LACCOPTEKIS.

Museum convinced me that it is identical with Brongniart's 

 type. Nathorst, 1 who regarded Laccopteris as a more suitable 

 generic designation than Phlebopteris, has expressed the view that 

 Phlebopteris polypodioides, P. crenifolia* and P. propinqua are 

 specifically identical ; the same author also states that Phillips' 

 species Pecopteris ligata 3 is identical with Laccopteris poli/podioides. 



FIG. 9. ? Laccopteris polypodioidcs. From a specimen in the Whitby 

 Museum. (Nat. size.) 



The specimen figured by Phillips (in the York Museum) as 

 Pecopteris caspitosa, and redrawn in Text -fig. 8, is undoubtedly 

 a badly preserved fragment of a leaf of -Laccopteris polypodioides ; 4 

 the characteristic habit of the frond is clearly shown, and in 

 some of the pinnules there are distinct traces of son. 



The drawing reproduced in Text-figure 9 was made from

* The type-specimen of this species is in the York Museum. 



8 The type- specimen is said by Nathorst to be in the Oxford Museum.
