XXXIX] OTOZAMITES 543 



and by their more orbicular lamina (fig. 606, B). In habit the 

 fronds agree closely with the Fern Nephrolepis Duffi. Leckenby's 

 species, Otopteris tenuata 1 , is probably the same as Zigno's 0. 

 Bunburyanus, the type-specimen of which in the Padua Museum 

 consists of a long and narrow frond with leaflets not exceeding 

 8 cm. in length ; the rachis is hidden by the imbricate auriculate 

 bases of the leaflets. Feistmantel 2 refers to this species some 

 pieces of very narrow fronds with overlapping pinnae from 

 Upper Gondwana beds in India. A still smaller form is described 

 by Moller 3 from Bornholm as 0. tenuissimus, and 0. Bunburyanus 

 is recorded from the same flora. 0. Feistmanteli Zig. 4 agrees 

 in the form of the frond and in its short and broad pinnae with 

 0. Bunburyanus. 



Otozamites bengalensis (Oldham and Morris). 



This Indian species from the Rajmahal Hills 5 and specimens 

 of the same type from the Cutch flora described as 0. contiguus 

 Feist, afford another illustration of long and narrow fronds with 

 short and relatively broad pinnae. The drawings published by 

 Oldham and Morris accurately represent the specimens : the 

 longest frond is 21 cm. long and neither end is complete (fig. 607) ; 

 it is 9 mm. broad at the narrower end and 1*5 cm. at the broader 

 end. The rachis is represented by a deep and broad groove; 

 the actual bases of the leaflets are not preserved, but their position 

 shows that they were attached to the upper face : this is clearly 

 seen in the specimen described by Feistmantel as 0. contiguus 

 which shows also that the lamina is auriculate at the upper edge 

 of the base. The pinnae vary in shape; the smaller ones are 

 characterised by a strongly curved lower margin and the upper 

 edge is slightly curved or straight, while the larger leaflets have 

 more parallel edges and blunter rounded apices : the latter form 

 is well shown in the specimens unnecessarily distinguished by 

 Oldham and Morris as var. obtusa.
