WiLLisoNii, Moore. (Plate XXXI. — B.) — An interesting 

 variety found near Whitby by Mr. W. Willison, having 

 elegant depauperated fronds. Finns remote, pinnules remote 

 and irregular, the intervals being occasionally as much as half 

 an inch, unequal in size, irregularly dentate, decurrent in a 

 marked degree behind. Occasionally laciniately depauperated. 

 For fronds of this singular Fern, I am indebted to Mr. W. 

 Willison, of Whitby.

Beevorie, Lowe. (Fig. 201.) — A very handsome Fern 

 found by Miss Beevor near Coniston in the Lakes. This 

 variety is perhaps the nearest approach to Pinderii, yet 

 differs in having the pinnae so close together, and the 

 pinnules so large and leafy as to touch each other, except 

 the basal pair of pinnae, which are a quarter of an inch 

 below the next pair. The basal pinnules of each pinna 

 overlap the costa and half conceal it. The pinna) bear a 

 close resemblance to Pinderii, yet are blunter and more 

 rounded at their apices, and they do not become shorter and 

 smaller, as in that variety. The stipes and rachis is densely 

 clothed with scales of a rich golden brown. The sori consist 

 of a single row of spore-cases along the midrib of the pinnae, 

 and are confined to the apex of the frond. With the 

 exception of the upper four or five inches, the frond is 

 barren. Length of frond thirty inches, the apex acuminate. 

 ;My thanks are due to Miss Beevor, of Coniston, for fronds.
