the Senonian of Aachen in Rhenish Prussia.* They considered 

 it as possibly a fern of unknown affinities (" Plantae incertae sedis, 

 filicibus affine.s M ) but could find nothing in the existing or fossil 

 floras of the globe which matched it in venation, and they remark 

 on its resemblance to such conifers as Thuja, Thujopsis, and 

 Libocedrus. 



The Swedish arctic expedition of 1 870-1 872 collected the same 

 plant at Kudliset on Disco Island, and Professor Heer described it 

 as a new species of Pecopteris (P. kudlisetensis)^ 



Both the Prussian and Greenland specimens were poorly pre- 

 served ; subsequent collections, however, contained better material 

 which was elaborated by Prof. Heer, who recognized the true 

 identity of the specimens, placing them in the Cupressineae be- 

 cause of their resemblance to Liboccdnis\ 



He corresponded with Dr. Debey to make sure of his identifi- 

 cation, but the latter refused to admit their gymnospermous char- 

 acter, maintaining that certain discoid fungi which were found on 

 some of the specimens were sori which thus established their 

 filicean nature. 



The next we hear of this species is in abundant remains from 

 the upper Raritan clays at South Amboy, N. J., which Dr. New- 

 berry during a European trip in 1888 compared with some of 

 Debey's specimens. In his flora of the Amboy Clays numerous 

 fine specimens are figured § and it is worth mentioning that the 

 abundant and more representative collections from the lower 

 horizons in the Raritan do not show any trace of this species 

 which is so common at South Amboy. 



In 1898 Dr. Hollick records specimens from Block Island and 

 from Staten Island. || 



The write* has collected this species in considerable abund- 

 ance, but in a rather fragmentary condition, from the Cretaceous
