ERRATUM. 
P. 66. For Pecten capensis, Gray, read PECTEN (VOLA) SULCICOSTATUS, 
Sowerby, pl. 5, figs. 97, 98, Thes. Conch., vol. i. p. 7, pl. xiii. figs. 35, 36: 
Dunker, Novitates Conch., ‘Meeres Conchylien,’ p. 67, pl. xxiii. figs. 4-6 = 
Pecten capensis, Gray (mss. in Brit. Mus.), Hab.: Natal coast (Dunker), 
Cape of Good Hope (Brit. Mus ), Port Elizabeth. The shell figured plate v. 
has been in the British Museum since 1837, named P. capensis, Gray, but 
it does not appear that any description of it has ever been published under 
that name. The specimen is very much larger than the original type, but 
I have no doubt as to its identity.
