Clare Island Survey — Acarinida. 39 101 



Scutovertex corrugatus Michael. 



Mulranny, common under stones on the sea-shore at high-water mark in 

 September. 



Distribution. — According to Tragardh this interesting species is identical 

 with Eremaeus Hncatus Thorell (83). It has therefore an extremely wide 

 range in north-western Europe i.e. Siberia, Novaya Zemlya, Spitzbergen, 

 Baren Insel, Sweden, and Sellnick records it from the Faroes. In Britain it 

 was first discovered by Mr. Bostock at Puffin Island, North Wales, " crawling 

 on fresh-water algae (Prasiola stipitata and Cladophora fracta), where the 

 fresh water was dripping over the rocks close to the sea, but not where the sea 

 would come " (48). At Mulranny it was most abundant under stones where 

 a small stream flows into the sea at the head of Ballacragher Bay, but it 

 was by no means confined to the fresh water. 



Scutovertex maculatus Michael. 

 Has been found on the shore of Lambay off the Dublin coast (31). 



Cepheus bifidus Nicolet. 



Westport district, a few specimens found amongst moss at Knappagh

 its curiously formed nymph, September.

Carabodes elongatus (Michael). 



Clare Island, Achill, and Westport district. Frequent in moss. 



Distribution. — There are few records of this species, it is widespread,
