three setae. Mandible rather stout, palp 2-jointed, last joint small with 

 4 terminal seta?. 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 3-jointed ; outer branch the longest, furnished with stronger 

 spines and setse than the inner. Fifth pair of feet with the basal joint 

 much dilated, and bearing six setse on its truncated extremity ; second joint 

 small, with five setae. Caudal segments short and broad ; inner tail setae 

 longer than abdomen; outer about one-fourth shorter than inner. Length, 

 Jq of an inch.

 Genus Merope, n. gen. 



Body slender, elongated, posterior margins of the segments fringed with 

 fine teeth ; abdomen only slightly narrower than thorax. Anterior antennae 

 short, few-jointed. Posterior antennas 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 3-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 setae. 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. PI. 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 antennas 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 setae. 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 setae, the
