margin, the short trianglar fifth joint underriding the sixth and 

 having its base deeply imbedded in the fourth. The finger i» 

 shorter than the sixth joint, and as in all the trunk limbs has a 

 short, dark-coloured nail, preceded by a small spine, which gives 

 a biunguiculate appearance to the joint. 



Second gnathopods — The spines on inner margin of fourth 

 joint are arranged in two sets separated by an unarmed interval ; 

 the fifth joint is small, but does not underride the sixth, nor is it 

 imbedded in the fourth; the sixth joint is much less stout than 

 in the preceding pair. 



Peraeopods — i he first pair is similar to the second gnathopods 

 The other four pairs have the joints longer, especially the last two 

 pairs which are subequal- There are no plumose setae on these 

 linijbs, but spines at the apices, and a few on the inner margins of 

 the third to sixth joints. 



Pleopods — The rami are broad in all of them- 

 Uropods — The peduncle is produced rather beyond the middle 

 of the telsonic segment, but not quite to the middle of the inner 

 ramus ; this ramus is very broad, and reaches beyond the 

 segm,ent, its margin, except near the base, being closely fringed 

 wdth spines and setse ; the outer ramus, though about as long as 

 the mner, does not reach nearly so far back,, and is much narrower, 

 but with similar armature. Colour, in formalin, cream, with 

 symmetrical brown markings on upper surface, but not on under 

 surface or on appendages, except the uropods. Length, 15 mnH., 

 or a little less or more. 



Locality: — Table Bay, and from " Red Bait" (a large Ascidian)^ 

 Somerset West, shore. 



Krauss, loc. cit, under C- sculpta, j\L-Edw., says. "' A specie* 

 distinguished by the exceedingly pretty marking of the abdomen, 

 which I have found in Table Bay- Yellowish green, with black 

 speckles and spots. Length, 6 fines." Herklots in 185 1 merely 

 mentioned the name on Krauss's authority. Hansen doubts the 

 identification^ and is disposed to think, from the strong sculptur- 

 ing of the pleon, that JNIilne-Edwards's species may be a 

 CoraUana. Milne-Edwards thus describes his C. sculpta: — 

 " Head much broader than long, scarcely narrowed anteriorly, 

 and little immersed in the thorax. Marg-in of the last thoracic 

 rings and of the rings of the abdomen finely denticulate- The 

 last segment of the abdomen furnished with a conical tooth on 

 the median line, with a multitude of- little crests, and ending 

 behind acutely. Feet feeble, and scarcely hairy. Terminal plates 

 of the uropods almost of the same size and apically acute. 

 Length, about 9 lines- From the coast of ^Malabar." 



The description of the uropods will not at all suit the present 

 species, an4 the distance of habitat does not encourage the hypo- 

 thesis of misdescription. Milne-Edwards also says that in his 

 species the head is scarcely narrowed in front ; in the South
