 issued frm : A. Scott in Siboga-Expedition, 1909, XIX a. [Plate V, Figs.13-24]. Doutful (perhaps Aetideopsis multiserrata). Female (from Indonesia-Malaysia): 13, habitus (dorsal); 14, forehead (lateral); 15, last thoracic and genital segments (left side); 16, rostrum; 17, A1; 18, A2; 19, Md (biting blade); 20, Mx2; 21, Mxp; 22, P1; 23, P2; 24, P4. Nota: The minor points of difference with the description and figures given by Sars are: the external margins of the rostrum are more concave, and the excavation between the rami is much narrower. A comparison of the North Atlantic specimens from the Faroë Channel with the specimens from the 'Siboga' does not reveaf difference.
