 "Rotalia" ozawai Asano. — Graham and Militante, 1959, Stanford Univ. Publ., 



Geol. Sci., vol. 6, no. 2, p. 100, pi. 15, figs. 6-8. 



This species, described and reported from the Pliocene to Recent 

 of Japan and the Recent of the Philippines, is found in shallow water 

 at Levuka and Viva, Fiji, and at Rotonga. 



Two specimens are illustrated to show the extremes of variability 

 from specimens with pointed chambers ending in spines to those with 

 a nearly entire periphery and no spines. The dorsal surface is nearly 

 flat and the ventral surface convex. The ventral sutures are incised. 

 In most specimens the spines are poorly developed and inconspicuous, 

 and their position has no precise relationship with the sutures that 

 separate the chambers. The aperture is that typical of the genus 

 Pararotalia. Figure lc shows the opening into an earlier chamber, 

 where the two latest chambers have been broken away, and figure 2c 

 shows the normal unbroken condition.

This well-known and widely distributed species is found (but only 

 in the form of its small and delicate subspecies tepida) in many of 

 the shallower samples taken from near islands and atolls.
