Heads, New Zealand, which are figured here. Halle(l) has also figured recently, from 
the Cretaceous of Patagonia, similar pinnae as Cladophlebis australis. A very similar 
ii not identical fossil occurs also in the Cretaceous of the Canadian Rocky Mountains(2). 
Cladophlebis australis is almost everywhere in the Mesophytic floras of New Zealand 
the most abundant of all species, without exception.

Diagnosis .—The following diagnosis of this species was given by Seward in 1900 
(see above) : “ Frond bipinnate, large, with long spreading pinnae attached to a 
comparatively slender rachis. Pinnules falcate, acutely pointed, usually finely dentate, 
attached by the whole of the base ; the longest pinnules may reach a length of 
3-4 cm. Venation of the typical Cladophlebis type ; a well-marked midrib giving 
off secondary dichotomously forked veins at an acute angle. Towards the apex of 
the frond the pinnules are shorter and broader than the longer and narrower segments
