Cysticercus bovis Cattle Cysticercus cellulosa Swine and man Cysticercus tennicollis Cattle, sheep and swine Coenurus cerebralis Cattle and sheep Echinococcus polymorphus Cattle, sheep, swine and man The adult tapeworms Taeniae saginata and soleum, of which the Cysticerci bovis and cellulosa are the larvae forms, occur in man.
S.P. Woodward, are no longer inhabitants of the contiguous sea, as, for example, Strombus bubonius, which is still living on the West Coast of Africa, and Cerithium procerum, found at Mozambique; others are Mediterranean species, as Pecten Jacobaeus and P. polymorphus.
E. polymorphus is a parasite of the liver, but it may occur in other organs. THE THORN-HEADED WORM OR ACANTHOCEPHALE. This parasite requires a secondary host. In this case a particular species of the May-beetle larva or white grub that is commonly found about manure piles and in clover pastures is the host. The hog eats a white grub that is host for the larval form.
The cladonias appeared to me to be identical with the Lichen rangiferinus, the L. pixidatus, and the L. polymorphus of Linnaeus. After having passed the rapids of Guarinuma, the Indians showed us in the middle of the forest, on our right, the ruins of the mission of Mendaxari, which has been long abandoned.
The larvae forms of these taeniae are the Cysticercus tennicollis, Coenurus cerebralis and Echinococcus polymorphus. C. tennicollis is a parasite of the serous or lining membranes of the body cavities. It is not of great economic importance. C. cerebralis is a parasite of the brain of sheep, and may cause a heavy death rate in flocks that are infested with it.
The presence among them of Lutraria rugosa and Pecten polymorphus, not known to range farther north in the actual seas than the coast of Portugal, indicates a somewhat warmer temperature at the time when they flourished.
