8. Cymothoa caraibica, n. sp. 



Diagn. Corpiis convexum, subparallelum, ter fere longius, quam latius. 



Capnt immersum, leviter convexum, pauUo latius quam longius. 

 fronte rotundata in medio procumbente. 



OcuU manifesti, triangulares. 



Antennce sub capite non celataj. Antennas primi paris iis secundi 

 paris longiores, marginem anteriorem segmenti primi pereii vix attin- 

 gentes. 



Processus segmenti primi pereii mediocres, caput dimidio ptene 

 longitudinls sequantes. Segmentum quintum et sextum aliis latiora. 

 Segmentum primum aliis longius. 



Epimera segmenti secundi et tertii latera segmentorum explentia. 



Pedes pe7'eii parium quattuor ultimorum valde carinati, carinis 

 angulate productis. Pedes septimi paris longissimi, femoribus longis. 



Pleo7i breve, latum, segmento primo fere toto obtecto. 



Ums pleon longitudine ajquans, late rotundatus, duplo latior 

 quam longior. 



Pedes uri mediocres, ramus interiör exteriore longior. 



The hody is convex, almost liaear, nearly thrice longer 

 than.broad (41: 15). 



The liead is immersed, feebly convex, a little broader than 

 long (4 : 3) ; the front is roiinded bent downwards in the 

 middle. 



The eyes are distinct, triangulär. 



The antennce are not concealed beneath the head. The 

 first pair of antennse are longer than the second, scarcely 

 reaching to the anterior margin of the first pereional seg- 

 ment. 



The processes of the first pair of the pereion are scarcely 

 as long as half of the head. The fifth and sixth segments 

 are the broadest. The first segment is the lono-est. 



The eimnerals of the second and third segments occupy 

 the whole length of the segments. 



The four last pairs of pereiopoda are strongly carinated, 

 the carinae produced into strong angles. The seventh pair 

 are a little longer than the preceding; its femora are much 

 longer than broad. 



The pleon is short and broad; the first segment is almost 

 totally concealed.
