70 OTOZAMITES. 



specimen (V. 2734) may be the basal portion of a young partially 

 expanded frond of the same species (0. Xlipsteinii], of which 

 V. 2336 (PI. I. Fig. 3) is the apical termination of a young frond, 

 but it would hardly be wise to do more than offer the suggestion. 

 In V. 2336 the rachis appears to be very slender ; here, on the other 

 hand, it is distinctly strong and broad : how far this constitutes an 

 important difference, and how far it is due to one specimen 

 being the terminal portion and the other the basal portion, or to 

 differences in the manner of preservation, is difficult to decide. 

 The individual pinnae are very similar to, and possibly identical 

 with, the isolated segment figured by Dunker 1 and Schenk 2 and 

 now classed with V. 2336. Ecclesbourne. Ruff or d Coll.

V. 2926. This small specimen shows ? pinnae attached to the 

 upper surface of a rachis. It may belong to the same species 

 as V. 2734 (PI. II. Fig. 4), but of this there is no obvious 

 proof. It agrees very closely with Heer's Portuguese species 

 0. Heileiroanus. 3 The upper lobes of the pinnae are more 

 prominent than the lower. Ecclesbourne. Rufford Coll.
