Description. — Carapace as viewed above broadly ovoid, taper- 

 ing anteriorly to pointed rostrum, thick, surface covered with 

 more or less conspicuous large wide-set tubercles between which 

 a number of smaller inconspicuous ones, and on anterior lateral 

 region tubercles assuming a more or less longer or conic appear- 

 ance. Posterior edge of carapace rather evenly rounded. Upper 

 surface of carapace all more or less velvety, though along an- 

 terior edges becoming more conspicuously villose. Body in 

 lateral profile nearly evenly ovoid, becomes somewhat attenuated 

 anteriorly, and deepest part about three-fifths width of carapace. 

 Eye-socket little developed, rounded, with well-developed supra- 

 orbital tubercle, also a postorbital and infra-preorbital. On each 

 side of carapace seven well-developed conic tubercles. Eye small, 

 rounded convexly at ends, and stalks short, mobile, and bases 

 little constricted. Rostrum conspicuous, bifid at tip where curved 

 slightly inferiorly. First antennse larger, inferior below rostrum, 

 below which they also fold and are largely concealed, only being 

 separated by low deep-set partition. Basal joint of first antennae 

 well developed, organ ends in slender flagellum and tuft of 

 bristles, and strongly bent upwards to form swollen distal articu-
