Eucinetops,^ nov. gen. 



■ Rostrum parvum, bifidum, parum deflexum. Oculi longissimi, mar- 

 gines carapacis multo superantes. Orbitas parvse, basin pedunculi oculo- 

 rum solumque includentes ; angulo externo acuto spiniformi ; margine 

 superiore unifisso, dentibus spinisque destituto. Fossa) antennularise non 

 profunda^, marginibus obtuse rotundatse. Antennarum externarum arti- 

 culus basalis parvus, angulo externo dente uno minuto armatus ; pars 

 mobilis depressa, articulis primo secimdoque perlatis. Epistoma per- 

 breve vel nullum. Maxillipedes externi eis MicippcB vix diversi, sed 

 meri angulo 6xterno prominentiore, angulo interno minus sinuato ; palpo 

 basi turgido ; exognatho antrorsum endognathura superante. 



This genus is allied to Ificippa. It is remarkable for the 

 great length and mobility of its eyes, which may be thrown 

 forward, upward, or even backward over the carapax.

 rounded at the extremities. Lateral margins of the carapax without
