Pseudorostral lobes slightly upturned, apices bluntly rounded, not reacMng 

 beyond eyelobe. Antero-lateral corners in (3 obtuse. Carapace short, surface 

 anteriorly beset with forward directed spiniform points, anterior half with 

 medio-dorsal carina. Pedigerous segment 1 strap-like, 3^ and 4*^ laterally 

 articulated, 3^ to 5ti» faintly showing the three pairs of ridges, dorsal, dorso- 

 lateral, and lateral, better developed on the first 5 pleon segments, on the 

 5th the lateral joining the dorso-lateral at about the middle of the segment. 

 The telsonic segment with some ridges and a dorsal depression is squarely 

 produced between the uropods. Eyelobe narrowly linguiform, slightly expanded 

 at apex, with 2 large but indistinct corneal areas. Antenna 1, 1^*^ and 3^ 

 joints longer than 2'^'^, flagellum of 3 joints, 1^* in c5" dilated at base with brush 

 of sensory filaments; accessory of 2 joints, 1^* dilated, also with brush of 

 shorter filaments. Maxilliped 3, 2"^ joint very much longer than rest of limb, 

 apically produced to denticulate apex of little produced 4*^ joint. Peraeopod 

 1 elongate, 2"^ joint long, but shorter than rest of limb, 7t'i joint long, but 

 shorter than ^^\ Peraeopod 2, with 3^ joint distinct but very short. Exopod 

 of peraeopod 3 slightly smaller than that of two preceding pairs. Pleopods large, 

 rami of 1 *** pair about two-thirds of length of peduncle. Peduncle of uropods 

 much longer than exopod, in which the 1^* joint is subequal to 2^<i of 

 endopod, the 2'^'^ longer than the 1-^* of endopod, which is about once 

 and a half as long as its own 2"'^ joint. L. d 28-6 mm. o unknown.

Pseudorostral lobes extended along the eyelobe to its extremity; antero- 

 lateral corners acutely produced ; behind these the lower margin of the cara- 

 pace for some distance minutely denticulate. Carapace much narrowed in 

 front; medio-dorsal line carinate, strongly in first half, there carrying 4 

 strong teeth, 1^* behind the eyelobe, 4"^ a little in advance of the centre. 

 Pedigerous segment 1 strap-shaped, not overlapped by the larger 2^"^ segment. 

 Pleon segments 1 — 5 cylindrical. Telsonic segment pentagonal with rounded 

 apex, the sides between the uropods having each a series of 6 or 7 minute 

 spinules. Eyelobe narrowly linguiform, slightly expanded at apex and 

 ending in 2 little divergent teeth much as in Vmmthompsonia cristata (p. 10), 

 character of eye uncertain. Antenna 1,2^'i and 3^ joints subequal, accessory 

 flagellum obsolete. Maxilliped 3 as in Leucon. Peraeopod 2 with 3^ joint 

 said to be missing. Peduncle of uropods a little longer than the rami, flat- 

 tened, medial margin carrying 5 large and 3 little spines; endopod shorter than 

 exopod, its 1^* joint with 10 spines, 2 longer than the rest, 2"^ joint not 

 shorter but much narrower with 10 spines. L. $ juv. about 8 mm. d unknown.
