1922. Friend. — Irish Enchytraeids in the Faroes. 113 



may be detected in samples from one locality ; and Welch, 

 who is the foremost x\merican authority, has more than 

 once confirmed my conclusions. See his papers for 1917 

 and igig in the appended Bibliography. The synonymy 

 is in part given by Michaelsen (4), but in the light of recent 

 research this must be amended, and the list of habitats 

 (p. 80) made to include England, Ireland, Scotland, Faroe 

 Islands and Canada. 



2. Marimina {Chamaedrilus) sphagnetorum Vejd. An 

 interesting note on this species is given by Southern (5). 

 I have elsewhere given my reasons for transferring this 

 species to the genus Chamaedrilus on account of the number 

 of septal glands, the free spermathecae, the shape and size 

 of the coelomic corpuscles, the colourless blood, the position 

 of the sexual organs and other pecuharities. I have found 

 it rarely in England, though its related form is abundant. 

 We now add the Faroe Islands to the other knovvn habitats. 



3. Achaeta minima Southern. — Described in 1907 (5) 

 from a specimen found in soil from Lambay. '' A minute, 

 transparent worm, 3 mm. long. Number of segments 22." 

 By an error we read that " the brain is about 12 times 

 as long as broad." I take it to mean i|- times, or twice 

 as long as broad, as was the case in the- specimen found 

 in the Faroes. My specimen agreed in every particular 

 with Southern's, except that it was about i mm. in length, 

 surely the smallest soil-worm on record. Its present known 

 distribution therefore is Lambay and the Faroes. This 

 discovery lends interest to the remaining species, which 

 has not yet been found in Ireland, but is certain to occur. 



4. Mesenchytraeus oligosetosus Friend. — This worm 

 reached me from Jersey in June, 1913, where it was collected 

 by Mr. H. Hillman. Length about 6 mm. Segments 35. 



It belongs to the group which exhibit enlarged setae 

 in the neighbourhood of the spermathecae, and was 

 described by me in the Zoologist (i). I found an 

 allied form, or possibly the same species with marked 

 differences, near Birmingham more recently. The Faroese 

 specimens agreed in every detail with those found in Jerse^-^ 

 Known distribution Jersey (Elmdon, Warwickshire), Faroe 

 Islands.
