840 CRUSTACEA. 



rings of the body very prominently projecting, giving the thorax a 

 nodose appearance. It differs from the species of Platophium in the 

 first and second pairs of stylets, one branch of which, the inner, is not 

 only longer than the outer, but is lamellar, instead of subcylindrical 

 or sty li form, and the terminal spines or setae are longer, the longest 

 being nearly as long as the branch. 



Cyrtophium orientale. 



Antennae bene pediformes, infra ciliatce; inferior es flagello vix instructce 

 duobus articulis parvulis confedce, articulo precedents (ad normam 

 lmo flagelli) valde oblongo, longiore quam proximus precedens; supe- 

 riores articulis apiealibus 3 subwquis simul sumtis articulum Stium 

 longitudine cequantibus confectce, ciliis prcelongis. Manus 2da crassa, 

 subelliptica, infra fere recta et liirsuta, digito parce breviore quam 

 manus. Pedes 6 postici subwqui, fere nudi. Styli caudales 2di \mi- 

 que apice spinis longis armali, ramo interne- lamellate- et margine in- 

 terne- spimdoso, ramo externo breviore, subterete. 



Antennae pediform, ciliate below ; inferior pair hardly having a fla- 

 gellum, ending in two very small joints, the preceding joint (nor- 

 mally the first of the flagellum), being long styliform, longer than 

 the joint next preceding ; superior antennae with three subequal 

 joints at extremity, which together are as long as the third joint of 

 the antenna; cilias below very long. Hand of second pair quite 

 stout, subelliptical, nearly straight below and hirsute ; finger very 

 nearly as long as hand. Caudal stylets of first and second pairs 

 with very long spines at extremity (one nearly as long as the 

 branch) ; inner branch lamellar, having inner margin spinulous ; 

 outer branch shorter than inner, and subterete.
