A tablet from the Cuming collection labelled as above bears 3 examples 

 of this species, presumably collected by Plant, as were those on an adjacent 

 tablet, also from the Cuming collection, labelled Natal. 



There is nothing inherently improbable in either this or the following 

 species, both prominent Natal forms, extending up the coast to Delagoa 

 Bay, but neither of them has been collected there since the days of Cuming, 

 and it appears questionable whether his locality is correct, or whether the 

 shells may not rather have become accidentally separated from a parcel 

 from Natal. 



Gulella ivahlbergi (Krauss), 1848. 



1848. Pupa wahlbergi Krs., Siidafr. Moll, p. 80, pi. 5, fig. 5. D.F. 



1898. Ennea transiens Stur., S.A. Moll., p. 19, pi. 1, fig. 4. D.F. 



Hab. L. Marques. Delagoa Bay (Plant, in British Museum). 



The original figures of wahlbergi and transiens only differ by the large 

 palatal tooth appearing, in wahlbergi, to have the upper cusp more pro- 

 minent and nearer the surface than the lower one, whereas in transiens it is 

 accurately represented, as found in this common Natal species. 



However, Dr. Baini Prashad has kindly compared typical examples of 

 transiens with the type of wahlbergi in the Stuttgart Museum, and writes : 

 "The specimens of transiens Stur. do not differ in any way from Krauss' 

 unique type of wahlbergi. The outer lip has the big tooth absolutely 

 identical in specimens of transiens and ivahlbergi, and I can see no difference 

 between the two." 



Under these circumstances it is evident that Krauss' figure is inaccurate, 

 and Sturany's name must be placed in synonymy.

Described from Mumba I., Lake Nyasa (Kirk), this species was recorded 

 by Smith in 1881 from between L. Nyasa and the east coast (Thomson), 

 and in 1899 from Zomba Plateau ; Masuku Plateau ; Nyika Range, and Mt. 

 Chiradzulu, all in Southern Nyasaland.
