Distribution. Recent : West Indies ; Florida ; Abrolhos Banks, Brazil. Fossil : 

 Barbados : Low-level Reefs, Ceres (Jukes-Browne Coll.), near Bridgetown (Franks 

 Coll.) ; High-level Reefs, Castle Grant, 1070 feet (Jukes-Browne Coll.); Spring Estate, 

 St. Andrews ; Two Mile Hill, St. Michael's. San Domingo,Nivaje' Shale ; Jamaica. 



Notes on Synonymy. — The only point requiring notice in the 

 synonymy of this species is in reference to Duncan's species A. grandis 

 and his identification of some specimens as a variety of the common 

 Italian Miocene form, A. crenulata (Blv.). Duncan's type of the 

 former is preserved in the British Museum ; sections of it agree 

 exactly with those of A. siderea from Barbados. The specimen on 

 which he based his record of A. crenulata is a small one, and appears 

 to be only a young form of this species.
