56 OTOZAMITES. 



V. 2172. This specimen was erroneously included under Tcenio- 

 pteris Beyrichii in Vol. I. (p. 126). 



V. 2234a. 5 mm. broad. In a length of 4-2 cm. there are 

 about 23 divisions in the lamina; in the same length of V. 2171J, 

 the lamina shows no divisions. At one end the segments gradually 

 decrease in size until they almost disappear. Ecclesbourne.

Genus OTOZAMITES, Braun. 

 [Minister, Beitrag. Petrefact. Heft vi. 1843, p. 36.] 



The name Otozamites, instituted by Braun in 1843, was defined 

 by him as follows : Leaves pinnate, pinnae alternate and ap- 

 proximate, auriculate, and attached by a portion of the base ; 

 veins radiating from the point of attachment to the margins of 

 the segments. 



This author includes Zamites falcatus (Sternb.), Z. Bucklandi 

 (Brong.), and Z. Irevifolius (Braun, etc.) as species of his new 

 genus ; Z. falcatus was first figured by Sternberg * as Odontopteris 

 fulcata, and 0. Bucklandi was described by Brongniart in 1825 as 

 Filicites Bucklandi var. Britannica 2 ; both of these species were 

 assigned by Morris 3 to his genus Ptilophyllum. Brongniart adopts 

 Braun's generic name, and points out that Otopteris, Lindley and 

 Hutton, corresponds to Otozamites of Braun. This genus affords 

 another example of confusion in nomenclature arising from a 

 difference of opinion as to the botanical relationship of the fossil
