, 1) did not notice the male lobe on the antennulae; 2) mentioned the presence of the lacinia mobilis on the left mandible and its absence of the right mandible (p. 737); 3) it was also the aspect of the mandibular palp illustration that did not show the width of the segment 2; 4) the maxilla 2 was mistakenly illustrated as 3-segmented with rather short segment 2, and the aspect did not clearly show the width of the segments. The presence or absence of the articulation on the antennal scale is a common intraspecific variation in different groups of mysids.
