Aulosaccus ijimai ( Schulze, 1899) Suppl. View in CoL Tab. 7.

SYNONYMY: Calycosaccus ijimai Schulze, 1899: 30 ; Aulosaccus pinnularis Okada, 1932: 88 ; Koltun, 1967: 75.

MATERIAL. IORAS 5/2/2045. RV ‘ Akademik Mstislav Keldysh’ – 22, sta. 2304, HOV ‘Mir-2’, Pacific side of the Bering Island, 55°02.6′ N 165°55.2′ E, 509 m. GoogleMaps

DESCRIPTION. BODY. The specimen is 200 mm long, 80 mm in maximal diameter, with walls 10–15 mm thick.

REMARKS. The species is well–known and the precise description of spicules is omitted being presented in the Suppl. Table 7. As in the previously described materials the new specimen has no hypodermal pentactins. Most spicule measurements correspond to those published before ( Schulze, 1899; Okada, 1932; Koltun, 1967). Nevertheless, the absence of the sufficient description of C. ijimai allows attributing it to the A. pinnularis , since newly collected specimens of A. pinnularis demonstrate wide variation of spicule sizes which are often intermediate between A. ijimai and typical A. pinnularis after finding of the new representative which spicule measurements are often intermediate between the previous two species: ‘ ijimai ’ ( Schulze, 1899) and ‘pinularis ’ ( Okada, 1932).
