, but, according to the original description, this latter "nearly lacks an oesophagus", while it is present in L.linstowi

. On the other hand, it is rather thoughtprovoking that the oesophagus is very short, only 15/i , in certain L. linstowi exemplars. The figure accompanying KIRSCHENBLATT's original description also showsavery short oesophagus, without any measurement data. It is highly probable that L. se men is identical with L. linstowi

, and in this case its junior synonym. L. antetestes differs from L. linstowi by its essentially greater dimensions. As one of the results of our investigations, the problem of the means of infection of a rodent by a "bat trematode" can be raised justificably. The only acceptable solution is that the same intermediate insect host serves as food for both the harvest mouse and the bats. The bats are presumably infected by capturing the flying specimens of some insect (or insects) with an
