2. Schizoneura. (Plate 50.) 



This specimen is taken to represent the upper portion of 

 astern of Schizoucura aoiuliranensis (australis), showing 

 seven areas of leaf attachment, the leaf-sheaths being split 

 into numerous linear segments. This may be compared to 

 Feisunauters figure, though in our case the specimen is 

 more delicate and of smaller proportions. From the abun- 

 dance of large Equisetaceous stems in these shales it is 

 clear that the Australian Schizoneura attained to as great 

 a size as the Indian, although no perfect specimens have 

 been found as yet. 



A large stem showing two nodes is figured (Plate 51). 

 It is impossible in the absence of foliage to separate the 

 stems of Phllotheca and Schizoneura, but from the associ- 

 ation there appears to be no doubt about the reference. So 

 far as I am aware no Phyllotheca has been collected from 

 these beds yet. 



3. Rhipidopsis ginkgoides, Schmalhausen (?) var. Suss- 



milchi, nov. (Plate 51). 

 The leaves referred to this species are represented by 

 two imperfect specimens shown on Plate 51. One of these 

 shows the leaf divided into three main segments, very 

 wedge-shaped, tapering markedly towards the point of 

 attachment; two of these segments show accentuated 

 lobation in themselves. The point of attachment to the 

 stem or stalk is not preserved. The venation is extremely 

 fine, dichotomous several times, and in its degree of develop- 

 ment more like that of one of the Ginkgos than Noeggera- 

 thiopsis. The terminations of the lobes are rounded. 

 There is room for considerable doubt as to whether this can 

 be regarded as a Ginkgo or as belonging to such a type as 

 -Vot > :/</emfcJtiop•i« f , but though this latter genus may adopt 

 a palmate habit as figured by Dana, still so far as the Aus-
