Bursaopsis
Bursaopsis conicoides Hada, 1970 (ref. ID; 3544 original paper)
Description; The lorica is simple in form, and is composed of a typical cone with straight side lines. The oral aperture is large and circular, and the distal end is pointed. (ref. ID; 3544)
Comments; The new species is distinguishable from the known forms of Bursaopsis in the conical form of the lorica. Fixed specimens attached to the inside of a lorica were sometimes observed. Because of this fact, the form is apparently an independent new species carrying a simple conical lorica, which is variable in length. (ref. ID; 3544)
Type locality; It was found in the materials obtained from the cold sea of Syowa Station and from the warm sea of South Africa. (ref. ID; 3544)
Measurements; Length 25-65; oral diameter 17-30 um. (ref. ID; 3544)
Bursaopsis ollula Hada, 1970 (ref. ID; 3544 original paper)
Description; The small lorica is ovoid urn-shaped without a collar, and the oral aperture is more or less small. The wall is thin and transparent. (ref. ID; 3544)
Comments; The new species is somewhat similar to B. bursa (Cleve) in outline of the lorica, but it is distinguishable from the latter in form of the lorica having no collar. (ref. ID; 3544)
Type locality; It was observed in the material taken from the cold sea of Syowa Station. (ref. ID; 3544)
Measurements; Length 15-24; breadth 12-25; oral diameter 6-10 um. (ref. ID; 3544)
