Pelops phaenotus C. L. Koch. 



Slopes of Croaghpatrick in sphagnum, October. 

 Distribution.— Germany ; England; Italy. 



Oribata sphagni Michael. 



Local. Croaghpatrick, amongst moss on stones in a small stream on the 

 lower slopes of the mountain, July ; also a few specimens amongst wet 

 sphagnum, at about 600 feet, in the same locality in October. 



The Croaghpatrick specimens measure about -530 fi in average length. 

 Mr. Michael points out that the pseudostigmatic organs are hidden in this 

 species occasionally, however, these organs are extended. They are small 

 with a very slender stalk and large globular head. There are two fine, widely 

 separated, interlamellar hairs. On the abdomen there is a marginal row of 

 fine hairs and a few pairs are present on the dorsum of the animal. 



Distribution. — Germany (Sellnick); England 'on sphagnum, Michael); 

 Scotland 'Evans). 



Oribata gracilis Michael (var. major Berlese). 



The Bill Bocks, in debris from old nests of gulls and puffins, June; 

 Achill, under bark, September ; Delphi, in moss ; Mulranny, on the sea-shore, 

 m September. 



Berlese has described and figured, from Irish specimens, a variety of 

 this species (var. major) which is larger than the typical form measuring 

 520^-640^ in length, and the pseudostigmatic organ is "longe fusiformibus, 

 subplumosus" (7, p. 29). The above recorded specimens are possibly to be 

 referred to this variety. They measure from about 520^ to 539^ in the 

 length of the body, the pseudostigmatic organs are long and fusiform, 

 somewhat bent at the base and their extremities are finely spinous. 



Distribution. — Italy ; Holland (in decaying leaves, Oudemans) ; England 

 (in moss on trees, Michael) ; Scotland (Evans).

A tew specimens found in moss on Croaghmore mountain, Clare Island, 

 also on Achill Island, and in the Westport district (Croaghpatrick, &c, in 

 sphagnum).
