V. 3623. PI. VIII, Fig. 1. Also figured hy Seward (97 1 ), 

 p. 326, pi. xxiii, fig. 2, and text-figs. 2a-e on -p. 327. 



A part of this fossil is figured on PI. VIII, Fig. 1, showing 

 the spirally arranged leaf-scars, which in the upper portion are 

 fairly well preserved. The entire specimeD, which is a sandstone 

 cast, measures 18 cm. in length and 12 cm. broad. The leaf-scars 

 are 9 mm. broad and 7 mm. in height. The stem had become 

 decorticated to some extent before preservation took place, especially 

 in the lower portion, consequently the characteristic features of 

 a Sigillarian leaf- scar — the central vascular print and the two 

 lateral crescentic prints of the parichnos — are not preserved. But 

 on one or two of the scars in the upper portion the vascular print 

 may be seen and also the parichnos, which is usually represented 

 by a V-shaped projection. Enlarged drawings of several of these 

 scars, accompanied by a full description, have been given by 

 Mr. Seward. 1 



The leaf-scars are closely set, and between them occur narrow 

 sloping ridges of sandstone, which represent the grooves separating 

 the leaf- scars in the living state.

A small piece of a stem, partially decorticated, showing a cast 

 of the internal tissues (Syringodendron type). On one side, 

 however, the leaf-scars are plainly seen, and they resemble those 

 of the previous specimen.
