EXPLANATION OF PLATES XII. -XIII. 



Plate xii. 

 Fig. 1. — Belmontia mitchetti, n.g. et sp. (Upper Permian of Belmont, 

 N.S. W. ). The fossil wing in situ, ( x 8J), 



Plate xiii. 



Fig.2. — Belmontia mitchetti, n.g, et sp. Base of wing, more highly mag- 

 nified, to show the region of the arculusand the cubital fork, ( x 19). 



Fig. 3. — Belmontia mitchetti, n.g. et sp. Arculus and cubital fork still 

 more highly magnified, to show bases of insertion of macrotrichia, 

 ( x 425). The arrow points to a clearly marked base of insertion on 

 the arculus itself, while an equally well marked one can be seen on 

 Cii! by following the main stem of the arrow backwards. Other 

 similar bases are to be seen on the remaining veins. (The true 

 cross-veins do not carry macrotrichia). 



(Fig. 1 enlarged from a photograph taken with a triple-extension camera, 

 magnified x4i; Figs. 2-3 reproduced from a photomicrograph taken with 

 Reichert's photomici'ographic apparatus; Fig. 3 an enlargement from the 

 negative of Fig.2).
