Fig. 30 Edentulina affinis: Boettger 1913: 349, pl. 15, fig. 8 (Kipatimu, eastern Tanzania; 31.5×15.0 mm).
A common East African species, with a general distribution from Kenya to Mozambique. Found at ten stations inland and two stations on Cabo Delgado. The convexity of the whorls significantly varies amongst the shells from Mozambique and most of the shells do not have whorls “flatter” than in Comorian E. ovoidea (Bruguière, 1789), as stated in the original description of affinis.
