Distribution. Chile. Callyspongia fusifera (Thiele) (Plate LII, fig. i; Figs. 15, 16). Chalina fusifera, Thiele, 1905, p. 476, figs. 15, 32, 95. Occurrence. St. WS 77: Falkland Islands, 110-113 ™-'^ St. WS 86: Falkland Islands, 157-147 m. Remarks. The specimen assigned to this species is palmo-digitate (see Plate LII, fig. i) and comparison of the figure given with that given for the holotype (Thiele, loc. cit., fig. 15) shows that the two specimens have a similar appearance although the shape.
