rarely more ellipsoid in shape. (Pigs. 1-2.) Average length O.519 mm, width 0.334 mm. Cuticle smooth. Oral and ventral suckers neary equal in size, 0.048x0.044 mm, and 0.056x0.053 mm, respectively. Oral sucker terminating in a muscular pharynx, oesophagus shorter to longer, averaging 0.039 mm, but this value varying between very wide limits per specimen. Two caeca reaching oral surface of testes. These latter oval, situated para- or more rarely prae- and postacetabularly. Right testis 0.088 x 0.056 mm, left testis 0.088 x 0.061 mm. Prostata complex located intercaecally

, 0.084x0.085 mm. Ovarium oval or slightly lobate, 0.081x0.070 mm, situated medially, or more rarely slightly laterally, between the two testes. Receptaculum seminis appearing caudally from ovarium. Uterus filled with eggs filling posterior half of body, some of its loops whorls extending anteriorad and reaching even ventral sucker. Genital atrium lying within region of prostata complex.

Vitellary glands forming, characteristically of the genus, two follicular groups caudally of testes. Number of follicles 7 and 9, respectively, similarly to 1. linstowi specimens parasitizing bats. Comparing the measurements of L. linstowi specimens collected by the various authors from the small intestine of bats, it can be stated that the data of flukes extracted from the harvest mouse agree with them within the limits of variation (Table I). Por the sake of a more precise comparison, the measurement data of L. linstowi specimens, deriving from the harvest mouse, are given together with those of L, semen and L. antetestes (Table II). The fluke species found in the harvest mouse is indubitably identical with Lecithodendrium linstowi parasitizing bats, a statement convincingly substantiated by the morphology of the worm, the position and dimensions of its organs, as well as the characteristic number of the follicles. Among the other Lecithodendrium species parasitizing small mammals, L. semen (Kirschenblatt, 1941) and L. antetestes Prokopic, 1957, stand nearest to it. The measurement data of L. linstowi specimens found in the harvest mouse agree - within the limits of variation -
