This })r()jection extends forward for about iialf its lengtli and then upward, the change in direction being- gradual. Eyes large and composed of ten rows of ocelli. Two small tubercles are situated between the eyes, and in the middle of the head and back of these is an arc-shaped depression. The tirst antenna reaches the posterior margin of the head; its flagellum is composed of six articles. The second antenna extends to the posterior margin of the third thoracic segment; its tiagellum is composed of fifteen articles. The thoracic segments are subequal in length. The epimera are long" and narrow, with very acute posterior angles. The tirst seg-ment of the abdomen is almost en- tirely concealed l)y the last thoracic segment. The tifth is likewise covered at the sides by the fourth segment. The last abdominal seg-- ment is triangular in sliape with a rounded post(M'ior margin. Tiie outer branch of tlie uropods is \erv broad an<l oar-shaped, with a rounded extremity. The inner branch is long and slender, of equal breadth thi'oughout its length and rounded on its posterior margin. The inner branch is the longer one. Both are fringed with hairs. In the prehensile legs of this spe- cies the basis presents a row of tubercles on the superior margin. There are two spines on the propodus, one on the carpus, and two on the menis.
