of four, the lower horizontal ridge continued behind with even curve into 

 the hinder vertical ridge, not extending behind to the edge of the carapace; 

 the hind vertical ridge forks into two obtusely diverging branches; the 

 front one does not reach the ridge running backwards from the anterior 

 upper tubercle. Dorsal crest of 2^^ pedigerous segment produced backwards 

 into a large rounded lobe. Dorso-lateral crests of following segments stronger 

 than in C. elegans. Peduncle of uropods more decidedly longer than the 

 rami, endopod not curved at the tip. L. o 5-75 mm, 6 (immature, with no 

 cristiform lobe on 2°*^ pedigerous segment) 5-25 mm.

Pseudorostral lobes short, truncate, not reaching beyond the eyelobe; 

 antero -lateral corner showing 2 teeth, the lower the sharper and more produced. 

 Carapace sharply carinate, with tooth overhanging base of eyelobe, and sharp 

 ridge from near the middle curving downwards and forwards on each side 

 towards but not reaching the antero-lateral corner. First pedigerous segment 

 narrowly exposed dorsally, 2"'^ feebly carinate. Pleon long, rather slender. 

 Eyelobe not longer than broad, occupied by about 9 corneal lenses, with 

 pigment. Antenna 1, 3"^ joint longer than 2'^'^, accessory flagellum minute 

 but distinct. Maxilliped 3, 2^'^ joint angled, longer than rest of limb, distally 

 produced nearly to end of the much produced 4*^. Peraeopod 1 very long, 

 2°<^ joint apart from distal tooth of medial margin little longer than 6*^^ and 

 7^^ combined, 7*^ longer than 5*^ but considerably shorter than 6*^. Peraeopod 

 2 stout, 2"^^ joint longer than rest of limb, in which the 7^^ joint is the longest. 

 Peduncle of uropods sKghtly shorter than the exopod, as long as the endopod, 

 which has about 9 spines on the medial margin, and is distally bare, api- 

 cally acute. L. Q (immature) 4-9 mm, d unknown.

Pseudorostral lobes slightly prominent, eyelobe reaching quite to the tip ; 

 antero-lateral corner acutely produced, not quite level with pseudorostral apices. 

 Carapace granular, with median carina produced into a forward pointing 

 tooth behind the eyelobe, without transverse ridges. First pedigerous segment 

 not exposed, 2»d feebly carinate. Pleon rather long. Peraeopod 1, 2»<^ joint about 

 three-fourths as long as rest of limb, 3^ and 4**^ joints stout, the slender 5*^ 

 and 6*^ equal, 7*^ much shorter than either. Peduncle of uropods considerably 

 longer than the rami, exopod slightly longer than endopod, which has 4 small 

 spines on the serrate medial margin and a long one on the subobtuse apex. 

 L. 9 (immature) 3-2 mm, d unknown.

9 . Pseudorostral lobes short, horizontal, with the long narrow eyelobe 

 projecting in front; antero-lateral tooth not level with the apices. Carapace 

 strongly arched, a little in front of middle encii'cled by a very prominent 

 collar, notched at the centre, its lateral apices turned a little forwards and
