Small fragments of this delicate bryozoan occurring in the Bowden horizon of 

 Santo Dommgo 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 dL^tribution. —Yicksburgmn of Mississippi; Lutetian of the environs 

 of Paris (Canu); Helvetian of Egypt (Canu); Miocene of Australia (Waters).
