British Enchytrmds. By Rev. H. Friend. 141 



Fridericia bretseheri Southern. 



When Southern created this species he assumed that it was 

 already known as F. parva Bret. ; and as the name parva had 

 already been appropriated, he changed the name. But F. parva 

 Bret, is quite distinct from F. bretseheri Southern, and both are 

 British. 1 draw attention to the point here, and will refer to 

 Southern's own works (5, 6) for his definition. Bretscher's species 

 will be discussed later. 



Fredericia bulbifera sp. n. 



Length 5-1 mm ; slender. Segments 35-40. Setae four un- 

 equal in segments 2-16 or thereabouts, and two equal thence to 

 end. Brain egg-shaped, largest behind. Spermathecae with duct 

 about twice as long as bulbous ampulla and the posterior attach- 

 ment ; glands at 4/5 present or absent. Salivaries long, often ex- 

 tending back to 5/6 unbranched. Nephridia in anterior segments, 

 with bulbous anteseptal and distinct duct ; those behind with 

 pointed anteseptal and postseptal merging into a duct. Girdle 

 12 to half 13, with large gland-cells. Sperm-funnels small. Dorsal 

 vessel arising in or near segment 16. Three pairs of septals, the 

 posterior pair sometimes having forward processes, so that at first 

 sight there appear to be four pairs of glands. Another member of 

 the bulhosa group. 



First taken at Portobello, Dublin, March 10, 1913. Oxford 

 Botanic Garden and Blenheim Palace in April, and frequently in 

 Notts in May to July 1913. 



Fridericia coronata sp. n. 



Length 15, stretching to 20 mm. Segments 50, opaque, 

 yellowish, and resembling Heulea dicksoni in appearance. A stout 

 worm, difficult to study alive. Setae never exceed four in front ; 

 in the middle and posterior usually one dorsal, and one, two, or 

 three ventral setae present. The larger setae strongly curved 

 within, and tending to a central bulb or bulging. Brain convex 

 before and behind, with under! ap. Salivary glands much branched 

 behind. Spermathecae very characteristic ; with long, somewhat 

 slender duct, and a coronet of small glands around the ampulla 

 (fig. 19). Girdle in normal position, with large male pores. Funnel 

 about 4x1, rather long and narrow, with long irregularly-coiled 

 duct. Dorsal vessel arising in or behind segment 16. Charac- 

 teristic nephridia, with medium anteseptal, large postseptal with a 

 lobe or indentation behind, and duct much exceeding postseptal in
