In my paper on the South African Echinoderms {op. cit., 1933, p. 302) I remarked 

 that the only difference I could find between the South African and the South American 

 form of this species was that in the South African form there is only one spine at the 

 proximal five or six pore pairs, whereas in the Magellanic form there are two spines 

 already at the third or fourth pore pair. The specimens in the present collection all have 

 two spines from the third or fourth pore pair, which seems to indicate that this dif- 

 ference is reliable, so that it may be possible to distinguish the South African form as 

 a separate variety, var. capensis, n.var. 



The specimen from off Tristan da Cunha, a locality from which the species had not 

 hitherto been recorded, agrees with the typical South American form in regard to the 

 numbers of spines at the proximal pore pairs. 



Ludwig {op. at.) proved that Ophioscolex Coppingeri of Bell was identical with 

 Ophiojnyxa vivipara. Having seen the type-specimen of Bell's species in the British 

 Museum, I can confirm the result reached by Ludwig.

Referring to the observation recorded in my paper on the New Zealand Ophiurids 

 (p. 113) that two types of breeding occur among the specimens identified as O. brevirima, 

 viz. one having the bursae filled up with a great number of small embryos, the other 

 having only one young in each bursa (a difference tending to indicate that the two types 

 in reality represent two distinct species), it should be mentioned that the present
