HARDWICKE'S SCIENCE-GOSSIP. 



THE BRITISH FRESH-WATER MITES. 



DURING the past season, I have met with four 

 males, belonging to the family Arrenurus, 

 which are not figured in my former papers. I now 

 send you sketches, and short descriptions. 



The gatherings, with one exception, were taken 

 by Ed. Scudamore, Esq., B.A., and are not from my 



given in the February number of Science-Gossip 

 for 1883, page 37. 



It is of a beautiful red colour, like vermilion, only 

 transparent — it has the peculiar process on the last 

 joint but two, of the hind leg, very highly developed. 

 As in all the males of Arrenurus, the tail part is very 

 characteristic.

immediate neighbourhood. One of the mites, so far 

 as I know, is new to Science, and I have therefore 

 named it ; if, however, it has been before described, I 

 should be glad to be referred to the description, and 

 withdraw my name, which is only provisional, and I 

 feel not so good an one as it deserves, for it is a 

 most beautiful and distinct species.

creature is at once recognised by its unusually 

 elongated form, and the two peculiar little tubercles, 

 at the end of the tail. It is of a lovely green colour, 

 with vermilion eyes, surrounded by a yellow-green 

 colour. CcEca of a warm brown colour. The process 

 on the last joint but two of the hind legs is well 

 developed.
