Remarks. This is one of the more commonly found large benthic foraminifera in shallow to bathyal seas off Japanese Islands in the southwest. It shows a wide range of variation in the acuteness of the periphery and test convexity. Papp and Schmid

(1985) reillustrated d’Orbigny’s (1846) specimens of Rotalina Kalembergensis , Rotalina Haidingerii ,

and Rotalina Dutemplei , and concluded that H.

dutemplei was a senior synonym.

Occurrence. Abundant in the Oura and Onogoshi formations, sporadic in the Yonahama and Minebari formations.
