above the insertion, beyond which it gradually narrows to 

 the apex. Below this point, the lower margin turns up 

 slightly to the pedicel with great uniformity in each segment, 

 while the upper margin, with eqaal constancy, descends in a 

 nearly vertical direction for some distance, until it joins the 

 pedicel and becomes its upper border. P. lanceolatus itself 

 varies in the mode of formation of the pedicel ; thus, in the 

 type genuinus either margin may turn in more at the base 

 than the other, while in the var. Eichwaldi the leaflets appear 

 to be usually symmetrical at the base, but the regularity 

 which characterises the Scottish specimen in this and every 

 respect is against regarding it as another variety of the same. 

 In the direction and arrangement of its leaflets, and to some 

 extent also in their form and insertion, it has more analogy 

 to P. angustifolius (Eichw.), but in this the lower margin is 

 the one which is uniformly most curved to meet the decurrent 

 pedicel, and the leaflets are much more slender. The forms 

 with which comparison is thus suggested belong to the lower 

 and middle Oolites of various countries.

The third specimen belongs also to the genus Fodozamites, 

 which has been so much extended by recent research in all 

 parts of the world. This consists of a portion of a frond, 

 with long and narrow leaflets in relation to a rachis, from 

 which, however, most of them are detached, although still 

 retaining their order. Only one, which lies separate from the 

 rest, is nearly perfect ; the termination of the others is not 

 seen. They were not less than 4^ inches long, and at their 

 widest part only f inch broad. This is reached nearly 

 3 inches from the base, and throughout this distance they 

 slowly narrow to their insertion, contracting also in the 

 opposite direction to probably an acute or subacute apex. 

 They are arranged with considerable regularity at a slight 

 distance from one another, forming acute angles with the
