Bubaris antarctica Koltun sp. n. (Figure 21)

TYPE SPECIMEN: No. 11804 in the collection of the Zoological Institute of the Academy of Sciences of the U.S.S.R.

LOCALITY. St. 460.

DIAGNOSIS. Body globular, slightly elongated, with a narrow basal part, up to 5.5 cm high (2.5 cm wide). The body is rigid; surface uneven, covered with tubercles and conules. The dermal membrane is filmlike, easily separated from the body and devoid of skeleton. Color: brown. The basal skeleton is formed of fibers composed of oxeas, which are strongly and irregularly curved, and straight styles; such styles, united in bundles, also form the dermal skeleton and protrude above the super­ficial conules and tubercles.

Spicules. Macroscleres: curved oxeas (often with blunt ends) — 0.500 - 1.300 mm long and 0.021 - 0.050 mm wide; straight styles — 0.980 -2.400 mm long and 0.030 - 0.052 mm wide. No microscleres.

The new species is closely related to B. murrayi Topsent (1913:616).
