874 CRUSTACEA. 



longer than base, its joints oblong, and setae very nearly as long 

 as joints, verticillate and rather numerous. Superior antennas 

 half shorter than base of inferior. Four anterior feet quite small ; 

 those of the second pair a little the largest, the hand oblong sub- 

 elliptic, reversed or bent forward, broadly rounded at apex, the 

 minute finger articulated with the margin towards its middle, and 

 lying longitudinally along the joint. Four following feet subequal, 

 claw small. Last six feet not very unequal, setae or spinules short, 

 those of the fifth joint on both margins about equal, and in seventh 

 "or sixth pair of legs about six sets of spinules; first joint of fifth pair 

 oblong, of seventh very broad. Outer branch of first pair of caudal 

 stylets bearing a few spinules.

From moist soil in the bottom of the extinct volcano of Taiamai, 

 New Zealand, twenty miles from the sea, and about the joints of suc- 

 culent plants. 



Length, one-half to two-thirds of an inch. The superior antennae 

 reach to apex of penult joint of base of inferior antennae. The 

 joints of the flagellum of the inferior antennae are rather longer than 

 twice their breadth, and the last of the basal joints — all of which are 

 very slender — is two-thirds the length of the next j)receding. The 

 hands are very small. In the second pair the length is more than 

 twice their breadth, and they are bent forward at right angles with the 

 preceding portion of the leg ; they are naked except some very minute 

 setae on the under side near apex, at a faint emargination, just where 

 the extremity of the finger terminates. The setules of the legs are in 

 pairs, as usual, with one or two additional of smaller size. The tarsi 

 are slender and nearly straight. The tarsus of the fourth pair of legs 

 is much stouter than the others. 



This species is quite similar to the tenuis in the superior antennas, 

 even to the whorl of setae at the apex of the joints. But the superior 

 antennae are very much shorter, and the hands of the second pair are 

 very different.
