Only two species of this genus are so far known: C. megacheles 
(Giles) from Ceylon and South Africa, and C. australis Stebbing 
1910, from New South Wales. From both of these the following 
species is easily separated by the form of the 2nd gnathopods in 
the ¢. 
CHEIRIPHOTIS DURBANENSIS 0D. sp. 
Body slender and somewhat depressed. Antero-lateral angle of 
head not greatly produced, occupied by about half of the oval-shaped 
eye. Side-plates shallow, the first produced forwards to a subacute 
apex. Postero-lateral angle of 3rd pleon segment rounded-quadrate. 
Telson broader than long, distal margin concave between the postero- 
lateral angles, near both of which there is a small group of setules. 
First antenna, Ist and 2nd joints subequal, 3rd shorter, flagellum 
6-8-jointed, accessory flagellum 3-jointed, 3rd joint minute. 
Second antenna subequal to first, 4th and 5th joints subequal, 
flagellum subequal to 5th joint, 6-jointed. 
Upper lip slightly bilobed. 
Lower lip with the inner lobes larger than the outer, apically 
abruptly truncate, the inner and outer apical angles being right 
angles, outer lobes obtusely rounded.
