2. Henlea r/landulosa Friend. 



Length 10-12 mm., segments 35. Setas 4-6, those in anterior 

 portion of the body shortest in middle of the bundle, as in 

 Fridericia. Three pairs of septals in normal position, 4/5, 5/6, 6/7, 

 the hindmost pair the largest. Girdle cells small; large pores, 

 and prostate or atrial glands on segment 12. Sperm-funnel about 

 2x1, attached to long duct, irregularly coiled. Ccelomic cor- 

 puscles large and discoid. Xo oesophageal glands; intestine 

 enlarged in segment 7, with dorsal vessel arising in front of septum 

 7/8. Head and brain small, the latter of tlie usual type, about 

 IJ X 1, and slightly indented (or concave) behind. Dorsal vessel 

 irregularly branched in the iburth segment, and pulsing in those 

 behind. The spermathecae have no distinct ampulla, but there are 

 glands at the opening. Anteseptal of nephridia small, postseptal 

 large. No salivaries seen. It resembles in some details Henlea 

 mai'ina, but differs from H. hibernica and H. nasuta in the matter 

 of oesophageal glands. This may be shown thus : —

Eeceived from the Rev. W.- Johnson, Poyntzpass, Ireland, May 



1912, in soil at the roots of Primula, which were supposed to be 

 suffering through worms. Described in Irish Naturalist, January 



1913, p. 9. 



3. Henlea pusilla sp. n. 



A very tiny worm ; extending to 2 mm. in length, with about 

 30 segments. Seta? 3-4 per bundle. White, witli yellowish 

 intestine. Three pairs of septal glands in the normal position. 

 One pair of cesophageal glands in segment 8, where the dorsal 

 vessel takes its rise. Coelomic corpuscles small, and not of the 

 true Henlean type. Brain not concave or incised behind as usual, 

 but convex. Salivaries present in segment 5, sac-like, and un- 

 divided (fig. 34). Nephridia large, with posterior end narrowing 

 into the duct (fig. 35), and ciliary movement of the canals plainly 

 visible. Comes near Henlea atteniiata, from which it differs widely, 

 however, in length, as well as in the shape of the brain, the 

 number of seta?, and the position of the oesophageal and salivary 

 glands. 



Found under Marchantia hy the overflow sluice of the canal.
