This paper consists of several parts which, while dealing with parasites of the agouti, are quite separate in themselves. A general historical account therefore, may be both disconnected and confusing. Wherever it is possible to do so, an account of previous work will be given before each undertaking. The family Dasyproctidae including about twenty three (23) species of agoutis and pacas is peculiar to the neotropical region. Two species of this family are found in Trinidad viz. Dasyorocta agouti and Coelogenys paca. The agouti, (Dasyprocta agouti) is found also in a few of the islands north of Trinidad but, with the possible exception of the one found in Tobago, the others were most likely introduced by man. On the mainland of South America, the agouti ranges from Mexico to Paraguay.
