Siberia; Fhyllotlieca socolowskii, Eicliw., and F. slschuroicshii, Sclimalli., 
described by the same author from the Kusnezk basin ; Fhyllothcca striata, 
Sclimalli,, described by Prof. Schmalhausen, from tlic Jurassic beds of the 
Petschora country ; Fhyllothcca panel folio, Sclimalli., Fhyllothcca stellfcra, 
Sclimalli., and P. equisetitoides, Sclimalli., described by the same author (too. 
cit., 1870) from Jurassic beds on the lower Tunguska Elver, North Siberia. 
(d) Italy . — Prom the Jurassic beds in Northern Italy two species of 
Fhyllothcca were described by Par on dc Zigno — Fhyllothcca JBrongniar liana, 
Zigno, and Fhyllothcca equisetiformis , Zigno. 
(e) England . — No true Fhyllothcca (I mean no leaved specimen) has 
hitherto been described from England, and mention of this country is only 
made because the doubtful Equisetuni laterals, Pliill., is now placed with 
Fhyllothcca (sec Heer, 1876, loc. cit., and Zittel, loc. cit., 1SS0).

Ohs . — This species appears to occur under various forms ; I myself 
figure various specimens. The stem is articulated ; in the joints there are 
sheaths which are striated, and which at the upper margin run out into 
leaflets ; these leaflets arc narrowly elongate and generally somewhat reflected. 
The stem is besides simple or branched ; this, I think, may depend on what 
part of the plant is preserved, at what state of maturity, and so on. Our 
El. XIY, Eig. 1, shows a nice branched specimen from Newcastle, where the 
sheaths are very well seen, but the leaflets appear to be broken away ; but 
PI. XIY, Eigs. 2, 3, show single sheaths where the leaflets are well seen, 
especially Eig. 3, which must be of a very powerful specimen, also from New- 
castle. PI. XIY, Eig. 5, is a specimen of a stem occurring together with 
Fhyllothcca australis , and I believe it may belong to the same species.
