Notr.—As the Holotype is the specimen figured and described by 
Sowerby, and as Brown’s figure is only a copy of Sowerby’s, 
the older author’s figure and description are entitled to be 
considered as the Z: f and Z.d. respectively. Really all 
that Brown did was to change the name, and to alter 
slightly the wording of the description.

NotE.—Nota variety of 2. angulata (acutiplicata) as it lived long before 
it. Besides it probably belongs to quite another genetic 
series. &. subangulata is a multiplicate derivative of FR. 
acuta through R. cynocephala ; R. acutiplicata is more allied 
to the &. concinna group.
