Some years ago I was in Malta, and I used to go and watch them on the slopes outside Valetta, where they were to be found in great numbers. They used to come out from beneath great stones and run about rapidly on the ground or on the stones and rubbish with which the ground was covered, now and again making a dart at some small insect which tempted them, and seemingly not minding the blazing sun at all. As might be expected from their habits, their eyes, far from being rudimentary, like those of the cave-living _Pseudotremia_, or absent {36}like those of the Polydesmidae, or of our own _Cryptops_, are highly developed, and form the only example among the Myriapods of what are known as facetted eyes. The Scutigeridae are also remarkable among Myriapods for the possession of a peculiar sense-organ which is found in no other Myriapod. The Myriapods most numerous in our own country are _Lithobius_ and _Julus_. _Lithobius_, which will be described later on, may be found in almost any garden under dried leaves, stones, etc. _Julus_, the common wire-worm, is found crawling on plants and leaves and under the bark of trees, and does a good deal of damage in a garden. _Polydesmus_ is also frequently found in great numbers, and usually a great many of them together. _Glomeris_ is also found, though it is not so common as the first two mentioned animals. _Geophilus_ is also common, and especially in the south of England. Scolopendridae are only represented by a single genus, _Cryptops_, which is not very common, though by no means rare. The best place to find them is in manure heaps. The animals of this species are small compared to most Scolopendras, and have the peculiarity of being without any eyes. _Scutigera_ is unrepresented in this country. One was found in Scotland some years ago by Mr. Gibson Carmichael, but was shown to have been imported, and not bred in the place.
