Description. — Carapace moderately convex and depressed, sur- 

 face rather uneven and dorsal grooves distinct. Contour of 

 carapace generally convex anteriorly, and sides narrowing con- 

 siderably to moderately 'broad posterior edge. Front with five 

 distinct nearly equal similar crests or ifattened spines so arranged 

 as to form convex contour between eyes. Last of median frontal 

 spines elevated to form inner wall of orbit, and separated from 

 outer by posterior slight notch. Anterior lateral edges of cara- 

 pace with five large flattened serratures, pointed, outermost 

 directed slightly outward and more slender than others, which 

 become gradually smaller towards eye and to which they slightly 

 turn. Posterior lateral edges of carapace undulated or double- 

 convex towards median line. Hind edge of carapace with poste- 

 riorly directed slightly convex line. All edges of carapace with 

 fine beading of small uniform close-set tubercles. Upper sur- 

 face of carapace finely granular, and where ridges slope ofi: 

 from anterior lateral marginal serra^ some of granulations a little 

 enlarged. 



O'rbit moderate, rather ovoid, and lower inner edge pro- 

 jects forward similar to serrae along frontal edge medianly, 

 so as to be visible as viewed from above. Eye-stalks moderate, 

 greater than rounded eyes, and outer basal surfaces villose. 

 Antennules robust, two joints of peduncle semi-cylindrical, and 

 subequal. Two attenuated flagella surmount terminal joint, of 

 which upper ends in filament, longer than lower, and with bunch 

 of seitc-e on its lower edge. Upper flagella a little shorter than 

 terminal joint of antennules. Antenuc-e attenuated, slender, when 

 depressed extend to second serra of anterior lateral edge, 

 peduncle short, of two robust joints, of which basal larger.
