26 EQUISETITES. 



3582. 12-5 cm. long. Average length of internodes 2 cm., 

 breadth 1-2 cm. Mantell Coll. 



3591. Badly preserved and crushed stem, shows four and 

 a half internodes. One branch. Cf. Schenk, Palseontographica, 

 vol. xix. pi. xxiv. fig. 12. Mantell Coll. 



3594. Stem showing three nodes, sheathing leaves, and one 

 branch. Mantell Coll. 



3598. Small piece, with one node and leaf-teeth particularly 

 well shown, also a branch; almost identical with Schenk' s fi.g. 11, 

 pi. xxii. Palseontographica, vol. xix. Mantell Coll. 



3601. This small specimen may be merely a fragment crushed 

 at one end, but possibly it is the apical termination of a branch. 

 The long linear leaf-teeth are distinctly seen and appear to be 

 closely pressed against the apical bud. Cf. JEquisetites MUnsteri, 

 Schimp.' Mantell Coll. 



8383. Internodes about 2-2 cm. long and 2-2 cm. broad. This 

 specimen, also 10,847, 13,399 and others, has shorter internodes 

 than most examples of the species ; the leaves are less clearly seen, 

 but faintly indicated here and there. There is a distinct similarity, 

 as regards the diameter of the stem and the length of internodes, 

 between such specimens as this and the figure of Equisetites 

 Phillipsii, Schimp., given by Schenk,* but I am unable to fix 

 upon any definite characteristic which would warrant the removal 

 of these larger forms to another species. Pounceford. Mantell Coll. 



12,399. Probably the same species. 14"5 cm. long ; leaves 

 not clearly defined. Pounceford. Mantell Coll. 



12,403. Internodes 2-5 cm. in length, 1'8 cm. broad. Im- 

 perfectly preserved. Pounceford. Mantell Coll. 



12,406. 11 '5 cm. long. Impressions in the places of the 

 characteristic leaves. Pounceford. Mantell Coll. 



39,123. 6-5 cm. in length. Crushed and very imperfect. At 

 two of the nodes there are irregular projections, with their 

 surfaces exhibiting a rough warty appearance ; in all probability
