what exists of these is more slender than the superior. 
The first pair of legs have the hands quadrate, the 
palm slightly convex, oblique, armed with a few small 
hairs. The second pair are not so large as the first, 
having the hand long and narrow,* the palm very 
oblique, and imperfectly defined. The rest of the 
animal exhibits no remarkable features, except in the 
shortness of the last or single-branched caudal append- 
age, which does not reach beyond the extremity of the 
preceding pair, and scarcely beyond that of the central 
tail -piece which is rather narrow. 
The only specimen that we have seen of this species 
was procured by the Rev. H. R. Hogan from a pump at 
Ringwood. 
* Our enlarged fig. i represents the form of the second pair of hands 
more correctly than the figure of the entire animal.
