Westphalens, pi. xvii.). Neuropteris heterophylla and Neu- 

 rojpteris Loshii are now known to represent only different 

 portions of the same species. 



Localities. Blaes between Kiltongue and Drumgray Coals, 

 Whiterigg, near Airdrie ; cutting, new Caledonian Railway, 

 Airdrie ; roof of Kiltongue Coal, Mount Vernon (at the 

 two last-mentioned localities pinnules of the so-called Cyclo- 

 pteris trichomanoides also occurred) ; Bent Colliery, about 1| 

 mile E. of Bothwell.

Remarks. The synonymy of this species is in a very un- 

 satisfactory state ; I therefore refrain from giving any further 

 references. 



Neuropteris Scheuchzeri, which is one of the earliest figured 

 ferns, occurs plentifully in some of the English Coal-fields j 

 but the examples from Whiterigg are the first I have seen 

 from a Scotch locality. Some of the specimens are very 

 good, and showed attached to the main axis large cyclo- 

 pteroid pinnules analogous to those to which reference has 

 already been made in regard to Neuropteris heterophylla , 

 Brongn. 



Locality. Whiterigg Pit, near Airdrie.
