rises on the Anglo- Portuguese border and reaches the Zambezi just 

 above Sinjal (fig. 8, p. 216), Lower Shire area. Several fragments 

 of fronds of Glossopteris occur. Some of these appear to be 

 rather small leaves of Glossopteris indica, 1 Schimper, with narrow 

 elongated meshes. The fronds vary greatly in size, small leaves 

 predominating. Some of them closely resemble the figure of 

 G. indica, Schimper, from India, given by Feistmantel 2 on 

 pi. xxxviii a, fig. 4, of his ' Lower Gondwaua Flora '. Other fronds 

 of still smaller dimensions may be compared with pi. xxxivA, 

 fig. 2, of Feistmantel's memoir. Such specimens are difficult to 

 identify specifically, and possibly are only young immature fronds 

 belonging to one of the commoner species, such as G. indiea, 

 Schimper, or G. brovmiana, Brongn. On the other hand, some 

 examples seem to be identical with Glossopteris retifera, Feist. ; and 

 possibly G. angustifolia, Brongn. is represented in the collection. 

 A specimen containing scale-leaves of Glossopteris 2 also occurs. 



In the same locality, associated with fronds of Glossopteris, leaf- 

 segments and stems of a Scliizoneura occur which appear to be closely 

 similar to, if indeed they are not identical with, the Scliizoneura 

 gondwanensis, Feist./ of the Indian Gondwana beds. Scliizoneura is 

 a typical member of the Glossopteris Flora. The South African 

 species Sell, africana, Feist., 5 with which these new specimens may 

 be also compared, has rather narrow sheath-segments, whereas those 

 of Mr. Andrew's examples are very large and broad, in one case 

 the breadth being 4 centimetres. An example of a stem-cast also 

 occurs, showing a node. 



Among the better-preserved specimens are those from Nkombedzi, 

 Pwadze, in the north of the Lower Shire area. Several species of 

 Glossopteris appear to occur here in the Middle Shale Group, both 

 6r. browniana, Brongn., and G. indica, Schimp.,as well as scale-fronds 

 of Glossopteris, being recognized. A large broad frond may be 

 compared with G. ampla, Dana, and leaves of the narrow, linear 

 type with G. angustifolia, Brongn. A very large and broad Verte- 

 braria-like specimen was also collected from this locality, though 

 some little doubt exists as to whether it is a true Vertebraria, 

 since it does not correspond very closely with V. indica, Royle. It 

 may be compared, however, with the figures of the specimens from 

 Portuguese East Africa attributed to this genus by Potonie. 0, Two 

 pieces of petrified wood were also collected from the uppermost 

 shales at Pwadze, but it is doubtful whether they can be identified. 



At Namalundo, 7 north of Zimbawe, brown shales occur, full of
