apex like that seen in the fragment represented in text-fig. 13, C. The venation is 

 obscure, but the veins seem to be more numerous than in the pinna shown in the text- 

 figure. This specimen may be compared with Pterophyllum longifolium Brongn. 

 figured by Andrae,* but the agreement with the English species is sufficient to justify 

 the employment of Leckenby's designation, though it is impossible to feel certain as to 

 identity in the case of so imperfect a fragment. 



Text-fig. 13, C, shows a fragment of lamina with a bluntly rounded apex characterised 

 by the strongly upward curve of the lower margin ; the base of the pinna is expanded. 

 The veins, of which there are about fifteen in the segment, 1 cm. broad, are clearly pre- 

 served. The two specimens (photo. 13 and the text-fig. 13, C) present a striking agree- 

 ment with some of the specimens from the Yorkshire strata figured in vol. i. of the 

 Jurassic Floi-a, pi. iv.

A specimen in the Gunn collection from an unknown locality, possibly Brora, agrees 

 very closely with the type-specimen of Carruthers which he described from Brora, as 

 also with his other Brora species, Yatesia crassa and Y. Joassiana. A compressed 

 pith-cast, like those seen in some of Carruthers' fossils and in that figured by Schknk t 

 from the Wealden of Germany, is partially enclosed in a cylinder of contiguous leaf-bases, 

 the larger of which measure 2 "5 x 1 cm. ; the larger leaf-bases pass into a broad band of 

 smaller ones, as in Carruthers' specimens. I have elsewhere \ expressed the opinion 

 that there is no real distinction between the casts placed by Carruthers in Yatesia and 

 Bucklandia. With the exception of Bemiettites Peachianus, which shows the fertile 

 shoots characteristic of that genus, the Cycadean stems described by Carruthers from 

 Sutherland appear to be of the same type : they agree with modern Cycadean stems in 

 the absence of lateral flowering axes. 



Otozamites, Braun. 



Otozamites sp. (PI. V. fig. 84.) 



The material from the Sutherland plant-beds includes a few fragments which appear 

 to be portions of pinnae of the Cycadean genus Otozamites. One of these is seen in 

 fig. 84, in which the numerous fine veins are shown to spread from the incomplete base 

 and to pass in a gradual curve towards the edge of the lamina. In the absence of well- 

 preserved pinnae it is difficult to distinguish those of Otozamites from such segments as 

 are characteristic of the species Zamites Carruthersi, but on the whole fig. 84 presents 

 a closer agreement with a pinna of Otozamites.
