Supplied with water, the barwicki exhibited the euglenoid movement seen before, trailing the paired posterior suckers (which were quite distinct and each separately pedunculate), behind the body with the adhesive surfaces posteriorly directed. This was observed previously but the note was overlooked in the preparation of the original account where it is suggested that these suckers might actually be only a single adhesive organ, an impression gained from the sectioned individual. The Ulmarra specimens were incapable of swimming. With the water level lowered in the jar, they utilized and moved across the surface film in the typical 'planarian' manner, giving evidence that they are externally ciliated, a point which could not be established previously. Also, with these specimens there was no difficulty in establishing the presence of an accessory ciliary feeding mechanism. With the body raised in the feeding posture, a definite flow of water in beneath the anterior end of the preocular region was clearly seen. Early in February, 1970, Mr. Cann supplied me with bdellasimilid egg capsules taken from Elseya dentata captured in the Raglan River west of Gladstone, Queensland, by Mr. R. Weigand of Mount Larcom. The location is freshwater excepting in the highest Figure 1.—Bdellasimilid egg capsules from Elseya dentata, Raglan River, Queensland. A, B, C, complete capsules. D. Capsule after eclosion. E.
