I have found this species usually at fairly high altitudes. The specimens 

 were all small, 5-6 mm. long. Vejdovsky gives 15 mm. as the length. 

 Otherwise the specimens agree closely with the descriptions and figures given 

 by Vejdovsky. (28. taf. vii., fig. 1-16).

Family LTJMBRICID^. 

 Genus Eiseniella. 



Numerous species and sub-species of this genus have been described. 

 All the British and Irish specimens which I have examined belong to the 

 typical form of E. tetraedra (Sav.). E. macrura, described by Friend (11. 

 p. 461) from a single specimen found at Malahide, Co. Dublin, has not 

 since been found. 



Eiseniella tetraedra (Sav.), typ. 

 1893. AUurtis tetraedrus + A. arnpMsbaena + A. Jiavus, + A. t. var. 

 obscurus + A. t. var. hiteus, Friend in Proc. Eoy. Irish Acad. (3), vol. ii., p. 462. 



^ Note added in pues.s. — I have just received from Mr. Evans of Edinburgh a number of large 

 Enchytrisids, which on examination prove to be Fridcricia magna. Friend [Zoologist (4), 1899, 

 vol iii., p 262). This species is not recorded elsewhere in this paper, but it occurs also in Ireland, 

 as I liave recently found it on Bray Head, Co. Wicklow. The description given by Friend is 

 fairly complete, and easily seiTes to characterize the species. It is very remarkable in having 

 blood of a bright red colour.
