British Encliytrmds. By Ikr. H. Friend. 17 



straight and short, 4 in a bundle in front, gradually diminishing 

 to 3 and 2. Brain about 2.^ times longer than broad ; salivaries 

 shaped like a large pouch in front and simply bifurcate behind. 

 Spermathecie voluminous, with pear-shaped ampulla and large 

 auricular diverticula. 



British Records. — Recorded by Southern, Irish Naturalist, 1907, 

 xvi. p. 74, with figure ; found at Bray Head, co. Wicklow, and 

 Lambay, co. Dublin ; has not yet been reported for England or 

 Scotland. 



14. Fridericia connata Bretscher. 



Closely resembles F. h'setosa Lev., but is easily distinguished 

 therefrom, and from all other bisetose forms, by the characteristic 

 spermathecffi, as figured in Eevue Suisse de Zoologie, 1902. 

 Southern, Irish iSTaturalist, 1907, p. 75. 



British Records. — Port Erin, Isle of Man ; Lambay, Milford, 

 and Kilruddy, in Ireland ; Acresford and Nottingham, November 

 1911. 



15. Fridericia pohjchxta Bretscher. 



Length, 13-20 mm., with about 60 segments. Ventral setre 

 4-8, and dorsal 4-7 in front, fewer behind. Brain about twice as 

 long as broad, concave in front, slightly convex behind. Salivaries 

 much branched. A long narrow duct to the spermathecffi, which 

 have large diverticula directed towards the head. Revue Suisse de- 

 Zoologie, 1900, viii. pp. 450-1. 



British Records. — Ireland, counties Kerry, Dublin and Donegal, 

 Southern; my specimens collected at Sutton Broad in August,.. 

 1911, like Southern's, differ in some details from Bretscher's de- 

 scription. 



16. Fridericia minu/a Bretscher. 



Length, 10-12 mm. ; segments about 60 in number. Setse 

 4-6 per bundle. Brain oval, concave in front, about twice as long 

 as broad. Sparsely branched salivaries. Spermathecae with two 

 large diverticula, as broad as the ampulla, with long duct, but 

 without glands at the exterior orifice. It will be seen that the 

 differences between some of the species are very slight, and 

 Southern joins minuta with auricidata (Contributions, p. 162). See 

 Revue Suisse de Zoologie, 1900, viii. pp. 32-4. Bretscher's figures 

 seem to indicate very clearly that, in Switzerland at least, the two 

 are distinct. 



British Records. — Barmouth in AVales ; counties Kerry, Dublin, 

 and Wicklow in Ireland, Southern. I have records for certain 

 English localities which need sifting.
