Jeffrey Bell has been so good as to forward to me for identification a number of earthworms which were collected by Mr. L. S. Ilinde, C.M.Z.S., at Titui, in elevated country some 3000 or 4000 feet in altitude. The specimens were sent to Prof. Lankester at the Museum, and are of two, possibly three, species. The larger individuals, of which there are three specimens with the head end perfect, belong to the genus Polytoreutus, a genus that is, so far as we know at present, peculiar to East and Central Africa; the small worms are referable to the genus Benhamia. Of the larger specimens two at least belong to an undescribed species of Polytoreutus; while the third, upon which I shall offer some necessarily brief observations, seems to me not to belong to that species, but to some other which may or may not be new. I shall call the new Polytoreutus. POLYTOREUTUS HINDEI, n. sp. The larger of the two specimens, the only one which is absolutely complete, is also fortunately fully mature, with the clitellum developed-so far as I can judge-to its full extent. It measures 130 mm. in length and is a fairly stout worm, having a diameter of 5 mm. The external characteristics of this species enable it to be distinguished from any other species; it seems to bear the closest likeness to Polytoreutusfiuni, to which species its internal anatomy also affines it; but there is uo possibility, I believe, of confounding the two species. Tbe present form is, as has been said, a fairly large and stout worm. Polytoreutusfinni is strikingly characterized by its length and slenderness. Nevertheless the appearance of the area which surrounds the generative pores has a certain likeness in the two species, both of which differ in this respect from other species of Polytoreutus. As will be seen from the accompanying drawing (text-fig. 83, p. 337), the ventral area of the |
