on dorsal margins, outer has 5 spines on outer margin and 3 small ones distally on inner. Second: Peduncle margins naked except for strong spine on each distal angle; inner ramus has 6 and 3 spines dorsally, outer has 5 and 3. Third: Peduncle has 1, 2 and 1 spines dorsally; inner ramus has 4 and 5 spines, outer has 6 on outer margin only; inner margin minutely pectinate. Telson: Apices acute. Types. Slides C.102.

Akaroa, 4. × 13, Chilton Collection (C.102, an ovigerous female, of 8 ½ mm. length; C.105, male); “Lyttelton-Dunedin” (C.103, female), an ambiguously labelled specimen from the Chilton Collection. “Off West King, ‘Hinemoa,’ 5.1.15,” 60–65 fathoms, Chilton Collection (Slides C.109, male). Discussion This species has a similar third epimeral plate to that found in L. georgiana, L. macrodon, L. longicornis, L. barhami, and L. quinquedentata. It is distinguished from the first four of these amongst other things by its lack of strong urosome spines. There are also differences in gnathopod and peraeopod basos shape. Maxilla 1 inner plate in L. quinquedentata has 4 setae (could this be Pirlot's L. aequabilis [1936]?), and the 1st pleon segment does not have 3 teeth. The telson and serration of the basos in Pr. 3–5 separate L. macrodon from L. akaroica. Some of the differences between these species may not be great but in the present state of the genus, I consider them sufficiently distinct to warrant granting L. akaroica specific rank in its own right. Liljeborgia akaroica var. maria n.var. (Figs. 181–183). This is like L. akaroica akaroica but the first antenna has 10 and 15 segments; the second has 9 setal groups on the 5th peduncle segment, the flagellum has 14 segments. The gnathopods have 6 and 9–10 dactylar teeth. Peraeopods 1 and 2 propods have 7 short spine-setae, the margin between them finely combed, the peraeopods otherwise like those in L. akaroica akaroica. The serrations of the posterior margin of peraeopod 3 basos are more distinct, the merus posterior margin has 3 long spines, the anterior has 3 pairs of spines. The second uropod has 2 and 3 spines on dorsal margins of peduncle, 6 and 2 spines on one ramus, 4 on the other. The third has 3 spines on the peduncle, 3 and 2 on inner ramus, 4 on the outer ramus margin, naked inner margin finely pectinate-combed. Type. Slides P.106, male. Locality. “10 miles NW of Cape Maria, 80 fathoms, ‘Hinemoa,’ 5.1.15,” Chilton Collection, 3 specimens. Discussion Whilst these differences are not sufficient in my opinion to warrant a separate species, particularly on such scanty material, the differences in the propods of peraeopods 1 and 2 cannot be completely disregarded. Granting varietal rank seems the most satisfactory course until further material is available. Liljeborgia barhami n.sp. (Figs. 184–201). Pleon segment 1 has 1 very small tooth dorsally, 1 strong dorsal spine on each of urosome segments 1 and 2.
