REPORT ON HYDRACARINA 



By O. Lundblad, Stockholm 

 (Received March 1, 1934) 



During the course of the Yale North India Expedition, Mr. G. E. Hutchinson collected 

 some water-mites, which he has asked me to work out. Because of the high altitudes at 

 which the main part of the material was collected, only some few species are represented. 

 Nevertheless the collection is a highly interesting one, forming a very valuable contribution 

 to our poor knowledge of the water-mite fauna of India, and it is a great pleasure to me to 

 offer Mr. Hutchinson my best thanks for giving me the opportunity of studying his material, 

 which contains quite a number of forms new to science.

The collection contains some few, more or less mutilated, specimens, nioslly without legs 

 and palps. 



In all characters still available for study the specimens agree well with European material. 

 The species was found for the first time in Palestine in 1895 and described from German 

 material in 1897. Since then it has been found in many other countries, as will be seen from 

 the foregoing list, which, however, does not complete the synonymy. Earlier authors, who
