24 MR. E. A. NEWELL ARBER ON [Feb. 1909, 



In the same year Prof. Zeiller 1 contributed a note to tbe Paris 

 Academy on the plants collected by Mr. Brady from the Dover 

 Boring. Some of these specimens are now in the Geological 

 Department of the British Museum (Xatural History). 2 



The following species were obtained : — 



At a depth of 1894 feet. 



Cf. Mariopleris sphenopteroides 

 (Lesq.). 



Neuropteris ScJieuchzeri, Hoffm. 

 Neuropteris rarinervis, Bunb. 



At a depth of 1900 feet. 

 Neuropteris ScJieuchzeri, Hoffm. 

 Neuropteris rarinervis, Bunb. 

 Neuropteris tenuifolia, (Schloth.). 

 Cycloptcris sp. 



At a depth of 2038 feet. 



Neuropteris ScJieucJizeri, Hoffm. i Stiff maria ficoides (Sternb.). 



Lepidodendron lycopodioides (Sternb.). | 



I will discuss the conclusions which Prof. Zeiller draws as to 

 the horizon at a later stage in this paper. 



II. Description or the Specimens. 



In the following descriptions, only a few, typical references to 

 the literature are given. 



Equisetales. 



Calamites, Suckow, 1784. 

 Acta Acad. Elect. Theod. Palat. vol. v, p. 355. 



Calamites cf. C. cisti, Brongn. 



1828. Calamites Cistii, Brongniart, 'Hist. Veget. Foss.' p. 129, pi. xx. 

 1886-88. Calamites Cisti, Zeiller, ' Flore Foss. Bass. Houill. Valenciennes,' p. 342 & 

 pi. lvi, figs. 1-2. 



Waldershare Series at 1925 feet. 



Fragments of pith-casts of Calamites are fairly frequent in the 

 higher part of the Waldershare Series ; but, as one would expect 

 from a core with a maximum diameter of only 3 to 4 inches, they 

 are usually too imperfect for determination. In the case of one 

 specimen however, where a node is seen, as well as part of a fairly 

 long internode, the size and shape of the infranodal scars suggest a 

 comparison with C. cisti.
