A. C. OUDEMAXS, NOTES ON ACARI. 289 



slender, the legs rather slender, each with a sticking sucker, 

 which is drawn like a funnel, and too large. Claws are not 

 drawn, apparently tliey were minute. Along the edge of tlie 

 body a row of minute hairs. Noticeable are two longer hairs 

 on the posterior margin of the body, apparently planted on 

 the edge of tlie shield. On the ventral side the legs are drawn 

 in a situation which is unknown in Acarids, as is already 

 stated above. Something like a sternal shield, longer than 

 wide is discernable ; posteriorly the anus, behind it there 

 are two hairs, longer than usual. Further a rather long and 

 pointed hypostome. 



If we compare now Bering's descriptions and drawings with 

 mine here following, we must acknowledge that the probabi- 

 lity that the two animals are the same amounts to certainty.
