Palaeozoic Pelecypoda. 



Under this heading are included a number of natural casts of a 

 small pelecypod shell belonging to Amalitsky's genus Palceomutela, 

 and to the species oblonga of Prof. T. Rupert Jones, which the latter 

 described some years since from specimens collected by the late 

 Prof. H. Drummond at Maramura, west of Karonga on Lake Nyasa, 

 and some 20 or 30 miles south of Nkana, whence the present 

 material was obtained (see pp. 204, 207). The specimens occur 

 in a blackish shale, associated with fish-scales and the remains of 

 EstherieTla. Parts of the same shale are of oolitic structure. 



Palceomutela and its associate Palceanodonta belong to a series of 

 freshwater or lacustrine pelecypods which are distributed through 

 the lower portion of the Karroo System of South Africa, having 

 been recognized at Beaufort, Bedford, GraafT Reinet, Kimberley, 

 in Northern and Southern Rhodesia and North-Western Nyasaland.
