Small fragments of this delicate bryozoan occurring in the Bowden horizon of 
Santo Do min go are quite sufficient for the determination of the species in the 
American Miocene. The dimensions of the opesium are not equal on the four 
sides, one of which is often larger than the others. The authors are not in accord 
as to the name which should be given to this species. We have adopted that of 
Busk. The species is discussed on page 196 of our monograph on North American 
Early Tertiary Bryozoa, where a more detailed bibliography is given the above 
references being additional ones. 
Occurrence .—Lower Miocene (Bowden horizon): Cercado de Mao, Santo 
Domingo (rare). 
Geological distribution .—Vicksburgian of Mississippi; Lutetian of the environs 
of Paris (Canu); Helvetian of Egypt (Canu); Miocene of Australia (Waters). 
Plesiotypes. —Cat. No. 68471, U.S.N.M.
