| Summary: | Leucascus leptoraphis (Jenkin, 1908) Diagnosis: Cortical membrane with tripods. Atrial skeleton composed of triactines and tetractines with cylindrical actines. Tetractines are very rare. Synonymies: Leucandra primigenia var. leptoraphis: Jenkin 1908: 14; Leucetta leptoraphis: Burton 1929: 404; Gappa & Landoni 2005: 219. Type material: BMNH 1907.8.6.65 (Holotype, McMurdo Bay, Antarctica; Discovery Antarctic Expedition). Type locality: McMurdo Bay, Antarctica. Additional analysed material: ZMAPOR 13265 (Turtle Rock, McMurdo Sound, Antarctica; coll. B. Baker; 1997). Description: There is no information about the colour of the holotype in vivo, but the specimen from the ZMA was white. After fixation, both specimens became beige (Figure 5 A). The cormus is digitiform and formed by tightly anastomosed tubes covered by a smooth and thin membrane. The consistency is soft. Only a fragment of the holotype was analysed, but the specimen from the ZMA measures 9.5 x 5.5 x 2.0 cm (Figure 5 A).
