. Considering the fragmentary nature of 

 Brongniart's specimen it is safer to regard Leckenby's specimen 

 as the type of the species and to retain the name originally 

 pi'oposed by Bean. 



Some of the Rheetic fronds figured by Schenk as Otopteris 

 Buehlandi'^ very closely resemble Otozamites graphicus, and afford 

 connecting links between that species and 0. oitusus.
