Palceosoic Fossils. 35o 



the whole fronds like the magnificent one figured by Mr. C. S. 

 Prosser.* In Australia there is a very similar species A.hoivitti 

 M'Coyi which Feistmantel compares with A. hiherviica from 

 Kilkenny and Berwickshire.' All these allied forms are from the 

 Upper Devonian.

The characters of this fossil agree with those of L. notJiimi, 

 Unger'' as far as they are shown ; the two specimens which I unite 

 under the new species have rhombic impressions, which, however, 

 show no signs of division into leaf scar and cushion ; they are 

 contiguous, wider in a lateral than in the horizontal direction in 

 parts of the larger specimen, but equal in diameters in the smaller 

 specimen, and larger than broad in parts of the larger specimen. 

 The larger specimen shows a raised reticulation of the borders of 

 the leaf bases, with sunken areas in between. In some of the leaf- 

 base areas there is a slight protuberance near the upper corner, 

 which I take to be the mark left by the leaf-trace bundle. In the 

 smaller specimen there are larger rounded protuberances fixed 

 centrally in the scar areas, which are bordered by broad walls. 

 The larger specimen agrees most neai-ly with the specimen of 

 L. notJmm from New South Wales, figured by Feistmantel in 

 Plate I., fig. 4,* while Carruthers' fig. 8, PI. XXVI., is very 

 similar. Mr. Carruthers compares the Queensland specimens with 

 Leptophloeum rhomhicum,'DAV/son,^ from the Upper Devonian ol 

 North America,'' a comparison which our specimens appear to con- 

 firm. The decorticated stems, which I refer to the species 

 L. kowiense n.s\i.,m-dy probably belong to this form. The identi-
