Remarks. This species exhibits a wide range of variation in test size, length of apertural neck, and growth rate. It is occasionally difficult to distinguish younger specimens with shorter neck and compact chamber arrangement from E. canariensis , yet E.

vadescens usually has a slender shape. There appear to be intermediate-transitional forms in the growth of elongate apertural neck and uncoiling mode of chambers between the present species and Siphouvigerina ampullacea (Brady) .

Asano’s (1958) data on the bathymetric distribution indicate that this species prefers the lower sublittoral to upper bathyal off southwest Japan where the warm Kuroshio water flows.

Occurrence. Common in the Oura and Onogoshi formations, rare in the Yonahama and Minebari formations.
