Show I fancy that the single papilla at the base of the penial process is rather nearer to the base than is figured by Michaelsen, and much nearer than in the West-African form, and, moreover, it appeared to me to be not symmetrical in its position. The clitellum was not seen by Michaelsen at all. In my specimens the clitellum occupied the same segments; but, as in the species described by myself from Western Africa, that generative region was somewhat undefined in its beginning and ending. The greatest number of segments referable to the clitellum in the West-African species are from xlv.-lxxxv.; but the clitellum was only fully developed upon segments xlvii.-lxxxii. Its general appearance was precisely like that of the species which I have just mentioned. In the present species-and the observations apply to more than one specimen, and are therefore all the more reliable as an expression of normal conditions-the clitellum was much shorter, onty extending from segments xl.-lxxi. This rather leads me to the inference that the species with which I am concerned here is in reality different from that which I described from McCarthy Island on the Gambia, and ref erred to A . stuhlmanni. The present worm is undoubtedly A. stuhlmanni; and it seems to be necessary, on account of the difference in the clitellum, to use another name for the West-African form. I would propose, therefore, to call the latter A. budgetti. It is, however, clearly a very close ally of A . stuhlmanni. It is interesting to note that the species of this genus go more or less in couples. The East-African A. nilotica corresponds to my A . millsom from West Africa, while A . stuhlmanni seems to be nearest to the form which I propose to name A. budgetti. At present more information is wanted about A . emini; but it appears to be formed rather after the plan of A. millsoni and A. nilotica. For in those species there are special setae on the penial processes, while in A. stuhlmanni and S. budgetti there are setae of the same pattern as those on the body generally. 222 PROF.

I received a letter from you in August 1900, following on an account, written by me in ‘ The Field,' of an interview I had with White Rhinoceroses about that time. I did not answer your letter at the time, hoping I should be able before long to send you a photograph of the living animal. This, however, I |
