Excerpt from An Annotated Check List of the Parasites of Animals in Puerto Rico The parasites of animals established ln Puerto Rico, some 200 spe cies, are also, with but few exceptions, found on the continent of North America. However, owing to differences ln climatic and other factors there is considerable variation in the abundance of different species in the island as compared with the same species on the conti nent. As all the species of mammals now existing in Puerto Rico, except bats, have been introduced there are no native species of fixed parasites in them.
