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 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 genit;il. 



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 Oribatidas 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.
