was figured by Feistmantel.^^ It has, however, been suggested 

 both by Seward*^ and Arber*^ that the specimens should perhaps 

 more correctly be referred to 0. Feistmanteli. Mr. W. S. Dun has 

 been kind enough to send me tracings of Zigno's original figures 

 of the latter species and comparison of these with Queensland 

 specimens leaves no doubt of the identity of the two. 



Localities : — {Walloo7i Series) : Near Thane's Creek, Warwick 

 (F 339) ; Engelsburg-Boonah District (1420). 



Figured specimen : The original of Plate 8, figs. 2 and 3, is 

 specimen F 339 in the Collection of the Queensland Geological 

 Survey. 



Otozamites cf. Mandelslohi, Kurr. 



(Plate 8, figs. 4, 5.) 



Frond linear, narrow, with a breadth of about 1-5 cm. The 

 pinnae are rather orbicular, 8 to 9 mm. long and 7 mm. wide, with 

 an obtusely rounded apex ; they overlap slightly and are auriculate 

 at their upper margin. They are attached to the upper surface of 

 the rachis. The veins are numerous, fine, divergent, and dichotomous, 

 there being about 15 to 20 in a space of 5 mm. 



The specimens described here differ from those which have 

 been referred to 0. Feistmanteli. The pinnae are smaller and 

 orbicular, and the venation is much finer than in the latter species. 

 The only figures of 0. MandelsloJii available to the author are 

 those of Wieland*^ from the Liassic flora of the Mixteca Alta. 

 Although the resemblance to these figures is not sufficient to indicate 

 identity, it is sufficient to warrant a close comparison. The speci- 

 mens previously referred to 0. Mandelslohi by Tenison- Woods and 

 Feistmantel have been identified with 0. Feistmanteli, Zigno.^^ 



Localities : — {Walloon Series) : Darhng Downs, near Too- 

 woomba (F 750). 



Figured specimen : The original of Plate 8, fig. 4, is specimen 

 F 750 in the collection of the Queensland Geological Surve3^
