basal 3 and the distal 2 setae. First antenna with a row of 7 stout 

 spines, besides several setae, on anterior margin of 1st joint, each spine 

 arising from a small indent, flagellum subeqnal 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 rarni spinose. Third uropod similar but 

 shorter than 2nd. Telson with apical margin straight, postero-lateral 

 angles rounded, as in 0. lahillei 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 0. 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 0. proximus 

 than 0. Cinderella. In all other points, however, the present specimens 

 are iusepai'able from the latter species.

 ceding but rather longer, whole posterior margin emarginate, 5 bilobed, 

 lobes subequal, 6 subquadrate, 7 shallow. Postero-inferior angles of
