Description. — The branches of the first, second, and third degrees are distichously 

 developed, two arising from the opposite sides of each node, and all seem to lie in the 

 same plane. 



The stem (?) attains a thickness of 0'5 cm. or more, with internodes 375 cm. long, 

 striated longitudinally. Branches of first order are about 2 mm. thick, with the basal 

 internodes about 1 cm. long ; branchlets of the second order very slender, with lower 

 internodes about 0'5 cm. long. 



Leaves whorled, those on the stem upright or adpressed, and probably united to 

 each other by their bases. Leaves on branches and branchlets verticillate, spreading, 

 very small, about 2 to 2'50 mm. long, lanceolate, widest slightly above the middle, 

 and as many as fourteen may enter into the formation of a whorl on the larger 

 branchlets, but on the smaller ones the whorls are formed of a much less number 

 of leaves. 



Cones small, oblong, about 0'5 cm. long, borne on the ultimate branchlets and 

 probably in whorls. Internal organisation unknown. 



Remarks. — The collection contains three small examples of Anmdaria spicata 

 Gutbier sp., which were found at Cooper's Mill section. The fossils are of a rich brown 

 colour on a buff shale, which makes it very difficult to photograph them ; but two of 

 the specimens are given on PI. II, figs. 6 and 7. 



The plants are much broken up, but show a few branchlets, either isolated or 

 springing in pairs from the nodes of a larger branch. The largest leaves on these 

 specimens are from about 2 mm. to 2'50 mm. long, lanceolate and sharp-pointed, but 

 it is only in rare cases that they are perfectly preserved. The leaves, however, agree, 

 both in size and form, with the description given by Gutbier, " linear lanzettliche 

 Blattchen," and there can be no doubt as to the specimens belonging to Gutbikr's 

 " Asterophyllites spicata" with which they agree absolutely. They are identical with 

 those figured by Geinitz in Dyas, pi. xxv, figs. 5, 6. The description of the species 

 given here is partly drawn up from the original figures and description of Gutbier. 



Zeiller, in his Bassin houil. et perm, de Brive, unites to this species the 

 Annularia minuta, of which he figures the two specimens originally so named by 

 Brongniart, but which had not previously been figured or described.* This, however, 

 I believe to be specifically distinct from Annularia spicata Gutbier sp. Zeiller 

 further points out that these specimens of Annularia minuta much resemble the 

 Annularia microphylla Sauveur ; t but the Annularia microphylla is a larger species 

 with sickle-shaped leaves, and the leaf-margins are recurved.^ 



According to my view, it is with Annularia galioides L. & H. sp. that Annularia 

 spicata must be compared. 



Though the leaves of Annularia galioides appear to have had a pilose upper
