ARACHNOIDEA, 



CASE -by Dr. Maddox in the Monthly Micro. Journ., 1871, obtained 

 from the ears of a pipistrel from Scotland, and from these we 

 see that Kolenati has fallen into error on some important points.

not unreasonable to conjecture that he got most of his species of 

 bat-mites from the dead or dried specimens of bats in the museum, 

 which, of course, are less favourable for accurate observation than 

 fresher specimens. Whatever be the cause, however, he 

 V I has fallen into the mistake of saying that the legs of 



\y this genus are eight-jointed when they are only five- 

 jointed ; its palpi four-jointed when they are only three- 

 jointed, and figures them as projecting instead of lying 

 close to the mandibles; and the other parts of the mouth, 

 as described by him, are not recognisable when com- 

 pared with those figured by Dr. Maddox. The reader 

 may say '' They cannot be the same." So we thought at 

 first 3 but after studying them again and again, and find- 

 ing that they agreed in every point on which error was 

 difficult, and only differed on those where error was
