Reference List of South African Non-marine Mollusca. 61 



have wrongly figured, prior to their description, under one of the 

 older names. In giving all these localities, however, it is my hope 

 that future collectors, on finding a certain shell in a certain neigh- 

 bourhood, will at least have some guide as to the known species 

 with which their specimens may be compared. 



No single map is yet published which includes all the localities 

 mentioned, but to simplify matters as far as possible I have given 

 the province in which each is situated, and subdivided the larger or 

 more intricate districts. Thus, German South-West Africa is divided 

 into Ovampoland (north), Damaraland (or Hereroland) (central), and 

 Great Namaland (south). Little Namaland is in the Cape of Good 

 Hope Province, just south of the mouth of the Orange, and Griqua- 

 land West is that portion of the colony north of the same river. 

 Cape Peninsula, where specially mentioned, refers to the small, but 

 conchologically rich, district between Cape Town and Cape Point. 



British Bechuanaland, on the north, is divided from Bechuana- 

 land by a line nearly following the direction of the Molopo Eiver. 

 Lorenzo Marques represents the whole Portuguese territory in East 

 Africa south of the Zambesi, as distinct from Mozambique to its 

 north ; while the Northern Transvaal comprises the district north of 

 Pretoria. 



An effort has been made to state where the type of each species is 

 preserved, and through the kindness of the custodians of the collec- 

 tions mentioned, I have been able to locate about nine-tenths of the 

 total number. In cases where the type cannot be traced or was 

 never specified, the whereabouts of original specimens has, when 

 possible, been given. 



For the information of local students, the letters S.A.M. are affixed 

 to the names of species contained in the collection of the South 

 African Museum. I may add that the magnificent Burnup Collec- 

 tion is exhibited in the Natal Government Museum, Pietermaritz- 

 burg, while there are good collections of non-marine rnollusca at 

 Grahamstown and Port Elizabeth, and a smaller one at Kimberley. 



It only remains for me to express my most grateful thanks to the 

 many kind friends who have been ever ready to assist me in the 

 many difficulties which have cropped up in the course of even 

 the present unassuming work. It is almost impossible to mention 

 all by name, and I must therefore confine myself on this page to 

 acknowledging my extreme indebtedness to Messrs. J. H. Ponsonby 

 and H. C. Burnup for an enormous amount of invaluable help and 

 advice, to which are due, in great measure, any merits which may 

 eventually be found in the ensuing pages.
