Locality? I suspect this is from Ballinore Mine, Talbragar 

 River, from the nature of the matrix, but it may have come from 

 Ipswich, Q. L. The rounded and obtuse leaves, and the close- 

 ness of the veins and venules, distinguish this species 



Alethopteris currani n.s., Plate 6, fig. 4. — This fossil, if I may 

 judge from the small fragment, appears to have belonged to the 

 division Pecopleris acrostichides of Schimper, in which the frond 

 which is pinnate and bi-pinnate, has the pinnules adherent by the 

 whole base and confluent. The veins are slender, costa disappear- 

 ing near the apex, the veins forking. Of the sori, nothing is 

 known, and the relations may have been as in other members of the 

 genus, with Asplenium. In this case, the secondary pinnules only 

 are seen, in the apex of what has been probably a portion of the 

 frond. The pinnules are falcate, oblique, oblong lanceolate, slightly 

 serrated at the upper edge, rounded at the apex into a blunt point, 

 nearly opposite, adherent by the whole base, confluent. Costa of 

 the pinnules emerging from the rachis at a very acute angle ; veins 

 few, conspicuous, forking once, the venules reaching the margin 

 at the re-entering angle of the serrations, apical pinnules acute. 

 Length of fragment, 25 ; greatest width, 15 ; length of longest 

 pinnule, 10 ; width of base, 6 ; all millimetres. 



Ballinore coal field. The only species to which I can compare 

 this, is to the preceding A. ivhitbiensis. The differences however, 

 are very great. The pinnules and median vein are very much 

 more oblique, the rachis stouter, and the pinnules are also 

 lobed, broader, the whole frond large, but more tender and 

 membranaceous. 



Merianopteris. Heer.* 



Sterile fronds tri-pinnate, elegant, secondary pinnae elongate, 

 segments of pinnse inconspicuous, costa arcuate, veins dichotomous, 

 the lowest two from contiguous pinnules bending towards each 

 other and anastomosing. 



This diagnosis is applied by Dr. Heer, to distinguish two species 

 of Ferns from the Upper Lias in Switzerland. The principal
