Abstract |
A comparative study of topotypes of Saccoglossus ruber (Tattersall) S. serpentinus (Assheton) and S. cambrensis Brambell & Cole shows that they are conspecific, and ought henceforth all to be designated S. ruber (Tattersall).The following characteristics distinguish S. ruber from all other species of the genus:— 4 to 6 concentric rings of longitudinal fibres in the proboscis, one proboscis pore on left of stalk, proboscis 3 to 7 times the length of the collar, 45 to 95 pairs of branchial pores, 6 to 12 oesophageal pores—2 to 5 rudimentary, 5 histologically distinct regions in the collar and 3 in the oesophagus. Munsell, Ridgway and I.S.C.C.—N.S.B. colour designations for the various regions of the body have been tabulated. |
