9 . Pseudorostral lobes subacutely produced for some distance in Irout 

 of the evanescent eyelobe, the antero-lateral margin vertical to a small sinus 

 and well marked but not far produced acute corner, which is microscopi- 

 cally serrate. Carapace a little more than two-fifths of the body's length, 

 smooth, inflated, narrowed in front as seen from above, dorsal line arched, 

 with slight depression to the rear. Pedigerous segments with side-plates 

 expanded, smoothly rounded, 1^* and 2"<^ dorsally raised into bifid laminar 

 teeth procurved. Pleou segments smooth, the b^^ widest at first third of 

 its length. Peduncle of uropods as long as 5^^ pleon and telsonic segment 

 combined; endopod as long as 5*^ pleon segment, two-thirds of the length 

 of the peduncle, exopod little over three-fourths of the endopod. L. 2-3 mm. 



S . In general form as in P. armata (nr. 4), but the eyelobe is evanes- 

 cent. There are a pah- of small spines at tip of pseudorostral lobes above. 

 Dorsal surface of carapace with group of about 10 curved spines, submedian, 

 to the rear; spines in close order just over the lower margin from antero- 

 lateral corner to the hind margin. Side-plates of last 4 pedigerous segments 

 armed with marginal teeth, a pair of dorsal spines on each of the last 3 

 of these segments. First 4 pleon segments each with pair of forward slo- 

 ping straight dorsal spines near the front and a sharp lateral spine. Antenna 2, 

 last 2 joints of peduncle subequal. Exopod of uropods about four-fifths of 

 the length of the endopod. L. 2-3 mm.

Q. Pseudorostral lobes little produced, and without lateral sinus. 

 Carapace not half the length of the body, a little compressed : eyelobe tuber- 

 culiform, carrying a pair of denticles : a submedian pair of processes behind 

 the middle of the length of the carapace carry each on its summit a couple 

 of procurved denticles. The pedigerous segments combined are about half 

 as long as the carapace. The peduncle of the uropods is rather longer than 

 the 6*11 pleon segment, the endopod about two-thirds as long as the peduncle 

 and rather longer than the exopod. Colour yellowish white. L. 9 with 

 commencing marsupium, about 4 mm.

Pseudorostral lobes a little upturned, meeting for a very short space 

 in front of the narrow bidenticulate eyelobe, laterally forming a shallow 

 sinus defined by a small tooth, which is followed a little way to the rear 

 by a similar tooth on the lower margin. Carapace well arched, not actually 

 carinate, with scattered hairs on the surface and behind the centre a little 

 denticle. Pleon segments laterally carinate, 5*^ the longest, distally nar-
