and gradually narrowing to the apex. Pinnules somewliat distant, 

 basal pinnules profoundly notched on either side of their base, 

 and being rounded at their apices. Margins inciso-lobate, the 

 lobes having from three to five teeth. Veins more highly 

 developed. Sori normal.

Depauperata-moxkmaxii, Monkman. (Fig. 195.) — An acci- 

 dental seedling from cristata, but exhibiting no disposition 

 whatever to crest. There are two or three slightly differing 

 forms in Mr. Monkman's collection, all as peculiar as the 

 specimens illustrated. The fronds are all different, but depau- 

 perated so greatly in some cases as to be hardly bipinnate, 

 the pinnse resembling irregularly-toothed lobes. Quite constant, 

 dwarfish, and very handsome. For fronds my thanks are due 

 to Mr. Monkman.
