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 aU those on the creature, are slightly rough 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 genitnl. 



I found several specimens of this species at Hammam R'hira, 

 Algeria ; but just before leaving England for my Algerian journey I 

 received a collection of Oribatidoe from the Rev. C. R. N. Burrows, 

 which he had collected in the district of Lake Winnipeg, Canada, and 

 that collection contains an example of the present, hitherto unre- 

 corded, species. I have named it after Mr. Burrows.
