plants from the Devonian rocks 91 
In the following year the most important paper which has yet 
been published on the Devonian plant fossils of Devon appeared 
from the pen of Townsend Hall*. He recorded Sigillaria sp. 
from Top Orchard quarry, Calamites sp. from Frankmarsh quarry, 
and Sternbergia sp. from Croyde,—all from the Pilton beds. We 
have not been able to trace these specimens. There is one from 
_the locality first mentioned above in the Atheneum, Barnstaple, 
but if this is the specimen in question, it is quite indeter- 
minable. 
In addition to previous records, the following important deter- 
minations were made from Sloly quarry : 
Adiantites hibernicus Forbes, 
Knorria sp., 
Sphenopteris sp. 
Knorria sp. is also recorded from Marwood, but no plants were 
known to Townsend Hall from Baggy Point, with the exception 
of “doubtful species.” 
Ktheridge+, in his important memoir on the Devonian of 
North Devon, enumerates the same determinations, and records 
Adiantites hibernicus Forbes from both the Baggy and Pilton 
beds. 
Townsend Hall’s collection appears to be preserved partly im 
the British Museum (Nat. Hist.) and partly in the museum of the 
Atheneum, Barnstaple. One of us has carefully examined these 
fossils more than once, but has been unable to find any speci- 
men of Archwopteris hibernica (Forb.) among them. We may 
add that we have never seen any example of this plant which 
there was any reason to suspect of having been derived from 
Devonshire rocks. Thus this record is best regarded as “not 
proven.” 
In 1896 Whidborne? recorded Knorria sp., Bernia [? Bornia] sp., 
Rhodea moravica? and Stigmarian roots from the Marwood, Bagg 
and Sloly beds. It is possible that the attribution to Rhodea 
relates to the fossils here referred to Sphenopteridium rigidum 
(Ludw.). ; 
Hicks§ also mentions plant remains in the Hangman Grits at 
Timberscombe, West Somerset, and from the Pickwell Down 
Sandstones, near Barlinch Abbey, in the Exe Valley. These 
specimens however we have been unable to trace.
