three sete. Mandible rather stout, palp 2-jointed, last joint small with 
4 terminal sete. Anterior foot-jaw terminating in two rather feeble parallel 
claws. Posterior foot-jaw 2-jointed, terminated by a long, narrow, curved 
claw. Inner branch of first feet with a long slender basal joint, with 
a few comb-like spines at the extremity of its outer margin, second and 
third joints coalescent, short, terminated by a long, straight, slender 
claw ; outer branch with a strong spine on the basal, and four on the 
terminal joint. Three following pairs of feet somewhat similar, with both 
branches 8-jointed; outer branch the longest, furnished with stronger 
spines and sete than the inner. Fifth pair of feet with the basal joint 
much dilated, and bearing six sete on its truncated extremity ; second joint 
small, with five sete. Caudal segments short and broad; inner tail sete 
longer than abdomen; outer about one-fourth shorter than inner. Length, 
sp of an inch. 
Hab. Otago Harbour, dredged in 7 fathoms among kelp. 
Genus Merope, n. gen. 
Body slender, elongated, posterior margins of the segments fringed with 
fine teeth ; abdomen only slightly narrower than thorax. Anterior antenne 
short, few-jointed. Posterior antenne; without a secondary branch. Mouth 
organs(?). Anterior foot-jaws small, with several digitiform processes; pos- 
terior pair forming a slender clawed hand. First pair of feet with both 
branches 8-jointed; middle joint of inner branch very long, terminal joint 
bearing two slender claws; next three pairs with the inner branch formed 
of one joint, bearing two slender sete. Fifth pair as long as preceding, 2- 
jointed. 
This genus approaches very near Cletodes (Brady), but differs in the 
structure of all the swimming legs. I advance it only provisionally how- 
ever, as it has been founded on the examination of a single specimen. 
1. Merope hamata, n. sp. Pl. X., figs. 22-27. 
Body about five times as long as broad, much constricted between each 
segment. First segment (cephalo-thoracic) about three times as long as 
succeeding ones, front almost truncate, posterior margins produced into 
hook-like wings. Anterior antennæ 6-jointed, rather stout, not so long as 
first segment of body, sparingly setose, second joint longest and stoutest ; 
posterior pair rather long and slender. Inner branch of first pair of feet, 
with the basal joint minute, middle joint very long and unarmed, terminal 
short and slender; outer branch only about one-third as long as inner, 
joints subequal, last bearing five geniculate sete. Outer branch of next 
three pairs normal, inner very short in second pair, about twice as long in 
fourth. Fifth pair strongly curved, the basal joint bearing two branches, 
one normal, foliaceous, bearing about 6 marginal and terminal sete, the
