356 ME. A. D. MICHAEL ON ACARI 



that it could not liave been introduced. Another species, Oribata 

 setosa, has formed a principal feature in almost every collection 

 of Acari which has been brought from Arctic regions ; but it is 

 equally common in England and throughout Central and even 

 Southern Europe. A third species, proposed to be called ^'■Oribata 

 'Fisheri^'' is new ; but is closely allied to Oribata antarctica, which 

 was described by me from specimens found in the Island of South 

 Georgia (Antarctic Ocean) * ; but although it is more nearly 

 related to this species than to any other, yet the two vary so 

 little from Central European forms that an acarologist would 

 not be at all surprised at finding both in England.

Unfortunately the specimens arrived in such poor condition 

 that I can add little, if anything, to Mr. Eisher's careful drawing 

 which accompanies this paper, and which was made from life on 

 the spot ; the species appears to be unrecorded. 



Cephalothorax and abdomen very distinctly separated. "Whole 

 creature rosy pink, with two irregular longitudinal bands of 

 brown spots on the abdomen. Palpi carmine. Abdomen almost 

 parallel- sided ; truncated anteriorly ; rounded, but with a slight 

 tendency to be pointed posteriorly. Two longitudinal rows of 

 short straight hairs on the notogaster ; five radiating hairs on 

 hind margin. Legs thin, gradually diminishing, with dark trans- 

 verse bands at the articulations ; some fine scattered straight 

 hairs on the legs. The claws are not drawn, and the specimens 

 brought home have lost them. I doubt whether the specimens 

 are mature. 



Abundant under stones.

Three specimens from the talus. They were coral-red when 

 living. This species has been recorded by Thorell from Spitz- 

 bergen and by L. Koch from various parts of Siberia and 

 Novaya Zemlya. The genus Bhagidia appears to me to be 

 identical with Norneria, Canestrini : and in my opinion the two 

 should not be retained. Norneria is a genus containing very
