leaf-impressioDS of Glossopteris, although the specimens are 

 fragmentary and badly preserved. Fronds of Glossopteris indica, 

 Schimp., appear to be frequent in this locality. 



Other specimens from Pumpi Gorge, Mount Waller area, near 

 Lake Nyasa, which are all very poorly preserved, show fragments of 

 Glossop <ms-fronds and leaves somewhat resembling those known 

 as NoeggeratJiiopsis, but are too imperfect to be determined. 



The collection, as a whole, is interesting, as confirming the 

 occurrence of the species of Glossopteris previously recorded from 

 Portuguese East Africa by Potonie, and as adding to our knowledge 

 of the Glossopteris Mora as there developed. The addition of Glosso- 

 pteris retifera, Feist., to the list is of interest, for this species has 

 already been recorded from South Africa as well as from India. The 

 specimens of Schizoneura appear to be much more perfect than 

 those named by Potonie, and are almost certainly identical with 

 Sch. gondivanensis, Feist., and not Sch. meriani, with which species 

 Potonie compared his fragmentary examples. Among other new 

 additions are possibly Glossopteris ampla, Dana, and specimens 

 which may be compared with Vertebraria and Nceggerathiopsis. 



Appendix II. — Notes on some Fossil non-Marine Mollusc a and a 

 Bivalved Crustacean (Estheriella) from Nyas aland. 1 By

[Plates XVIII & XIX pars.] 



The specimens described in these notes have been collected by 

 Messrs. A. P. Andrew & T. E. G. Bailey in the north-western area 

 of Nyasaland, during a mineral survey carried out between the years 

 1906 and 1908, under the auspices of the Imperial Institute, the 

 authorities of which have kindly presented them to the Geological 

 Department of the British Museum (NaturalHistory). They consist 

 of Quaternary gastropoda and Palaeozoic pelecypoda, accompanied 

 by Estheriella, all of which exhibit non-marine characters. 



Quaternary Gastropoda. 2 



The Quaternary gastropoda include both freshwater and terrestrial 

 forms belonging to the recent fauna of Lake Nyasa and its 

 surrounding shores. Generally speaking, these specimens are of 

 fresh appearance and well preserved, frequently showing remnants 

 of coloration and periostracum — a condition which more particularly 

 applies to the land-shells. The freshwater shells comprise the 

 genera Viviparus and Lanistes, the former having been obtained 

 from deposits at Chiwondo on Lake Nyasa, at an elevation of 20 feet
