GreNus 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.
