GENUS MELAMPUS, de Montfort, 1810. 



(Conch. Syst. ii. p. 319.) 

 ( = Conovulus, Lamarck, 1812, &c.) 



Type of Genus, M. coniformis (Brug.). 



Recent classification of this Genus is somewhat unsatisfactory : 

 species from widely distant localities can, certainly, be placed 

 together in well-marked groups, members of which have of late 

 years been placed in synonymy ; but it appears almost impos- 

 sible that these inoperculate, brackish-water pulmonates can travel 

 such immense distances as, say, from the Sandwich Islands to 

 Natal, and it is in the highest degree unlikely that the union of 

 shells from such localities under the same name can be correct. 



On these grounds I have preferred to retain, as far as possible, 

 names of species described by the older writers from South Africa 

 for specimens recently collected there, although faulty figures and 

 lack of authentic examples render their correct identification by no 

 means certain.
