However, Modiolus capax and Modiolus carvalhoi are so similar, and the South West African specimens could so easily be assigned to either, that the placing of the South West African specimens presented some difficulty. The fact that Modiolus carvalhoi is geographically nearer to South West Africa than Modiolus capax has perhaps had undue influence on our decision. However, two intertidal species otherwise known only from the western American coast have been recorded from South West Africa. One of these is the species discussed above, Semimytilus algosus; the other is a brachiopod Discinisca tenuis (Sowerby), found in large numbers on the South West African coast from Liideritzbucht to the Kunene river mouth, and otherwise known only from the coasts of Chile and Peru (Dr. H. M. Muir-Wood, in litt.). On the South West African coast Modiolus carvalhoi is strongly cryptic, and occurs intertidally in the bases of algal clumps and in kelp Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
