Glare Island Survey — Acarinida. 39 113 



are arranged much as in Tragardh's figure of B. littoralis (85, pi. i, fig. 1). As 

 Kramer points out in his description of B. capillata, the central one of these 

 terminal hairs about equals half the length of the segment, and is a little 

 longer than the others. Upper side of mandible with eleven or twelve pairs of 

 hairs, and on the ventral side of rostrum there are four pairs. 

 Distribution. — -Scandinavia ; Germany ; Italy ; Britain. 



Bdella longirostris (Herm.) Lam. 



Mulranny, Westport, Castlebar, and probably throughout the district. 



This brightly coloured yellow, black, and red mite is well figured by 

 Berlese (1, Fasc. xlv, n. 6). It was found commonly in a variety of situations, 

 on sand-hills, under stones on the banks of mountain streams and on more 

 than one occasion in sphagnum pools. 



Distribution. — Germany ; France ; Italy ; Britain. 



Bdella vulgaris (Herm.) Koch. 



Common. Clare Island, in moss from Croaghmore ; Mulranny ; Croagh- 

 patrick amongst sphagnum, October. 



Distribution. — Scandinavia ; Germany ; France ; Italy ; Britain. 



Bdella decipiens Thorell. 



1871. B. decijriens Thorell 81, p. 699. 1890. B. vulgaris var. littoralis. 

 Moniez 52, p. 196. 1902. B. decipiens Tragardh 85, p. 21. 



Clare Island, in rock crevices between tide-marks ; Mulranny, abundant 

 under stones between tide-marks at Bellacragher Bay in September. 



As a result of a careful comparison of the shore-frequenting Bdellas 

 Dr. Tragardh gives his reasons for believing that they are all to be referred 

 to two species, of which one is the present species, and that it is probably a 

 variety of Bdella vulgaris (85, p. 23). 



Distribution. — Has been found on the Siberian coast ; also in Sweden and 

 Spitzbergen. 



Cyta latirostris C. L. Koch. 



Mulranny, a few specimens found under stones on the sand-hills ; The 

 Bill Rocks, in sea-birds' nests ; Westport district. 



Distribution. — Apparently a common European species ranging from 

 Finland to Italy.
