12 with half of 11. The dorsal vessel arises in 18, and there are 

 heart-like enlargements in the 7th, 8th, and 9th. The brain is 

 almost as broad as long, convex behind and slightly incised in 

 front. The spermathecae have two diverticula, and two conspicu- 

 ous brown glands occupy the opening between segments 4 and 5 

 at the end of the duct. 



British Records. — Found first at Cockermoutb, April 6th, 1899, 

 in damp soil by the side of the stream (Tbe Zoologist, 1899, vol. iii. 

 p. 262); Sutton Park, near Birmingham, Hastings, and elsewhere. 

 Southern, Contributions, p. 1G5, lias a footnote as follows : — " I 

 have just received from Mr. Evans of Edinburgh a number of 

 large Enchytr?eids, which, on examination, prove to be Fridericia 

 , magna Friend. This species is not recorded elsewhere in this 

 paper, but it occurs also in Ireland, as I have recently found it on 

 Bray Head, Co. Wicklow. It is very remarkable in having blood 

 of a bright red colour." In allusion to this, Evans says (p. 117), 

 " Several specimens of this form were found under stones beside 

 the Water of Leitli, four miles above Balerno, on 26th March, 

 1909." 



For some years after finding the last-named species I was 

 unable to follow up my researches, and it was not till Southern 

 took up the matter, and published his results in 1907 and 1909, 

 that anything further was done in the study of our Fridericia 

 fauna. 



12. Fridericia hretscheri Southern. 



In the Irish Naturalist, xvi. p. 73, Southern records the dis- 

 covery of Fridericia joarra Bret., and as Moore had already em- 

 ployed the term parva the name was changed to Bretseheri. 

 Southern says : — " The Irish specimens differ from the Swiss in 

 some details. Worms received from Edinburgh differ still more 

 widely from the type. The anterior bundles contain 4, rarely 

 5 set?e. The spermatheca bas no gland at the base. The brain is 

 not much longer than broad, and the salivary glands are un- 

 branched. The Irish worms are intermediate between the Scotch 

 and the Italian." (Contributions towards a Monograph, 1909, 

 p. 160). 



British Records. — Co. Dublin (Friarstown Glen ; summit of 

 Montpelier) : among old leaves on roadside near Aberdour, Feb- 

 ruary, 1909 (Evans). I place here a worm, found years ago in 

 Carlisle, and reported to The Naturalist, August, 1898, as Fridericia 

 parva Moore. 



13. Fridericia aurita Issel. 



To the naked eye yellowish, somewhat rigid and sluggish in 

 movement. Length 12-17 mm., with 45-60 segments. Set^
