FKOM THE HUTTON COLLECJION. 10 



longitudinally ; pinnai and pinnules numerous, aud the latter 

 arranged close together and overlapping as in N. Loshii, and 

 not separate as represented in the drawing. 

 Loc. — Shale above the Bensham Seam, Jarrow. (H. C. 268). 



Remarks. — I adopt the term N. Loshii applied to this species 

 by Brongniart as being preferable to the vague name heterophylla, 

 as I think it will be found that most of the species of this genus 

 if not all are heterophyllous ; and another reason, it records the 

 name of a Novocastrian who did much as an early collector of 

 fossil plants, and sent away many species from this Coal-field to 

 Brongniart; and because it is the most common and characteristic 

 form of this species. Hutton's Type, No. 116, being a very bad 

 drawing, has been a puzzle to many, as also the Hutton Type, 

 No. 119, of iY Soretii; but as the Type-specimens are both in 

 the collection, there can be no doubt about their identity with 

 Brongniart's species as referred to above. Hutton's Plate 200 

 also belongs to this form, of which it is merely the imperfect 

 terminal part of a pinna. Hutton's Pecopteris adiantoides is a 

 portion of a large pinna in a young state of growth, the branch 

 of the rachis being broad from compression, at least this is the 

 appearance it has. Another specimen figured by Hutton as N. 

 heterophylla, P. P., pi. 197, does not belong to this species, but 

 is referred to N. flexuosa, Brongniart, and Plate 183 of the same 

 authors represents, I think, a pinna of another very distinct 

 species, N. auriculata.
