Seen from above, L. mitrcena (fig. 16) with its compressed tail looks therefore rather different b\- the side of the round-tailed L. Jiagcllicaiida (fig. 30). The difference is most appa- rent indeed, if the animals are viewed from the side: in L. miirceiia (fig. 15) the tail displays a gradual decrease in height, whereas in L. flagellicauda (fig. 29) the tail becomes directly remarkably low, as the lower edge immediately behind the anus rises upwards with a rapid slope; by its special!}- slender, whip-like tail, stands on the whole quite isolated amongst the 0 ?^^i^S8^«J^^!}58^aa^g;:^^^>- gjgars^g-;.
