Remarks. The relationship between B. alata and

B. pseudobeyrichi was discussed by Drooger

(1953), Blow (1959), Belford (1966), and others,

and we conclude they are distinct species. This species also resembles Bolivina barbata Phleger and Parker (1951) , but is differentiated by its fewer chambers and less rapid growth rate as pointed out by Asano (1958).

Occurrence. Rare in the Onogoshi, Yonahama,

and Minebari formations.
