PSEUDOPALLENE AUSTRALIS. 
(Plate I., fig. 2.) 
Specific characters :— 
Body with lateral processes widely separated, these and the cephalon armed with stout spurs. 
Limbs armed with rows of prominent tubercles which bear the setae. Propodus with few setae 
dorsally and a proximal group of three or thereabouts. 
Oviger ten-jointed, four terminal joints long and cylindrical. Denticulate spines without lateral 
teeth at base. 
Body rather robust, though more slender than in the last-named species; lateral 
processes widely separated, and but little longer than the trunk is broad. It is 
smooth except for the spurs on the cephalon and lateral processes. These are similar 
to but more upright than those of P. cornigera. The segmentation is distinct. 
The Ocular tubercle is short, stout, rounded at the extremity, and bears four 
large well-developed eyes. It rises just clear of the first pair of lateral processes. 
The Abdomen is of normal proportions, rather ovoid in shape and without setae. 
There is no articulation, and it is directed obliquely upwards. 
The length of the body is 6mm. and its extreme width is 3mm. 
The Proboscis and the Chelifori are as in the preceding species. 
The Ovigers (fig. 2 a) rise just behind the neck, each from a small body-process. 
The first joint is very small and stout, the second equally stout, but much longer; the 
third is more slender, and has the usual oblique termination, but is scarcely as long 
as the two preceding joints; the fourth is nearly as long as the three preceding. 
The fifth is much the longest of the appendage, slender and rather enlarged distally. 
The sixth is quite small, about a quarter the length of the fifth. All these joints bear 
a very few minute setse, all of which have traces of an enlarged base. The four 
terminal joints are long and slender, with very little difference in their length ; the first 
is longest, the next two are subequal, and the last the shortest. All are provided with 
numerous denticulate spines, which occur in a single row (fig. 2 b). They comprise a 
rather conical shaft, surrounded by a flat leaf-like blade with a finely dentate margin. 
There is no trace of the stout basal teeth so characteristic of the preceding species. 
The end of the terminal joint bears two curved spines, which are obviously the same 
denticulate spines worn down. The character of these four terminal joints differs from 
those of the preceding species in their more slender and cylindrical form as well as their 
greater length. 
The Legs extend to a length of 23mm. Of the three coxae the second is quite as 
long as the other two together; the proportions of the three following joints are as 
6 : 5'5 : 5'5 ; the tarsus is very small, the propodus is curved, especially proximally, 
and rather more than one-third the length of the second tibia. The terminal claw is 
very long and slender ; there are no auxiliaries, nor is there any heel. The setae, if 
such they may lie called, are small and delicate. They lie in lines parallel to the 
surface of the joint, and, with very few exceptions, each one occurs on a prominent
