Crustacean Fauna of South Africa. 17 
than that of C. longipes Stebbing, but the mandibular process 
narrower and more acute. 
Mandible, cutting-edge tridentate in the one (? left), 6-dentate in 
the other (? right), secondary cutting-edge 3- and 4-dentate respec- 
tively, spine-row with 6 spines, molar prominent, denticulate, palp 
long and slender, 3rd joint equal to Ist and 2nd together. 
First maxilla, inner plate rounded, with 3-4 setae, outer plate with 
11 spines, palp longer and not much narrower than outer plate, 2nd 
joint not distally widened, apex with 7-8 spines and 2-3 fine setules, 
outer distal margin with two widely spaced setae. 
Second maxilla, inner plate only a little broader than outer, apices 
of both plates rounded, setose. 
Maxilliped, apex of inner plate with 3 short blunt spines, outer plate 
reaching to middle of 2nd joint of palp, outer margin and apex setose, 
inner margin straight, unarmed, but with a row of fine setae some 
little way within the margin, 4th joint equal to 5rd. 
First gnathopod, 2nd joint distally expanded, club-shaped, hind 
margin with a row of close-set spines, 5th joint large, triangular, 
inferiorly lobed and bearing stout setae, 6th joint as long as 5th but a 
little narrower, ovate, palm very oblique, undefined, with 9 spines and 
5 groups of setae, 1 long and 2 short in each group, 7th joint long, 
nearly reaching base of 6th. 
Second gnathopod similar, but 2nd joint more prominently club- 
shaped, and 5th joint more strongly lobed. 
First peraeopod, 2nd joint slightly expanded distally, hind margin 
with spines as in the gnathopods, 4th joint 2 length of 2nd, 5th 
nearly } length of 2nd, 6th subequal to 4th, its inner apex with a 
group of short spines, outer apex with 2 siniple setae and 1 long plumose 
seta, 7th joint rather more than } length of 6th, rather stout, curved. 
Second peraeopod similar, but 2nd joint not so much expanded, and 
spines on hind margin weaker. 
Third peraeopod longer than the other peraeopods, 2nd joint 3 
times as long as broad, front distal margin very finely setulose, with 
5 widely spaced spines, hind margin with a few fine setae, 4th joint 
longer than 5th, both with very fine pubescence on front margin, 6th 
joint longer than 4th, subequal to 2nd, inner margin with 8 groups 
(usually pairs) of small spines, 7th joint } length of 6th, curved. 
Fourth peraeopod, 2nd joint twice as long as broad, front distal 
margin with 2 spines, hind margin as in third peraeopod. 
Fifth peraeopod a little shorter than fourth, 2nd joint half as long 
again as broad, front margin with a few setae only, hind margin 
convex, with very shallow serrations, each bearing a setule.
