Fam. 18. Metidae, 



,-*. Body compart, tapering behind, with the se^im-nts closely 

 crowded together, the 1st one of very large size. Both pairs of antennae coarselj 

 built, tin- anterior ones with the basal joint very large, the posterior ones without 

 any outer rainus. Oral parts very small and closely crowded together, exhibiting 

 a rather anomalous structure. 1st pair of le^s differing conspicuously in structure 

 from the 3 succeeding ones and very coarsely built. Last pair of legs in both 

 sexes imperfectly developed. A single ovisac present in female. 



li'< murk*. This family is established to include the peculiar genii- M> //- 

 of Philippi (= llyopsyllus Brady), which differs in several respects materially from 

 all other known Harpacticoida. 



Gen. 8'2. Metis, Plnlippi. 1843. 



Syu : llyopsyllus^ Brady. 



r ( 'lui I'ncl/'i '*. Body short and stout, gibbous, somewhat resembling 

 that in the genus ]Yentir<>tl'i<i. Cephalic segment very large and tumid, produced 

 in front to a detlexed rostral projection. Urosorae short, tapered, with the genital 

 segment in female imperfectly subdivided. Caudal raini short, truncated at the 

 tip, with the apical seta? rather strong. Eye well developed. Anterior antenna- 

 6-articulate, 2nd joint [firmly connected with the 1st, and produced at the end 

 anteriorly to a hood-like projection: those in male distinctly hinged. Posterior 

 antenna? with the proximal joint subdivided, distal joint armed with strong cla\\- 

 like spines. Ural parts densely crowded and together forming an obtuse cone 

 carrying on each side a bisetose appendage (mandibular palpi and behind a narrow 

 median piece bifurcate at the end (posterior maxillipeds). 1st pair of h-^s \er\ 

 strongly built and armed with claw-like spines, outer rainus .'{-articulate, inner 

 shorter and Inarticulate. The .'{ succeeding pairs of normal structure, with both 

 rami .'J-artinilate. | >:i st pair of le<^ extremely -mall ai d rudinieii'ai \ of nt 



shape in the two s,.\,. s . 



/i> ni'ifk*.- This mentis \\as established by 1'hilippi a- early as in the 

 year 184.'-}, but was not recn^nised by Brady, who describes it under another 

 name, vix.. llyopsyllus. Brady refers the genus to his sub-family Harpacticina
