ampulla. Length varying much, from 5 to 15 mm. Segments 

 30 to 50.

British Records. — With the foregoing by the Eden at Carlisle, 

 January 1898. Perhaps found in 1896 at Eugby; Hurstmoneeux, 

 1906 ; Malvern, 1909 ; Newton Moss and other localities, 1911. 

 A widely distributed species in Britain (Southern, Contributions, 

 p. 159). Michaelsen places Fridericia parva Moore here. I 

 reported F. parva for Carlisle years ago in The Naturalist. 



9. — Fridericia perrieri Vejdovsky. 



Setffi usually 6 in ventral and 4 in lateral bundles. Brain 

 convex before and behind, somewhat longer than broad. Salivary 

 glands with two sets of twigs, one behind the other. Two diverti- 

 cula to spermathecee. The dorsal vessel in the specimens which I 

 have examined always rises behind the girdle, and not in the 

 7th segment as Michaelsen (Das Tieireich, p. 98) doubtfully 

 suggests.

British Records. — I am not sure of my earliest records at present, 

 but think they date from 1896. Definitely in 1898, I have 

 noted it, and often later. Newton Moss and Sutton Broad, 1911. 



10. Fridericia hegcmon Vejdovsky. 



Setffi 4-8 per bundle. Brain projecting in front and convex 

 behind, a little longer than broad. Salivary glands much branched. 

 Dorsal vessel arising in segment 18. Many small diverticula 

 opening into the small ampulla. About 30 mm. long.

British Records.— May 3, 1899, from Mr. S. T. Dunn, B.A., 

 with Enchytranis parvulus Friend {= F. argenteus Mich.), among 

 decaying fritillary bulbs (Soutliern, Contributions, pp. 164-5) 

 for Irish localities. In February 1903 I received some decaying 

 celery from Dublin which was attacked by two or three species of 

 Enchytrffiids. Fridericia hegemon was mentioned in my early 

 notes as one of the offenders, but the number of stalked diverticula 

 to the spermathecte was much fewer than is usually found in that 

 species, and I now incline to refer it to another. 



11. Fridericia magna Friend. 



Ptemarkable for its size and the colour of the blood. Segments 

 about 90, length 35-40 mm. Tliere are two setre in each bundle 

 posteriorly, and 3 or 4 in front. Each segment has some half- 

 dozen rings of glands, and the girdle covers the whole of segment
