basal 3 and the distal 2 setae. First antenna with a row of 7 stout 
spines, besides several sets, on anterior margin of Ist joint, each spine 
arising from a small indent, flagellum subequal to peduncle, 17- 
jointed. Second antenna with peduncle rather longer than first 
antenna, ultimate joint shorter than penultimate, flagellum 80-90- 
jointed. First and second uropods with outer basal surface of 
peduncle setose, upper and inner margins spinose, basal half of outer 
and inner margins of both rami spinose. Third uropod similar but 
shorter than 2nd. Telson with apical margin straight, postero-lateral 
angles rounded, as in O. /ahillei Chevreux.

The Cape specimens differ from the typical form only in the small 
details above mentioned. There are no traces of the eyes or any 
pigment in any of the specimens; and in this respect the specimens 
approximate to O. proximus, unless the method of preservation, 6 years 
in formalin and then alcohol, is responsible for this feature. The 
number of setae on inner plate of first maxilla is also nearer O. proximus 
than O. cinderella. In all other points, however, the present specimens 
are inseparable from the latter species.
