Show 1890.] ACARINA FROM ALGERIA. 419 similar hairs on the hind margin at the dorsal level, besides two pairs at the ventral level. There is a very thick, almost fusiform hair projecting on each side from the shoulder, and a long stiff hair on the edge of the abdomen a little further back. All these hairs and indeed almost all those on the creature, are slightly rouo-h or imbricated if seen by a high amplification ; but, excepting perhaps those on the legs, they cannot be called serrated. Genital plates roundish; anal plates almost square, far from the genital. I found several specimens of this species at H a m m a m R'hira Algeria ; but just before leaving England for m y Algerian journey I received a collection of Oribatidae from the Rev. C. R. N. Burrows which he had coUected in the district of Lake Winnipeg, Canada, and that collection contains an example of the present, hitherto unrecorded, species. I have named it after Mr. Burrows.
