Macrobiotus virgatus, Murray ? (Plate XVIII. Fig. 28) 

 See description in Canadian Tardigrada, p. 173, and figure (Plate XXI. 



Figs. 55a-55c). 



The Australian form is not fully studied, but it agrees with the type in the 

 important characters of the pharynx and claws. The teeth are straight for three- 

 quarters of their length, then very abruptly bent outwards. There is some individual 

 variation in this respect. The pharynx possesses a minute comma, which is not noted 

 for the type. There are no eyes, while the type has eyes. There are no notes as to 

 the colour of the Australian examples. 



Habitat. Katoomba, in the Blue Mountains, New South Wales. 



Macrobiotus, sp. ? (Plate XVIII. Figs. 32o-32c) 



Description. Large, 450 M in length. Gullet slender ; teeth slender, abruptly bent 

 towards the furca. Pharynx shortly oval, with two rods in each row, and no 

 comma. The first rod is twice as long as the second, and about four times as long as 

 broad. The claws are V's, or more properly U's, united at the base only. The pairs 

 are unequal, and one claw of each pair is longer. The longer claws have two fine 

 supplementary points. Each foot has a prominent boss near the extremity. The skin 

 is finely granular. 



Habitat. Katoomba, Blue Mountains, New South Wales. 



This appears to be a very distinct specieSj but till more specimens are examined, 

 and the eggs found, it is not desirable to name it. Plate figures such bosses on 

 the legs of M. oberhauseri. 



Macrobiotus, sp. ? (Plate XVIII. Figs. 33a-33c) 



A small animal, resembling M. hufelandii in claws and pharynx, yet with several 

 points of difference. 



Description. Very small ; the example studied measured only 120 /m in length. 

 The gullet is wide, and has a very prominent rim on the end in the pharynx. The 

 teeth are strongly curved. The pharynx is shortly oval, and has two rods in each 

 row and no " comma." The rod next the gullet is about three times as long as broad, 

 the second rod about twice as long as broad. The claws are slender, and are united 

 for rather more than half their length. The two claws of each pair are slightly 

 unequal. Eyes are present. 



Habitat. Eumundi, Queensland. 



Although very similar to M. hufelandii, the characters of the pharynx are 01 some 

 value. It would be necessary to find the egg in order to settle the position of the 

 animal.
