Chone murmanica oculata Annenkova, 1952: 153   –154.

Material examined. Type material. Laptev Sea [ ZIRAS 47434, syntype], RV Sadko, Sta. 9, 77° 25.5 ’ N, 115 ° 45.2 ’ E, 62 m, sandy mud, Coll. G. P. Gorbunov.

Additional material. Chone murmanica Lukasch, 1910   [ ZIRAS 38178, Franz-Joseph Land].

Diagnosis. Tube organic, transparent, more or less incrusted by sand and mud. Anterior peristomial ring (apr) exposed beyond collar dorsally ( Fig. 12 View FIGURE 12 A). Ventral margin of collar higher than dorsal ( Fig. 12 View FIGURE 12 B). Lateral margin of collar with a median depression ( Fig. 12 View FIGURE 12 B). Anterior peristomial ring lobe not exposed beyond collar. Peristomial eyespots present. Glandular ridge on chaetiger 2 narrow. Thoracic segments biannulate. Ventral thoracic shields well developed ( Fig. 12 View FIGURE 12 B).

Remarks. According to Annenkova (1952), Chone murmanica oculata   and C. murmanica   have similar shape of the collar, branchiae, chaetae and tube, but they differ because C. m. oculata   has eyespots on peristomium   and despite being bigger, it has less chaetigers. However, C. murmanica   has peristomial eyes (see diagnosis of C. murmanica   above), and re-examination of type material of C. m. oculata   shows additional differences: C. m. oculata   has the lateral margin of collar with a median depression (absent in C. murmanica   ); the anterior peristomail ring is exposed dorsally (not exposed in C. murmanica   ); anterior peristomial ring lobe not exposed beyond collar (bilobed, exposed beyond collar in C. murmanica   ); and the entire length of middorsal collar margins forms a narrow gap (very prominent margins and broad gap in C. murmanica   ). Thus, C. m. oculata   deserves specific status although examination of more materials from the type locality is necessary in order to describe characters from chaetae and uncini, and branchial crown appendages.
