Form robnst. Carapace much wider tlian pleon, not 

 covering all thc thoracic segments; deeply emarginate on 

 its posterior border, anterior border evenly rounded and 

 armed with seven long, slightly depressed, and curved 

 spines, set in the form of a crown. Lateral edges of the 

 carapace bearing at the origin of the thoracic part a sliort 

 stont and bhmt s])ine. Fyes large, reaching to the end 

 of the second Joint of the antennuiar pednncle, their peduncles 

 Short, snbtriangnlar in horizontal section. Colour of visual 

 part orange brown after preservation. Antennuiar peduncle 

 about one-quarter the length of the carapace; last Joint as 

 long as the preceding two, much stouter and thicker than 

 either of the otliers. Antennal peduncle more slender 

 than the antennuiar peduncle, and in dorsal view completely 

 hidden by the latter. Antennae devoid of scale but armed 

 on the basal Joint with a long spine wliich reaches neariy 

 to the centre of the last Joint of the peduncle. Mandible 

 very strong, palp three-jointed, basal Joint the longest, stout, 

 armed on the imier edge with strong setae, a fascicule of 

 which also occurs on the imier distal angle of the Joint; 

 next Joint smaller and more slender than the first Joint, 

 feebly armed with setae; last Joint longer than the second 

 but shorter than the first, robust, and strongly armed with 

 numerous setae on the inner edge, which setae are densely 

 plumose. Tliere is one long and strong seta at the tip of 

 Joint of the palp. Cutting edge not equally developed on both sides,
