56 GLOSSOPTERIS. 



■which is more linear in shape, and has an oblique lateral nervation. 

 The midrib is strong and extends to the apex, and the meshes are 

 fairly broad. It may be regarded as a narrow frond of the same 

 species, and is not unlike McCoy's G. linearis. Several other 

 linear fronds occur on the same specimen, some of which are only 

 7 mm. across. 



Newcastle coal-mines. Strzelechi Coll. 



V. 7207. PL III, Fig. 2. 



The specimen figured is a median portion of a frond of fairly 

 large size, with the broad meshes characteristic of G. Brotoniana. 

 The specimen also shows several imperfections, consisting of holes 

 irregularly arranged on either side of the midrib, similar to those 

 on other fronds which have been described as indications of sori. 

 It is almost certain, however, that these features have no 

 connection with the fructification. 



Port Stephens. Odinheimer Coll. 



52,812. PI. Ill, Fig. 1. 



A complete frond, spathulate in shape, with broad meshes. 

 The midrib does not quite extend to the apex. Numerous pustule- 

 like bodies occur scattered over the surface of the frond, which 

 have probably no connection with the fructification. Other and 

 more imperfect fragments also occur on the same specimen.

V. 7296. A piece of pink shale showing a number of fronds. 

 One of these is an almost perfect leaf, widest towards the apex, 

 and tapering gradually at the base. The meshes are somewhat 

 narrower, and more elongate than in many examples of this species, 

 but this character varies slightly among the fronds on the same 

 slab. There is also another fragment, showing the obtuse apex, 

 in which the midrib splits up into fine veins before reaching the 

 apex, a feature which may be often noticed in the fronds of this 

 species. 



On the first-mentioned leaf, two hollows are seen containing 

 three or more small bodies, which might at first glance be taken for 

 the fructification, but which are probably of an entirely different 

 nature. A triangular scale-frond, probably of G. Browniana, 

 occurs on the same slab.
