Description. — Carapace as viewed from above broadly ovoid, 

 greatest width a little before center in vertical diameter, and 

 latter about three-fourths of horizontal diameter. Dorsal sur- 

 face of carapace smooth and moderately convex. Rostrum as 

 a single median spine directed forward, though much shorter 

 than extended stalked eyes, and on each side of former a shorter 

 and similar spine. Antero-lateral edge of carapace with five 

 strong anteriorly directed equidistant similar spines. Postero- 

 lateral edge of carapace slightly emarginate. Hind edge of 

 carapace broadly convex. Body in profile laterally rather 

 ellipsoid, and greatest depth nearly equals half of vertical diame- 

 ter of carapace. Eye-socket moderate, ellipsoid, inclined down- 

 ward from rostral spine slightly, and enclosed below by long 

 epibranchial spine, latter longer and better developed than any 

 of antero-lateral spines of carapace and inclined anteriorly 

 towards rostral spine. 



Eyes well developed, when erected conspicuous, when de- 

 pressed fit in cavity between base of epibranchial spine and 

 first antero-lateral spine. Eyes somewhat conic, surfaces 

 rounded, and though stalks somewhat swollen sub-basally 

 they become more constricted at base. First antennae rather 

 slended, close before base of eye-stalk, about long as ex- 

 tended eye-stalk, and ends in tapering slender flagellum. Second 

 antennae close together below rostral spine, with long basal joint, 

 bent back so that distal articulation falls within hiatus between
