There seems to be some doubt, however, as to whether _Ju´lus_, one of the commonest Millepedes, does not occasionally indulge in animal food. In _Nature Notes_ (Jan. 1896) there was a review of the _Cambridge Natural History_ (vol. v). The reviewer, in a brief summary of Mr. Sinclair’s part of the book (the Myriapods), said, after describing the Centipedes: ‘The millepedes, on the contrary, are sluggish vegetarians, with hard, cylindrical bodies, &c.’ On this a correspondent wrote in the March number: ‘Some time ago my attention was attracted to a large earthworm, writhing and twisting about on the garden path, as though in pain, or through having received some injury. On examining it more closely to ascertain the cause of its unusual movements, I found that a millepede had fastened itself to the side of the worm, and appeared to be boring or eating its way into the body, whilst the most violent efforts on the part of the worm were ineffectual in shaking off its antagonist. If the millepede is a vegetarian, what could be its object in attacking so harmless and defenceless a creature as the earthworm? The above, which I take to be a millepede, is the black or dark-coloured creature “with hard, cylindrical body” ordinarily found coiled up in a spiral under stones or rubbish.’ The editor, as a matter of course, referred the matter to the writer of the review. His reply was as follows: ‘If there is no mistake about the identity of the aggressor in the account cited above, the observation is one of considerable interest; for, so far as we are aware, it is the only case on record of a millepede being guilty of such conduct. But were it not for the positive statement that the species was the dark-coloured creature with a hard, cylindrical body, which is ordinarily found coiled up in a spiral under stones or rubbish--a description which exactly applies to the millepedes of the genus _Julus_--we should have concluded without hesitation that the struggle in question was merely one of those that habitually takes place between the centipedes of the genera _Litho´bius_ or _Geoph´ilus_ and the earthworms upon which they feed.’ Both the Centipedes and Millepedes are shy, light-shunning animals, and if we turn over some stones in the garden or in a walk through the fields we shall probably find specimens enough to serve us in getting some idea of both groups. The Centipedes are sometimes called ‘Hundred-legs,’ but this implies the possession of many more legs than the creatures really have. In Norfolk and Suffolk the people call them ‘Forty-legs,’ and this is much nearer the mark.
