Spencer Cobbold, M.D., F.R.S., Professor in the Royal Veterinary College. I HAD barely corrected and returned the proof of my previous paper on this subject when I received another set of entozoa from India. In accordance with the promise quoted at page 742, Lieut.-Colonel Hawkes had promptly transmitted a small phial containing amphistomes from the ox. They arrived on the 29th of September, and were labelled as having been “ found in the intestines only.” The specimens are sixty in number. All of them have a more or less shrivelled appearance and show greater variation in size and aspect than any of those previously received. This is neither the place nor occasion to offer minute comparisons between the different species of amphistomes in general, but, so far as my observations have extended, I feel bound to say that the study of this curious group of parasites is one of great diffi- culty, supposing the intention of the observer be to define the various species. Since the monographs of the learned Diesing appeared, some thirty-five years ago (and before that savant lost his sight), very little attention has been paid to the subject. The species run so closely together in character that it is hard to draw any sharp lines of demarcation between one form and another. From the materials already in my possession I hope ere long to offer a more strictly scientific account of the several forms already indicated as new to science ; but in the meantime I am concerned only or chiefly to enumerate these forms with their habitats and to dwell upon the practical bearings of the subject. In addition to the two species announced in my last paper, namely, Amphi-](https://iiif.wellcomecollection.org/image/b22431263_0003.jp2/full/800%2C/0/default.jpg)
