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.
