Seen from above, L. murcena (fig. 16) with its compressed tail looks therefore rather different by the side of the round-tailed L. flagellicanda (fig. 30). The difference is most appa- rent indeed, if the animals are viewed from the side: in L. uuiycena (fig. 15) the tail displays a gradual decrease in height, whereas in L. flagellicaiida (fig. 29) the tail becomes directly remarkably low, as the lower edge immediately behind the anus rises upwards with a rapid slope; by its specialh- slender, whip-like tail, L. flagellicauda stands on the whole quite isolated amongst the.
