THE BRITISH WOODLICE. 105 BRITISH LOCALITIES :— England : Matlock ; (T.R.R.S.) Arnside ; Westmorland (Brady, 50a). Ireland: Ballymote, (Irish Nat., May, 1901), Sligo ; (Scharff). FOREIGN DISTRIBUTION :— Europe : Vosges ; Switzerland; Pyrenees; (23) : Forest de Soignes ; Belgium ; (14). Armadillidium depressum Brandt. Plate XXV. 1833 Armadillidium depressum Brandt (3), p. 82. pl. XII., figs, 4, 5, 6, C, D. 1892 Armadillidium depressum Dollfus (14), p. 17-18. The frontal lobe in Armadillidium depressum is very prominent and much recurved. The antennae are fairly long and while the two joints of the flagellum are nearly equal they are together not so long as the last peduncular joint. The telson is slightly longer than it is broad at the base, and its sides are incurved. As in Armadillidium vulgare and Armadillidium pulchellum the outer divisions of the tail appendages are broader than they are long. The body is flatter than in the other species and bears tubercles; its colour is a slate-grey with yellowish markings. The first thoracic segment is well developed and the head appears as if almost completely imbedded in it. BRITISH LOCALITIES:— England: Clifton, banks of the Avon ; (W.M.W. from J.T.C., 1900): Shirehampton, near Bristol; (Stebbing in 49): Clifton ; (Dollfus from Miers 14). FOREIGN DISTRIBUTION:— Europe: France; Italy ; (25) : Asia Minor ; (14, quoting Brandt). Distribution of Species. There are not sufficient records at present to enable us to draw any conclusions as to the general distribution of Woodlice in the British Isles, but it is hoped that more attention will be given to these creatures, and that before long there may be other material available. Conclusion. At the beginning it was mentioned that the present work grew out of an investigation into the fauna of Essex, and in order to show what may be expected when places
