56 Cumacea: 6. Chalarostylidae, 2. Hemilamprops 



accessory 2- jointed. Antenna 2 in Q with P* joint carrying 3 plumose setae, 

 its length subequal to 3 following joints combined. Peraeopod 1 fully Ufiae 

 as long as the carapace, 2"<^ joint much shorter than the rest combined, among 

 which the Ht^i joint is much the longest. In peraeopod 2 the 6^^ joint is 

 shorter than any but the 3^. In the 3^ and 4**^ pairs the 2°*^ joint is much 

 longer than the rest of the limb, slender in the g with small 2-jointed exopod 

 attached near the base, but stout in the d with exopod fully developed, 

 the 3^ pair in the c5 carrying on the 3'^ joint 2 smooth falciform spines. 

 Peraeopod 5 small, normal. Uropods slender, peduncle not longer than the 

 exopod, in which the 1^* joint is about two-thirds as long as the second, 

 the two together not quite equal to the first 2 of the endopod, which has 

 about 15 spines on the medial margin of its long 1^* joint, 4 on the second, 

 and the still shorter 3^ furnished with 5 little spines round the apex. Colour 

 crimson, in ramified stellate patches. L. 9 6 mm, d 7 mm.

Near to //. rosea, but eye imperfect, without lenses, pigment whitish; 

 peraeopod 1 rather less slender, (^^^ joint scarcely as long as, instead of longer 

 than the 3 preceding joints combined; peraeopod 3, with the 2 peculiar 

 spines on 3^ joint in d more slender, not falciform, distally annulate and 

 on one side denticulate; telson more narrowed distally, with single pair of 

 slender lateral spines, only 6 apical, the outermost pair much the longest; 

 body semipellucid, unpigmented. L. 5 mm, d 6 mm (Sars, 1899); Q 6-5 mm 

 (Sars, 1883).

Pseudorostral lobes little prominent, smooth, apically rounded. Carapace 

 smooth, except for medio-dorsal serrate carina reaching nearly half Avay along 

 with 26 teeth, of which 6 are on the prominent but sightless eye-lobe; 

 2 slight submedian furrows on the hinder half of the carapace. The telson 

 is about four-fifths of the length of the peduncle of the uropod, its sides 

 serrate, the hinder half carrying 7 pairs of strong spines in the d, 5 in 

 immature 9 , the apex 5 spines of which the central one is much the longest. 

 Antenna 1 with flagellum of 5 short joints, accessory 3-jointed, two-thirds 

 of length of the principal. Antenna 2 of 9 with a single plumose seta on 

 each of first 2 joints. Maxilliped 2 with 3^^ joint fused or lost. ^Peraeo- 

 pods 3, 4, with rudimentary 2-jointed exopods. Peduncle of uropods shorter 

 than the rami, of which the endopod is only a little the longer, carrying 

 on the medial margin of its 3 joints 8, 4, and 2 spines respectively; the 

 exopod, as figured, has the first joint somewhat longer than the second* 

 L. d 10 mm. 9 a little less. None of the specimens fully adult. ;
