marked in capensis whereas in the Hawaiian species, the purple fades 

 out more gradually in the midzone. In view of all these differences, 

 even though each is trivial in itself, it seems to me the two forms 

 must be regarded as distinct species. Both are abyssal forms, while 

 the other Recent species of the genus are inhabitants of the con- 

 tinental slope. The African species cannot be confused with the 

 Atlantic species, cubensis, the conspicuous purple of the abactinal 

 surface distinguishing it at a glance. But it agrees with that species 

 in having the peristome distinctly smaller than the abactinal system, 

 and in the general character of the ophicephalous pedicellariae. 



SALENIIDAE. 



This small, but old and interesting, family of little, deepwater 

 sea-urchins is represented on the Agulhas Bank by the following 

 species. No other saleniid is known nearer than Tristan d'Acunha. 



* SALENIA PHOINISSA.

 lein, 1906, VALDIVIA Ech., pi. XXI, figs. 2, 1 2 (as S. pathrsom). 



This is one of the characteristic species of the Agulhas Bank, where 

 it was taken by the VALDIVIA in 56 fins.; but it must be rare, as 

 it has not been met with by the PIKTER FAURE. The only other 

 living members of the genus are found in the West Indies and near- 

 Japan. 



STOMOPNEUSTIDAE. 



This family contains but a single genus and probably the following 

 widely distributed Indo-Pacific form is the only species. 



STOMOPNEUSTES VARIOLARIS.

There are two specimens in the collection before me, taken at 

 Mozambique by Mr. K. H. Barnard in November, 1912. The species 

 has long been known from this place but its occurrence south of 

 there is doubtful. Mr. Agassiz, in the "Revision", lists a specimen 

 from Natal, as occurring in the Stuttgart Museum, but there is a 

 strong probability of a mistake in the label,
