British Enchytr&ids. By Bev. H. Friend. 139 



Habitats. — Overseal, November 1911 ; Netherhall, November 

 22, 1912; Midway, January 30, 1913. These localities are all 

 between Burton-on-Trent and Ashby-de-la-Zouck. First described 

 in Zoologist, March 1913, p. 85. 



9. Henlea trisetosa Friend. 



Length 5-6 mm. Segments 35-40. Setae sigmoid, three in 

 each set throughout. Like the last, it has four pairs of septal 

 glands, but no cesophageals, nor any salivaries. The dorsal vessel 

 arises in 9/10. First described in Zoologist, March 1913, p. 86. 



10. Henlea tubula sp. n. 



Length 10-12 mm. Segments up to 45. The most striking 

 feature is the bulb, which seems to be made up of tubes (whence 

 the trivial name), and is capped with very dark cells. No oeso- 

 phageal glands, three pairs of septals of normal type ; setae unequal 

 in length, as if some had fallen out from one side of the Fridericia- 

 like bundles. Usually 3-4 dorsal and 4-5 ventral ; seldom, if 

 ever, exceeding five. Bulb in segment 7 with dorsal vessel in inter- 

 segment 6/7 in front of the black cap and tubules. Sperm-funnel 

 1^ X 1, the long coiled duct ending in an atrial gland half as 

 large as the funnel. Coelomic corpuscles not horny or clear, but 

 granulated, in healthy worms embedded in a thick coelomic fluid. 

 Brain incised behind, rather longer than broad, Henlean in charac- 

 ter. Large sac-like salivaries in front of first pair of septals. 

 Sperinathecse with distinct duct and ampulla, with or without 

 4/5 glands. Posterior of nephridia merging in short duct. Large 

 interspaces between the girdle cells. 



Habitat. — Several localities in and around Dublin : Canal 

 Side, Dundrum Eoad, Balls Bridge, and St. Doulough's, March 

 1913 ; now first described." See Irish Naturalist, September 1913, 

 p. 172, for the first record. 



10. Henlea mariona Friend. 



Length 10 mm., stout. Segments about 50. Setse up to eight 

 in front and behind ; those in anterior bundles Fridericia-like, i.e. 

 shortest in the middle of each set. Only two pairs of septals ; 

 front pair very large, second pair smaller, with spermathecse be- 

 tween them. No oesophageal glands. Sperm-funnel small, 

 l£-2 x 1, with fine irregularly coiled duct ; large atrial glands and 

 pores on segment 12. Bulb-like enlargement in 9 or 10, with 

 the dorsal vessel arising in 10/11, pulsating forward. Girdle 

 extending from seta- of segment 11 to setae of 13. First pair of
