genus Antigona Schumacher; this group was designated as Cytherea s.s.^ by Dall and given 

 the new generic name Periglypta by Jukes-Browne (op. cit., p. 72). I am, however, of opinion 

 that the group, though well defined, does not merit séparation into a distinct genus or subgenus. 

 The génotype of Antigona is Antigona lamellaris Schumacher. 



A second subgenus represented in the "Siboga" collection is Clatisina Brown ^) — type 

 Antigona [Clatisina) verrucosa (Linn.).
