reach is that annulatus is simply based on young specimens of 

 angulatus which have banded spines, and unless adult specimens are 

 found retaining this feature I do not see how we can use the name 

 even in a varietal sense. 



All of the specimens in the present collection from Saldanha Bay, 

 on the west coast of Cape Colony are conspicuous for having white 

 spines : the white is often tinged with green or rarely with purple, 

 but the pale, unicolourous spines are in striking contrast to the 

 greenish or reddish test. In view of the constancy of the character 

 and the geographical isolation of the locality, I think this form may 

 well be designated as variety PALLIDUS. The test is noticeably flat- 

 tened and the buccal membrane has very few calcareous plates out- 

 side the circle of buccal plates. None of the specimens (the largest 

 is 25 mm. h. d. and 11'5 mm. high) has an insert ocular. In some 

 particulars this variety reminds one of the Marion Island form of 

 magellanicus but when placed side by side, the differences between 

 the two forms are obvious. 



Among the specimens sent me from Capetown are half a dozen 

 young ones, two each from the lots 180, 182 and 183 of 'Bell's 

 report (1904, Mar. Inv. S. Afh, vol. 3, p. 171) and which he listed 

 as "Echimis juv." Although Bell has not seen these particular spec- 

 imens there is no doubt they are identical with his. I see no reason 

 for considering them anything but young angulosus. Aside from these 

 half dozen specimens, the localities for which are given in Bell's 

 report, the material of angulosus in the collection sent me is from 

 only the three following stations. There are however in the M. C. Z. 

 collection more than a hundred additional specimens, all of which I 

 have examined. 



P.F. 14642. Off Saldanha Bay, west coast of Cape Colony, 20 fms. 

 S., sh., r. 51 specimens; adult and young. 



P.F. 17486. False Bay, Cape Colony, 9 fms. S., sh. 14 specimens; 

 young. 



Mozambique, Nov. 1912, K. H. Barnard. 3 specimens; young.
