68 OTOZAMITES. 



V. 27453. 12'5 cm. long. Seven pinnae on one side : largest 

 4'2xl6 cm., smallest 3'8xl'2 cm. Rachis appears to be 2'5 mm. 

 Venation good, upper pinnse slightly auriculate, in the lower seg- 

 ments the ariculate base is more distinct. Cf. Pterophyllum 

 oblong ifolium, Kurr. Ecclesbourne. Rufford Coll. 



V. 2090. Part of a rachis and four pinnae. Pinnse long, not 

 overlapping, about 3 cm. apart, of similar form to those of V. 2912. 

 Ecclesbourne. Presented by P. Rufford, JZsq., 1889. 



V. 2364. Portion of a single pinna; compare with some of the 

 lower pinnae in V. 2740 ; broad and short, 5 x 3'8 cm. Very 

 different in appearance from V. 2364, but probably the same 

 species ; in V. 2122 we have the same kind of divergence in the 

 form, of the segments as between the two specimens V. 2364 

 and V. 2364^. Ecclesbourne. Rufford Coll. 



O. Klipsteinii var. longifolia, mihi. 



V. 2122. PI. VII. Figs. 1 and 6. Rachis 43cm. long; 15 

 pinnse on one side. The pinnse in this specimen are of the 

 longer and narrower form. The smallest and lowest segment 

 measures 7'5 X 2'5 cm. ; the uppermost and longest 8'4 X 2 cm. 

 The lowest pinna connects such an example as this with V. 2912, 

 V. 2090, V. 2740, etc. Pinnse separate, bases in the lower part 

 of the frond 3'5 cm. apart, the two uppermost separated by 

 2'5 cm. Venation not quite so distinctly seen as in some other 

 specimens ; the lower pinnae show very clearly the auriculate 

 form of base. 



V. 21225. This specimen, 20 cm. in length, is very imperfectly 

 preserved. The pinuse are of the longer and narrower type, 

 and agree fairly well with those of Zamites tenuinervis, Font., 

 but the distinctly auriculate form of the base and the manner 

 of insertion on the rachis seem to sufficiently distinguish the 

 specimen from the Potomac species, and to connect it with the 

 other forms of Otozamttes Klipsteinii var. superba. Possibly it 

 would be better to designate such forms as V. 2122, V. 21223, 

 V. 2123fl, etc., 0. Klipsteinii var. longifolia. Between this 

 specimen and V. 2122 there is the closest similarity. Eccles- 

 bourue. Rufford Coll.
